 !IMPORTANT SAFETY NOTICES
PREVENTION OF PHYSICAL INJURY
1. Before disassembling or assembling parts of the copier and peripherals,
make sure that the copier power cord is unplugged.
2. The wall outlet should be near the copier and easily accessible.
3. Note that some components of the copier and the paper tray unit are
supplied with electrical voltage even if the main power switch is turned off.
4. If any adjustment or operation check has to be made with exterior covers off
or open while the main switch is turned on, keep hands away from electrified
or mechanically driven components.
5. If the Start key is pressed before the copier completes the warm-up period
(the Start key starts blinking red and green alternatively), keep hands away
from the mechanical and the electrical components as the copier starts
making copies as soon as the warm-up period is completed.
6. The inside and the metal parts of the fusing unit become extremely hot while
the copier is operating. Be careful to avoid touching those components with
your bare hands.

HEALTH SAFETY CONDITIONS

1. Never operate the copier without the ozone filters installed.
2. Always replace the ozone filters with the specified ones at the specified
intervals.
3. Toner and developer are non-toxic, but if you get either of them in your eyes
by accident, it may cause temporary eye discomfort. Try to remove with eye
drops or flush with water as first aid. If unsuccessful, get medical attention.

OBSERVANCE OF ELECTRICAL SAFETY STANDARDS

1. The copier and its peripherals must be installed and maintained by a
customer service representative who has completed the training course on
those models.

1
 1. SAFETY AND ECOLOGICAL NOTES FOR DISPOSAL
Do not incinerate toner bottles or used toner. Toner dust may ignite
suddenly when exposed to an open flame.
2. Dispose of used toner, developer, and organic photoconductors in
accordance with local regulations. (These are non-toxic supplies.)
3. Dispose of replaced parts in accordance with local regulations.
4. When keeping used lithium batteries in order to dispose of them later, do not
put more than 100 batteries per sealed box. Storing larger numbers or not
sealing them apart may lead to chemical reactions and heat build-up.

Lithium Batteries (Memory Back-up)

!CAUTION
The danger of explosion exists if a battery of this type is incorrectly
replaced.
Replace only with the same or an equivalent type recommended by the
manufacturer. Discard used batteries in accordance with the
manufacturer’s instructions.

Away from the motor Shorter

4. Measure the spring length again with calipers to confirm that it is correct.

Fine Adjustment
During normal operation the spring, bracket, and sensor move out of the home
position to the correct position determined by automatic software calculations for
the paper type, fusing mode setting, and fusing roller temperature.

check the effect of each adjustment.
• Adjusting these SPs up in intervals of 10 (410, 420, etc.) switches off one
LED for every interval, and adjusting down 10 switches on one LED.
• Adjusting these SPs up less than 10 (411, 412, etc.) decreases the light
intensity of the LED, and adjusting down less than 10 increases the light
intensity.
• Adjust the lines until they are faint; the lines cannot be completely erased.

ADJUSTMENTS

1. Skew adjustment for long printouts

1. Set normal weight plain paper (841 mm wide/E size, from roll 1) and print an
IPU dot pattern with SP2941-1 (IPU Test Pattern – Pattern 11), of length 6 m,
and output to the rear exit.
2. At the rear paper exit, measure the amount of skew on the output. Make sure it
is within the standards below.
Allowed skew < 1 mm per meter

3. If the amount of measured shift is not within standards, adjust the right and left
fusing pressure from the pressure roller with the following SP codes.
SP1914 002 Fusing Pressure Roller Motor – Right Pressure Adjustment
SP1914 003 Fusing Pressure Roller Motor – Left Pressure Adjustment

If the paper is skewed to the right, weaken the pressure on the right roller, then
increase the pressure on the left roller.
To determine if there is skew, look at the trailing edge.
The SP values must be the same size, but of opposite sign (for example, if SP
1914 002 is –10, SP 1914 003 must be + 10). The difference between the two
SP values must be less than 30.

If roller pressure adjustment is not successful, return the SP settings to their

previous values. Then do the next procedure to adjust the line speed, and then
try again to adjust roller pressure.

