 GENERAL PRECAUTIONS REGARDING THE SERVICE FOR
THIS DSDF
The installation and service shall be done by a qualified service
technician.

1. When installing the DSDF to the Equipment, be sure to follow the instructions described in the
“Unpacking/Set-Up Procedure for the DSDF” booklet which comes with each unit of the DSDF.

2. The DSDF shall be installed by an authorized/qualified person.

3. The equipment must be grounded for safety.

4. Before starting installation, servicing or maintenance work, be sure to turn OFF and unplug the
equipment first.

5. The equipment shall be installed near the socket outlet and shall be easily accessible.

6. Be sure to fix and plug in the power cable securely after the installation so that no one trips over it.

7. Unplug the power cable and clean the area around the prongs of the plug and socket outlet once a
year or more. A fire may occur when dust lies on this area.

8. The DSDF should be grounded to the specified positions on the machine frame.

9. When servicing or maintaining the DSDF, be careful about the rotating or operation sections such as
gears, pulleys, sprockets, cams, belts, etc.

10.Reassembly of disassembled parts is the reverse of the disassembly unless otherwise noted in this
manual or other related documents.
Care should be taken that small parts, such as screws, washers, pins, E-rings, star washers,
harnesses are not installed in the wrong places.

11. Basically, the machine should not be operated with any parts removed or disassembled.

12.When servicing the equipment with the power turned ON, be sure not to touch live sections and
rotating/operating sections.

13.Delicate parts for preventing safety hazard problems (such as switches, sensors, etc. if any) should
be handled/installed/adjusted correctly.

14.Use suitable measuring instruments and tools.

15.During servicing or maintenance work, be sure to check the serial No. plate and other cautionary
labels (if any) to see if they are clean and firmly fixed. If not, take appropriate actions.

16.The PC board must be stored in an anti-electrostatic bag and handled carefully using a wristband,
because the ICs on it may be damaged due to static electricity. Before using the wrist band, pull out
the power cord plug of the equipment and make sure that there is no uninsulated charged objects in
the vicinity.

17.For the recovery and disposal of used DSDF, consumable parts and packing materials, follow the
relevant local regulations/rules should be followed.

18.Do not leave plastic bags where children can get at them. This may cause an accident such as
suffocation if a child puts his/her head into a bag. Plastic bags of options or service parts must be
brought back.
19.There is a risk of an electric shock or fire resulting from the damage to the harness covering or
conduction blockage. To avoid this, be sure to wire the harness in the same way as that before
disassembling when the equipment is assembled/disassembled.

20.After completing installation, servicing and maintenance of the DSDF, return the DSDF to its original
state, and check operation.

21.Check the procedures and perform as described in the Service Manual.

22.Make sure you do not lose your balance.

23.Avoid exposure to your skin and wear protective gloves as needed.

24.After the power cable is disconnected, an electric charge may remain in the boards of the
equipment. Therefore, be sure to disconnect or connect the connectors when about 1 minute (e.g.:
the time for taking off the rear cover) has passed after the power cable is disconnected.

25.The DSDF equips the function to transmit its adjustment values to the equipment only at the first
normal startup (power OFF/ON) once the DSDF has been installed.
This function will not work when the equipment is started in the self-diagnosis mode by means of
pressing buttons on the control panel or at the easy set-up mode during unpacking. Therefore, even
if various adjustments of the DSDF are carried out in the self-diagnosis mode at the first startup of
the equipment once the DSDF has been installed, the values set in the adjustment are overwritten
by the adjustment values of the DSDF when the normal startup (power OFF/ON) is performed since
they are transmitted at this timing.

In addition, this function will not work when the DSDF, which was already installed in another MFP, is
installed in other one. In such a case, perform FS-05-3240 and FS-05-3400 in order to transmit the
adjustment values of the DSDF to the equipment. (When they are performed, the adjustment values
of the DSDF or RADF which was previously installed will be changed.) In the similar way, when the
DSDF is replaced with the RADF, perform FS-05-3401. (When this is performed, the adjustment
values of the DSDF which was previously installed will be changed.)

