SERVICE MANUAL
 IMPORTANT SAFETY NOTICES
PREVENTION OF PHYSICAL INJURY
1. Before disassembling or assembling parts of the printer and peripherals,
make sure that the power cord is unplugged.
2. The wall outlet should be near the copier and easily accessible.
3. 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.

HEALTH SAFETY CONDITIONS

1. If you get ink in your eyes by accident, try to remove with eye drops or
flush with water as first aid. If unsuccessful, get medical attention.
2. If you ingest ink by accident, induce vomiting by sticking finger down
throat or by giving soapy or strong salty water to drink.

OBSERVANCE OF ELECTRICAL SAFETY STANDARDS

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

SAFETY AND ECOLOGICAL NOTES FOR DISPOSAL

1. Dispose of replaced parts in accordance with local regulations.
2. Used ink and master should be disposed of in an environmentally safe
manner and in accordance with local regulations.

– CAUTION –

The RAM pack has a lithium battery which can explode if handled
incorrectly. Replace only with same RAM pack. Do not recharge or burn
this battery. Used RAM packs must be handled in accordance with local
regulations.

2. SCANNER
2.1 OVERALL
A book type scanner is used for the #C218/#C219 models. There are 2
modes for scanning originals.
Platen Cover Mode: The original is placed on the exposure glass, and the
scanner motor drives the scanner to scan the original.
ADF Mode: When an optional Document Feeder is installed, the original is
fed onto the exposure glass. The scanner moves 24 mm away from the CCD
and remains still as it scans the original. The scanner comes back to the
home position when the scanning is finished.

[I]

[H] [A]
[C]
[G]
[B]
[F]

[E]
[D]

[G]: Reflector

The light from the fluorescent lamp [A] is reflected from the original, by the
first [B], second [F], and third [E] mirrors and goes through the lens [D] into
the CCD [C].
In the Platen Cover Mode, the CCD reads the white plate [H] on the back of
the original scale [I] each time before scanning to obtain a standard white
level. The standard white data are used to correct distortion. The scanner is
at its home position when it reads the white level.
In the ADF mode, as the scanner moves 24 mm, the CCD reads the white
plate installed on the ADF.

2.2 SCANNER MECHANISM

[B]
[Front Side]

[E]
[D]

[C]

[F]

[Rear Side]

[A]
[G]

A stepper motor is used for the scanner motor [A] to drive the scanners. The
first scanner [B], which consists of the exposure lamp and the first mirror, is
driven by the first scanner belt [F]. The second scanner [C], which consists of
the second and the third mirror, is driven by the second scanner belt [D]. Both
scanners move along the guide rails.
The timing belt [G] moves the second scanner at half the velocity of the first
scanner. This is to maintain the focal distance between the original and the
lens during scanning.
The scanner home position is detected by the home position sensor [E]. In
the Platen Cover Mode, the scanner scans the original on the exposure glass
for the full A3 length, then returns until the scanner home position sensor is
activated. In the ADF Mode, the scanner moves 24 mm backwards (away
from the CCD), to scan the original which is fed by the ADF. When the
master making process is finished and the ADF motor stops, the scanner
goes back to the home position.

15 July 1994 SCANNER

2.3 PLATEN COVER POSITION DETECTION

[B]

[A]

When the platen cover is opened about 25 degrees, the Platen Cover
Position Sensor [A] is deactivated. When this sensor is deactivated, the
Original Sensor [B] is able to detect the original on the exposure glass.
When the Platen Cover Position Sensor is deactivated and the Original
Sensor detects no original on the exposure glass, the machine indicates
"SET THE ORIGINALS" on the operation display. This is to prevent wasting
of the master that would occur when the Master Making key is pressed with
no original placed on the exposure glass.
When the original is placed on the exposure glass and the Master Making
key is pressed with the platen cover opened more than 25 degrees (as the
Platen Cover Position Sensor is deactivated), the shadow erase function is
enabled.

2-5
SCANNER 15 July 1994

Notes regarding the shadow erase function:

• Margins of 1 mm, 0.02" on all four sides of the original will be erased. The
width of the margins will change depending on the reproduction ratios.
• Shadows near the book edge might not be erased completely.
• If the shape of the originals are as shown below, shadows might appear
on the prints. In this case, make the master with the platen cover closed.

T1: After the master eject process is completed, the main motor starts
reverse rotation at 30 rpm. At the same time, the master feed motor and
the reverse roller magnetic clutch turn on to feed the master 21.5
millimeters (18.5 mm for the C219 model).
T2: The master feed clamper solenoid is energized when the drum rotates
160 degrees past the second drum position sensor (162 degrees for the
C219 model). At the same time, the reverse roller magnetic clutch is
turned on and the scanner motor starts to rotate.

SCANNER 15 July 1994

T3: When the scanner has moved 20 millimeters from its home position (17
mm for the C219 model), the master starts to be fed. When the master
has been fed 0.9 millimeters (1.0 mm for the C219 model), the thermal
head starts plotting on the master.

The leading edge is zero when the scanner is 12 millimeters from its
home position. The leading edge margin can be adjusted within the range
of 4 to 10 millimeters by SP mode No.33.
T4: When the master has been fed 38 millimeters (41 mm for C219 models),
the reverse roller magnetic clutch turns off. Then the master is fed 5
millimeters more and the master feed clamper solenoid is de-energized to
close the master clamper. The master is fed in the same way as in #C210
models. The original transport and the master feed motors speed up once
the master plotting is done. The master feeding lengths for plotting are:

For #C218 models

412 millimeters: A3/DLT drum
204 millimeters: A4/LT drum
For #C219 models
355 millimeters: for both B4 and LG drums
T5: When the scanner has scanned the full scanning length (the same length
as the master feeding length), the scanner motor starts its reverse
rotation to bring back the scanner to the home position.
T6: The master feed motor stops when the master has been fed 534.4
millimeters (479.5 mm for the C219 model). At the same time, the cutter
motor starts rotating to cut the master. The cutter motor changes its
rotation direction when the cutter holder pushes the right cutter switch.
The cutter motor stops when the cutter holder goes back to the home
position to activate the left cutter switch (the same way as in #C210
models).

When the right cutter switch is activated, the drum starts rotating to go
back to its home position. When the left cutter switch is activated (when
the cutter comes back to its home position), the master feed motor turns
on again to feed the master 40 millimeters.
T7: When the scanner motor stops its reverse rotation, the scanner motor
rotates forward until the scanner home position sensor is activated.

When the drum release lever [A] in front of the machine is raised, the

link [D], and is disconnected. The bracket [C] also pushes the drum lock lever
[F] to release the drum lock allowing the drum to be removed. While the drum
is away from its home position, the drum lock solenoid [G] is energized and
the stopper [H] locks the link [D] to prevent the drum from being pulled out.
The solenoid is de-energized when the drum stops at the home position
(when the 1st drum position sensor is actuated).