Production
Symptom:
When HDD Spindle Control is
disabled (default), SC980 may
occur just after the machine
recovers from Auto Off / Panel Off.
Cause:
When the machine is brought out of
these modes, it is able to warm up
quicker than when the main power
is turned on, and therefore checks
the HDD status at an earlier point.
However since the HDD must
warm up from a stop, it does not
reach ready speed in time and a
mainframe/HDD communication
error occurs.
Solution:
The default setting for HDD Spindle
Control (SP4960-005, 006) has
been changed from
Off ! On, which keeps the HDD
rotating constantly.
Note: When installing the HDD option
in the following machines, please
change the setting of SP4960-005
and 006 from Off ! On:
B010-27: J201060001 – J201060040

2. New UP mode added (Weekly

below), the “Weekly Output Volume”
setting has been added to System

Symptom: B0105162 B B0105172 B Sep.2001 6.06

When customers use low duty mode
to make high-volume copy jobs
(relative to the ACV), the toner
concentration in the development unit
increases. This causes the
oversupplied toner to drop onto the
copies, especially under low
temperature conditions.
Solution:
Change the “Weekly Output Volume”
according to the customer’s average
weekly copy volume from inside
System Setting – General features:
Less than 750m (2,500 ft): Low duty
mode (default).
More than 750m (2,500 ft): High duty
mode
Action in the field:
Please instruct customers on the
following points at machine
installation:

Service
Tables
1) Method for how to enter UP Mode
and change the Weekly Output
Volume value.
2) For the first 1-2 months following
installation, have the customer keep
track of their copy volume at weekly
intervals. The weekly changes in CV
over this time will enable them to
decide which of the 2 settings is best
for them.

Note: For customers installing the

B010 as a replacement machine,
please use the weekly ACV on the
previous machine for reference and
set the Weekly Output Volume
accordingly (as a starting point).

6.2.5 ORIGINAL TEMPORARY DELAY

[C]
Inserting the leading edge of the [B] [D]
original [A] into the feed slot switches [A]
on the original set sensor [B], and
brings it into contact with the edge of
the original feed roller [C].
The interval between the time the
original set sensor switches on until B010D551.WMF
the feed roller starts turning is called
Delay 1. It can be set from 1 to 5
seconds with the “Original Feed Delay 1” user tool. This delay allows the user to
manually shift the original from side to side to correct the alignment of the original.
After Delay 1 expires, the original is fed at 105 mm/s to the registration sensor [D],
where the original pauses again for 1 to 5 seconds. This is called Delay 2 and this
delay allows time for the user to pull the original out if it has fed incorrectly. The
length of Delay 2 can be set with the “Original Feed Delay 2” user tool.

6.2.6 SCANNING MECHANISM

In this machine, the scanning unit [A] is above
the original feed path [B]. This eliminates copy
quality problems caused by foreign objects [A]
falling into the scanner.

B010D103.WMF

This machine also uses a contact image

sensor [A] (CIS System !), which scans
black and white originals up to 926 mm
(361/2") wide at 600 dpi.
The original moves past the scanning unit.

6.3.2 ORIGINAL MODES

Overview
Here is a brief summary of the original modes that the user can select for this
machine at the operation panel.

Mode Function
Text Best reproduction of text and sharp lines. When Text is selected, the
auto image density feature is automatically switched on.
Photo Conducts dither processing for photo originals to remove jagged
edges. Achieves the best reproduction for copied photographs. When
Photo is selected, the auto image density feature is automatically
switched off.
Text/Photo Achieves the best reproduction for originals with text and photos on
the same page. When Text/Photo is selected, the auto image density
feature is automatically switched on.
Pale Best reproduction of originals which may be difficult to read, such as
penciled documents, thin sheets, copies of copies of forms, and any
original of low contrast that may require enhancement. When Pale is
selected, the auto density feature is automatically switched on.
Generation Similar to the Text mode, but attempts to reduce the thickness of thick
characters, restore the thin or broken lines of originals, ignore the
background texture, and erase independent dots that tend to appear in
copies of originals which are 2nd, 3rd, etc. generation copies
themselves.
Patched Original Prevents the background from appearing in copies of originals where
the textures of the backgrounds differ. For example, this mode will
even out the backgrounds and eliminate the shadows and lines on
pages or boards pasted up for design layout.
Blue Line Ignores only blue lines in the original. For example, the blue grid
squares of graph paper, or the markings with a dropout blue pencil do
not appear in copies.
Photo Uses 4-value error diffusion. Good for copying posters that contain
(Hard Tone) photos with text overlays. 4-Value Error Diffusion is applied in the
Photo (Hard Tone) mode. It can be adjusted with SP4903 006 Image

6.3.3 INDEPENDENT DOT ERASURE

The user selects the required amount of independent dot erasure, using a user tool
(Copier Features – General Features – Noise Reduction). There are four settings:
Off, Low, Medium, and High.
The threshold values for each setting can be adjusted with SP modes 4906 70~81.
The user tool setting applies to the Text, Pale, Text/Photo, and Generation Copy
original modes. Independent dot erasure is also used with the Blue Line and
Patched Original modes, but there are no user or SP adjustments.
For example, Text mode uses the following SP modes.
• 4906 073: Low (L)
• 4906 074: Medium (M)
• 4906 075: High (H)
The adjustment is done on a 5 x 5 pixel matrix with the 10 pixels to the left and
right of the matrix.

SP4906 070~081 Independent Dot Erasure

0 Independent dot erasure is not executed.
1~14 When surrounding pixels are each less than the selected SP mode
value (nn), the targeted pixel is removed.

As shown in the table below, as values are selected farther to the right, more dots
are erased.
SP Value 1 2 3 4 5 6 7 8 9 10 11 12 13 14
Text Mode 8 16 24 32 40 48 56 64 72 80 96 112 128 144

The algorithm operates as follows:

• If any value in the shaded is larger than the SP setting, the target pixel is not
removed.
• If no value in the pixels is greater than the SP setting, then the 10 pixels to each
side of the matrix are checked:
• If any value in the 10 pixels to each side of the matrix is larger than the target
pixel, the target pixel is not removed.
• If no value in the 10 pixels to each side of the matrix is greater than the SP
value, the target pixel is removed.

6.3.4 FOUR-VALUE ERROR DIFFUSION

This method of error diffusion, implemented for the first time on a wide format
copier, is similar to 256-grayscale error diffusion but with one important difference.
Instead of testing each matrix and assigning it a value on the 0~255 scale, each
matrix is tested and then processed according to which one of 4 ranges it fits into
on the 0~255 scale.
The 0~255 scale is divided into 4 sections. Sections 1, 2,
3, and 4 are assigned binary values (00, 01, 10, 11) in
ascending order.
This method of error diffusion is not as accurate as true
error diffusion. However, it requires much less memory,
resulting in much faster processing times and less
demand on memory resources. B010D513.WMF

This feature is only used with Photo (Hard Tone) Mode.

The strength can be adjusted with SP4903 006.

6.3.5 MTF SETTINGS

The MTF (Modulation Transfer Function) filter coefficient and strength can be
adjusted for the following requirements:
• Sharp reproduction of text and lines on the same page.
• Sharp lines in copies reduced in size.
• Removal of rough textured background.
• Improved reproductions of low-contrast originals.
The settings for an MTF filter coefficient and strength can be adjusted separately,
in order to achieve optimum performance according to how the customer is
routinely using the machine.

Descriptions
Detailed
If higher values are selected for both the coefficient and strength settings, the
performance of the filter is enhanced. If the strength of the filter is increased, the
reproduction of low contrast documents is improved but the occurrence of moiré
increases.
NOTE: For Photo (Hard Tone) Mode (4-Value Error Diffusion) the strength can be
increased only with SP4903 006 (Image Setting – Smoothing Filter Level
Photo).
For more details about the range of SP adjustments available, see Section “5

The paddle roller picks up developer in its paddles and transports it to the

The rotation of the sleeve carries developer toward the OPC drum. Developer back
spill from the doctor blade goes either to the separator then the developer agitator,
or to the auger then the paddle roller.
A filter relieves the pressure that tends to build up in the development unit.
The toner density is constantly monitored by an ID sensor (there is no TD sensor).

6.6.2 DEVELOPER CROSS-MIXING [C]

The doctor blade [A] trims the developer [A]
to the specified thickness. The developer
then passes to the separator [B]. The [B]
separator guides the developer at an [D]
angle, so that it cross mixes from left to
right.
Toner falls through a hole [C] at the right
end of the separator. The auger [D]
transports this toner in the opposite B010D301.WMF
direction of the separator, from right to left,
to achieve cross-mixing.
Together with toner density control, this
method of cross-mixing prevents
fluctuations in toner density, which can
cause uneven printing.

The rotation of the toner agitator [A] [C]

[A]
sends new toner to the developer
agitator [B], where it is mixed with

Copying
The CBG (Charge, Bias, Grid) power pack
applies [A] a negative bias (-700V) to the
development roller, slightly higher than the
residual charge on the drum.
The development bias during copying
depends on SP 2201 001.
[A]
Making ID Sensor Patterns
The machine has two ways of making the
ID sensor patterns. These are Low Duty
Mode and High Duty Mode. The mode
B010D904.WMF
used depends on SP 2201 004.
If the average copy volume is high (2.5
km/month or more), switch to High Duty to
prevent toner scattering.
However, if the machine is in High Duty Mode and the average copy volume
⇒ becomes low again the image density may decrease. If this happens, switch back
to Low Duty Mode.
The ID sensor pattern development bias voltages for high and low duty modes can
be adjusted with SP 2201 002 and 003, as shown in the following table.

The density is used to determine whether
more toner is needed.
The ID sensor pattern is made after each
copy, if 100 cm of copies have been made
since the last ID sensor pattern check.
This interval can be changed with SP3920
B010D905.WMF

6.6.7 TONER END/NEAR-END CONTROL

Near-end Detection
Near-end occurs if the ID sensor reads Vsp/Vsg values three times in succession
that are larger than the Vend value specified with SP2927 001 (Toner End Level),.
End Detection/Recovery from Near-end
After the machine enters the near-end status, the ID sensor pattern check
accelerates from 100 cm to 20 cm intervals.
Then, the machine changes status in accordance with the following conditions:
• Toner End: Toner end occurs if Vsp/Vsg stays continuously more than Vend
while a certain length of paper is printed. Then the toner end message is
displayed, and machine operation halts. The length of paper depends on SP
2927 002 (default setting: 1500 cm).

If Vsp/Vsg drops below Vend, the distance count stops. But, if the next Vsp/Vsg
reading exceeds Vend again, the count begins again from the previously
accumulated total.

• Recovery from Near-end: If Vsp/Vsg drops below Vend three times in

succession, then the following happens:
• The machine is released from the near-end status
• The distance counter is reset to zero
• The ID sensor pattern check interval is restored to its original value (this
interval depends on SP3920; the default is 100 cm intervals).

6.6.9 TONER DENSITY CONTROL

Overview
The machine controls toner density by switching the toner supply clutch on/off, with
on/off timing determined by the ID sensor readings from the sensor pattern on the
drum.
Toner Supply Modes
This machine has three toner supply modes. These are detect mode, fixed mode
(3%), and fixed mode (6%).
The mode that is used depends on the setting of SP 2208 003. The default is
detect mode.
In detect mode, the machine uses the ID sensor to control toner supply.
If the ID sensor breaks, SC code 353 is generated. The machine does not
automatically switch over to fixed supply mode.
If a spare sensor is not available, SP 2208 003 must be set to fixed mode. For
example, select fixed mode (3%) if the user’s copies are generally 3% black
coverage.
Then, after installing a new ID sensor, set SP 2208 003 back to detect mode.

The paper feed section consists of two roll trays and the by-pass feed table. Each
paper source can be selected from the operation panel.
The first roll tray contains two rolls (roll 1 is at the front of the machine, and roll 2 is
towards the rear). The second roll tray (optional) contains one roll (roll 3).

 PAPER FEED AND REGISTRATION

Inserting the original starts the feed motor and the registration motor, and paper
feed begins. The paper is fed from the paper supply source, passes the feed exit
roller and is fed into the machine by the registration rollers.
The registration rollers halt temporarily to allow paper skew correction, and then
start again to feed the paper to the drum.
Next, the cutter cuts the paper after the specified paper length has been fed
(monitored by the cutting sensor). The starting time of the cutter depends on the
cutting mode selected at the operation panel (preset cut, synchro cut, or variable
cut).
After the last cut of a job, the feed roller reverses and returns the edge of the paper
to its home position away from the vertical part of the feed path. This ensures that
the paper path is not obstructed when paper feed starts for the next job.

6.7.2 PAPER HOLDER [A]

6.7.7 CUTTING MECHANISM

There is a cutter unit on each roll tray. [A]
The rotary disk cutter [A] can cut in either
direction. When it comes to rest at the
home position [B] on either end of the
cutting unit, a cam opens the paper holder
for the next paper feed.
Before cutting, the registration roller
continues to rotate at normal speed, but
the roll feed motor speed increases [B]
slightly. This causes the paper to buckle
slightly between the registration roller and
the top of the cutter.
When the cutter motor switches on, the cutter starts to move. This closes the paper
clamp to hold the paper at the cutting position. The cutter disk pushes the paper
against a horizontal blade behind the paper, and moves across the paper, cutting
as it moves.
The registration roller continues to turn during cutting. At this time, the slack
generated between registration roller and cutter is taken up. This allows paper feed
past the drum to continue at the same speed during cutting.
To cut a sheet from a roll of freshly loaded paper, press the auto feed key for the
1st or 2nd roll to feed paper, then release the key to cut. Paper will continue to feed
for as long as the auto feed key is pressed.
The paper can also be cut by pushing the handle on the cutter to the left or right.

⇒ 6.7.8 PAPER ROLL REVERSAL

There is a roll lead edge sensor for each paper
roll. The sensors detect the presence of paper
in the guide below the cutter.
At the end of every copy job the paper roll
reverses to remove paper from the vertical
paper guide. This allows other paper rolls to be
selected. The roll lead edge sensors,
determine if paper has reversed far enough to
clear the vertical paper guide.

⇒6.7.9 ROLL END DETECTION [A]

Roll end is detected with reflective

photosensors that detect the
exposed, black core of an empty roll.
In the 1st roll tray unit, the
[C]
photosensors [A] are mounted above
the two paper rolls.
In the optional 2nd roll tray unit, the [B]
photosensor [B] is mounted in front
of the paper roll.
In addition to the photosensors, two
paper end sensors [C] are mounted in
the 1st roll tray, and one paper end B010D906.WMF
sensor [D] is mounted in the optional [D] [C]
2nd roll tray. These paper sensors
detect the end of the paper roll if the
core of the paper roll is any other color
than black and cannot be detected by
the photosensors.

⇒6.7.10 CONDENSATION PREVENTION

6.8 IMAGE TRANSFER AND PAPER SEPARATION

6.8.1 OVERVIEW
The transfer corona unit [A] uses a
tungsten wire (φ80 µm) which at transfer
applies about +5 kV to transfer toner from
the drum to the paper.
The separation corona [B] applies about
ac 4.5 kV and dc +350V to separate the
paper from the drum.

[B]
[A] B010D102.WMF

6.8.2 TRANSFER AND SEPARATION TIMING CONTROL

SP2925 002 determines when the machine switches the transfer current over from
the current for the leading edge (relatively weak) to the current for the image
(relatively strong).
If there is insufficient toner transfer at the leading edge of the image, adjust this SP
so that the switchover point is earlier. However, this can cause paper separation at
the leading edge to be less effective.
Also, if paper separation at the leading edge is poor, adjust the SP so that the
switchover point is earlier. However, this can cause insufficient toner transfer at the
leading edge of the image.

6.8.3 PICK-OFF PAWL OPERATION

The pick-off pawls separate paper from the
drum when the separation corona fails. [A]
The pick-off pawl solenoid brings the pick-
off pawls into contact with the drum.
When the leading edge of the paper on the
drum enters the separation corona unit with
about 198 mm (7.8") of the paper in contact
with the drum, the solenoid [A] switches on.
The pick-off pawl shaft starts to rotate, and

6.10.3 TEMPERATURE AND PRESSURE CONTROL

The fusing pressure is automatically adjusted, so
nip-band width is not required.
During warm-up and during printing, the pressure
roller thermistor [A] monitors the temperature of [A]
the pressure roller to determine the target control Hot Roller
hot roller temperature. (☛ Table 6-1)
The hot roller thermistor [B] monitors the actual [B]
temperature of the hot roller, and the CPU
determines the difference between the actual
temperature and the target control temperature.
Based on this data, the pressure on the hot roller
[C] is increased or decreased, until the leading Pressure Roller
edge of the paper reaches the fusing unit. (☛
Table 6-2)
If the hot roller temperature drops below a certain
level during printing, the CPU uses CPM Down [C]

6.10.8 WRINKLE PREVENTION

[A]

[B]
[C] B010D550.WMF

The speed of the paper at the fusing rollers [A] is slightly faster than at the
registration rollers [B] to ensure that the correct amount of tension is maintained on
the paper [C] between the registration and fusing rollers. This prevents wrinkling in
the fusing unit.
However, after the paper leading edge is grabbed by the fusing unit, the paper
moves past the drum faster than previously, which could enlarge the image slightly
in the sub scan direction. To prevent this, both the registration and fusing motors
slow down slightly (by the same amount) when the leading edge of the paper
reaches the exit sensor.
The distance between the registration roller and exit sensor is about 360 mm
(14.2"), so this motor speed correction is only used when paper is longer than 360
mm.

6.11.4 SWITCHING EXITS

Paper longer than A1 sideways paper
must exit at the rear, because the front
paper exit does not have a large tray.
[B]
Selecting the paper exit on the operation
panel switches the paper junction gate
solenoid [A] on and off to open and close
the junction gate [B], which selects the
paper exit path.
• Solenoid on: Rear exit

The machine does not automatically [A]

select the correct exit if the paper is longer B010D601.WMF

than A1 sideways. Change the exit

selection on the operation panel.

to prevent condensation around the feed rollers.
Two heaters prevent condensation around the drum.
Contact Image Sensor (CIS) The CIS unit is a strip of photodiodes to illuminate the original,
and a strip of phototransistors covered by a row of self-
focusing lenses. The CIS contacts the original directly, so the
size of the scanner unit can be reduced.
Fusing Lamps There are two fusing lamps inside the hot roller.

SM 7-9 B010
SPECIFICATIONS Rev. 3/2002

Fusing Thermofuse Provides backup overheat protection for the fusing lamps. If
thermistor overheat protection fails, the thermofuse opens and
cuts power to the fusing lamps.
Hot Roller Thermistor Located very close to the hot roller, the CPU uses this
thermistor to monitor the hot roller and control the operating
temperature of the fusing unit.
Pressure Roller Thermistor Located very close to the pressure roller, the CPU uses this to
monitor the pressure roller temperature.
PSU Cooling Fan Cools the PSU (Power Supply Unit) board.
Quenching Lamp Illuminates the OPC drum to remove residual electric charge
immediately after cleaning, which prepares the drum for
charging in the next copy cycle.
Total Feed Meter Counts all feeds from the first copy cycle. The metered total
always remains unaffected by resets, memory clear, etc.

6.6.3 DEVELOPMENT BIAS

Copying
The CBG (Charge, Bias, Grid) power pack

development roller, slightly higher than the
residual charge on the drum.
The development bias during copying

Making ID Sensor Patterns
The machine has two ways of making the
ID sensor patterns. These are Low Duty
Mode and High Duty Mode. The mode
B010D904.WMF
used depends on SP 2201 004.
If the average copy volume is high (2.5
km/month or more), switch to High Duty to
prevent toner scattering.
However, if the machine is in High Duty Mode and the average copy volume
⇒ becomes low again the image density may decrease. If this happens, switch back
to Low Duty Mode.
The ID sensor pattern development bias voltages for high and low duty modes can
be adjusted with SP 2201 002 and 003, as shown in the following table.

INFORMATION
" GENERAL
SUBJECT: HDD SPINDLE CONTROL
Note: This copy is intended as a master original
for reproduction of additional bulletins.

GENERAL:

The following explains the timing and default settings of SC980 and their affect on the HDD Spindle control.

SYMPTOM:

"
SOFTWARE
When HDD Spindle Control is disabled (default), SC980 may occur just after the machine recovers from
Auto Off / Panel Off.

CAUSE:
When the machine is brought out of these modes, it is able to warm up quicker than when the main power is
turned on, and therefore checks the HDD status at an earlier point. However since the HDD must warm up
from a stop, it does not reach ready speed in time and a mainframe/HDD communication error occurs.

SOLUTION:
The default setting for HDD Spindle Control (SP4960-005, 006) has been changed from Off ! On, which
keeps the HDD rotating constantly.

ACTION IN THE FIELD:

When installing the HDD option, please change the setting of SP4960-005 and 006 from Off ! On:

Control) setting changed

Production
Symptom:
When HDD Spindle Control is
disabled (default), SC980 may
occur just after the machine
recovers from Auto Off / Panel Off.
Cause:
When the machine is brought out of
these modes, it is able to warm up
quicker than when the main power
is turned on, and therefore checks
the HDD status at an earlier point.
However since the HDD must
warm up from a stop, it does not
reach ready speed in time and a
mainframe/HDD communication
error occurs.
Solution:
The default setting for HDD Spindle
Control (SP4960-005, 006) has
been changed from
Off ! On, which keeps the HDD
rotating constantly.
Note: When installing the HDD option
in the following machines, please
change the setting of SP4960-005
and 006 from Off ! On:
B010-27: J201060001 – J201060040
(40 units).
2. New UP mode added (Weekly
Output Volume)
To prevent toner scattering from the
development unit (see conditions
below), the “Weekly Output Volume”
setting has been added to System
Setting – General Features.

Symptom: B0105162 B B0105172 B Sep.2001 6.06
Production
When customers use low duty mode
to make high-volume copy jobs
(relative to the ACV), the toner
concentration in the development unit
increases. This causes the
oversupplied toner to drop onto the
copies, especially under low
temperature conditions.
Solution:
Change the “Weekly Output Volume”
according to the customer’s average
weekly copy volume from inside
System Setting – General features:
Less than 750m (2,500 ft): Low duty
mode (default).
More than 750m (2,500 ft): High duty
mode
Action in the field:
Please instruct customers on the
following points at machine
installation:

Service
Tables
1) Method for how to enter UP Mode
and change the Weekly Output
Volume value.
2) For the first 1-2 months following
installation, have the customer keep
track of their copy volume at weekly
intervals. The weekly changes in CV
over this time will enable them to
decide which of the 2 settings is best
for them.

Note: For customers installing the

B010 as a replacement machine,
please use the weekly ACV on the
previous machine for reference and
set the Weekly Output Volume
accordingly (as a starting point).

3) During these first couple of months,
if the average weekly copy volume
exceeds 750m (2,500 ft), please have
the customer change the setting of
the Weekly Output Volume to “More
than 750m (2,500 ft)”.

Note: Please also check the total

counter value at PM visits, calculate
the weekly CV, and if necessary
change the Weekly Output Volume

SUBJECT: SC951 (DURING PRINTING ONLY)

„
for reproduction of additional bulletins.

ELECTRICAL
SYMPTOM:
An SC951 (F-Gate Signal Error) is generated while performing a print job.

CAUSE:
The machine switches over to Low CPM mode during a print job, causing the interval between sheets to
increase. The controller does not get a fast enough response from the mainframe, causing an error at the
controller side.

NOTE: The machine tends to switch over to Low CPM mode when it cannot maintain a high enough
fusing temperature, such as when prints are made right after the machine reaches Copy Ready
or recovers from Energy Saver Mode. Furthermore, the machine has a greater tendency to
switch over to Low CPM mode when large volumes of prints are made continuously under such
conditions.

COUNTERMEASURE:
In order to minimize occurrences of SC951, please change the following settings. These settings will ensure
that the fusing temperature remains in the optimum range:

1. System Settings – General Features – “Fusing Adjustment: Paper Tray”: Set to "3".
2. System Settings – General Features – “Panel Off Timer”: Set to "0 sec".
3. System Settings – General Features – “Energy Saver Timer”: Set to "0 sec".
4. System Settings – Key Operator Tools – “Auto off Timer”: Set to "240 min".
5. SP1917 “Ready Temp. Setting”: Set to "1" (195°C All paper types/thickness).
6. SP1103 “Fusing Idling”: Set to "3" (5min).

Corrects the following:

4. SMC printout onto undefined paper sizes

In response to a request from the field, the
SMC printouts can now be printed onto
any paper size that can be loaded into the
paper trays.

5. Occurrence conditions changed for SC353

SC353 will not be displayed during Toner
End.
This was changed because sometimes
when copying originals with a very high
image area ratio, SC353 would occur
unnecessarily when the ID sensor pattern
density dropped and the Near End
condition was detected.

6. Jam Recovery
The machine was sometimes unable to
perform successful jam recovery if a jam
occurred while printing out a series of
preset jobs.

7. Display error - number of jobs

Even after being cancelled, a preset job is
not subtracted from the total job count.

8. Part of image missing when printing out

"Additional Copies" with electronic sort,
mixed original mode
Following a mixed-original electronic
sorting job, the machine is still set to use
the paper roll it did for the last copy.
Therefore when "Additional Copies" are
initiated, instead of resetting the paper roll
to the initial one, the machine starts
printing out onto the most recently used
roll, cutting off some of the image.
Software corrected so that copies of any
additional sets are printed out onto their
correct sizes, i.e. as originally set in the
initial job.

copy job
Software changed so that when the Print
Start Trigger is set to "press start key",
originals can be scanned an unlimited
number of times before initiating the copy
job. Each time a new scan is initiated, the
previous scan data is overwritten.
Adds the following: B0105162D B0105172D June ‘02 6.11
Production
1. Missing image data with wide originals
(230V version only)
Symptom
Image data is missing on the right and left
edges (30mm from the edge) when
feeding originals over 841mm in width.
Cause
Even if Original Size Auto Detect (System
Settings, General Features 2/2) is turned
OFF, the printer/scanner controller is
informed of the maximum scanning width
of 841mm.
Solution
When Original Size Auto Detect is
deactivated and the original size sensor
for 841mm detects the original, the
machine will regard this as a width of
914mm and send this data to the
printer/scanner controller.
NOTE: Please advise users to deactivate
Original Size Auto Detect when
scanning/copying originals over 841mm in
width.

2. Scanner reserve error

Symptom
The Reserve Scanner Error is displayed in
the Scantool function of Plotbase.
Cause
The Function Reset Timer is not set to
“instant.”
Solution
The Function Reset Timer has been
deleted from System Settings – General
Features 2/3, and is now controlled from

When the printer/scanner controller is connected, the timer

should be set to “0” (instant).

NOTE: The update to version 6.11 in the field will not automatically change the Function Reset Timer
setting, therefore it is necessary to manually set this to “instant” after the update is completed.

3. New SP Mode added to enable

Continuous Original Feed (SP5957)
5 Mode Number/name Function/ [Setting]
5957 Continuous Original Feed Enables or disables the continuous feeding of originals through
the original feeder. When enabled, originals can be fed one by
one during a copy job without having to wait for each copy to
exit.

Corrects the following:

4. PM Light is displayed before 10,000m

(every 10,000 ft.)
The PM light will now be displayed on the
operation panel every 10,000 meters,
regardless of the unit set for the total
counter in SP5980.

5. Function error - User code

Even though the machine prompts the
operator to enter the User Code, it is
possible to make copies without inputting
any code.

NOTE: User Codes cannot be used with

the printer/scanner controller, even though
the operation panel displays the user code
screen.

6. Display changed for SP4428-002: Image

Scan Adjustment - Start
”Executing” remains displayed even after
the SP has completed the adjustment.
This has been changed so that no

GENERAL:

PARTS
To ensure that the gear (AB017539) does not break when the toner cartridge is installed without being
shaken, the Toner Hopper Joint Shaft has been changed as shown below.
The following parts updates are being issued for all B010 Parts Catalogs.

NOTE: Make sure developer does not get into the joint shaft unit assembly when the developer is
replaced. If developer gets into the joint part, disassemble the unit and clean it immediately.
If the developer were to remain in the assembly, it would cause joint operation problems due to
excessive mechanical load and parts wear.

SUBJECT: DIRTY BACKGROUND

COPY QUALITY
GENERAL:
Please use the following as a troubleshooting guide when dirty background is reported from the field.
.
SYMPTOM:
Dirty background (all types).

POSSIBLE CAUSES
1. SP2201-004 setting error:

„
This SP may be set for low-duty copy jobs even when copying at high volumes.
2. Incorrect ID sensor data:

INFORMATION
GENERAL
1) Dirty ID sensor.
2) Defective ID sensor.
3. Drum light fatigue:
Defective quenching lamp.
4. Developer deterioration:
1) Developer deteriorates faster when there is a Diazo machine installed nearby which emits
ammonia.
2) The developer is used past its PM interval.
5. Drum deterioration:
1) Drums deteriorate faster when there is a Diazo machine installed nearby which emits ammonia.
2) The thickness of the drum’s under layer (UL) is near specification minimum in some areas.
Specification: 3.0 +/- 0.5µm.

Backgrounding process:
With the B010 the grid voltage is set relatively high in order to bring out highlight areas more clearly.
The thinner areas at the lower limit of UL specification (2.5µm) are unable to tolerate the higher
electrical field applied to the drum surface, causing an electrical leak, which appears as dirty
background on the copy surface.

ACTION
Perform the following, making sure to check the image quality for any improvements after replacing or
cleaning any components. If at any point it returns to an acceptable level, there is no need to continue the
procedure.

1) Make copy samples.

2) Print out the SMC sheet.
3) Check the ID sensor data with SP3-103 and make sure that Vsg and Vsp are within the following ranges:
Vsg: 4.0 +/- 0.1 Vsp: 0.5 +/- 0.1
If they are not, clean the ID sensor and then make 10 copies (A1/D, sideways). This will stabilize the
toner concentration in the developer. Check the data again, and if it is still not within target levels,
replace the sensor.
4) Check to see that the quenching lamp (red LED) remains ON during copying. If it does not, check for
loose harness connections. If the connections are normal, replace the lamp.
5) Return the following SP settings back to their factory defaults (if changed).
Note: Set SP2-201-004 to "High Duty Copy Jobs" to prevent toner scattering due to low copy volume.

SP No. Description Factory setting sheet No.

-003 ID Sensor Pattern - High Duty Copy Jobs 05022010300
-004 Copy Jobs 05022010400
6) Check the PM intervals for all PM parts and replace or clean any if necessary.
Note: It is particularly important that the corona wire, grid wire and ozone filter are
not used past their PM intervals.
7) Change SP2-001-002 from –875 to –800, and SP2-201-001 from –705 to –600.
Note: This has a side effect of lowering the image density in solid image areas.
Therefore after changing these values, make sure the ID level is acceptable to the customer.
8) Replace the developer.
9) If the above procedure does not eliminate the dirty background, drum fatigue is the most likely cause,
therefore please replace the drum and cleaning blade.