3.2.3 DSDF separation motor
The DSDF separation motor performs the reverse operation of the original separation roller and moves
(up/lowering) the original tray lift.

When original feeding starts, the DSDF separation motor rotates clockwise to perform the reverse
operation of the original separation roller.
This will prevent multiple feeding of an original.

Moreover, when the DSDF empty sensor is turned ON, the DSDF separation motor rotates 3
counterclockwise, resulting in the original tray lift going up.
When the DSDF empty sensor is turned OFF, the DSDF separation motor rotates counterclockwise,
resulting in the original tray lift lowering.
Transmitting the driving force from the DSDF separation motor to the original tray lift is controlled by the
DSDF tray-up clutch.

When the DSDF exit motor rotates counterclockwise, the DSDF exit roller starts rotating to exit an
original.
When the DSDF exit motor rotates clockwise, the guide covering the DSDF shading sheet starts
rotating and then it appears.
The home position of the guide covering the DSDF shading sheet is detected by the DSDF shading
sheet HP sensor.

3.3 Original Size Detection
The size of the original on the original tray is detected by the combination of the DSDF tray original
width sensor, DSDF tray original length sensor-1 and -2.
Moreover, in the mixed size mode, after an original on the original tray has been fed and transported,
the original size is detected again by the combination of the DSDF original width detection sensor-1 and
-2 and the DSDF registration sensor to determine the paper size.

3.3.1 DSDF tray original width sensor, DSDF tray original length
sensor-1 / -2
The DSDF tray original width sensor, DSDF tray original length sensor-1 and -2 detect the size of an
original placed on the original tray.

It is detected by the brush attached to the rack moving on the original tray width sensor, which is a
board with the different length of the patterns written. This brush is moved as the original width guide is
moved. Signals (TWID0S, TWID1S, TWID2S) are opened and shorted to SG by this movement. The
combination of these short (= low level) and open (= high level) can determine the width of the original.

The size of the original is determined by the combination of the ON/OFF status of the DSDF tray
original width sensor, DSDF tray original length sensor-1 and -2. Therefore, if the sensors cannot detect
the size of the original properly due to its being folded or bent, an incorrect size may be detected.

Sizes detectable in combination of these open and short of the signals are as follows:

DESCRIPTION OF OPERATIONS

3.3.2 DSDF original width sensor-1 and -2 / DSDF registration sensor
In the mixed size mode, the size of the original is determined by the size which is detected by the DSDF
tray original width sensor, DSDF tray original length sensor-1 and -2 located on the original tray by
adding the result of the redetection during its transportation.
Redetection is performed by the ON/OFF status of the DSDF tray original width sensor-1 and -2 and by
the period in which the DSDF registration is ON (transportation period) to determine the original size.

Sizes detectable in combination of these sensors are as follows:

6.9 DSDF separation roller pressure force adjustment
In some cases the life of the separation roller may be shortened or paper jams (E712, E721) and
multiple feeding (E724) may occur regardless of the operation frequency of the DSDF. This comes from
the weight or edge status of paper used and the amount of paper dust.
Generally paper jams and multiple feeding often occur as the life end of the roller approaches.
However, if they often occur even though its life has not yet reached its replacement timing, or if the life
end comes much earlier than the scheduled replacement timing, the jams and multiple feeding can be
suppressed by adjusting the pressure force of the separation roller.
In this method; however, when the roller life becomes longer, jams and multiple feeding may occur
frequently, and when the jams and multiple feeding are suppressed, the roller life may become shorter.
Therefore, perform this adjustment while checking the status carefully, and if necessary, give a
sufficient explanation to users.

(1) Remove the DSDF pickup unit [1].

(2) Open the DSDF separation roller cover [1].

Classification Error content

DSDF jam The DSDF original jam access cover has become open during DSDF
operation.
The paper exit motor has been driven and the DSDF shading sheet HP
sensor has not been turned ON within a specified time.

Details:
If this problem has occurred at the start of a duplex copying or scanning job
or at the end of a copying or scanning job, the cover may have opened as a
result.

The home position detection is carried out by the DSDF shading sheet HP
sensor when the cover or the DSDF is closed, the power is turned ON,
during the initial operation or at the end of a job. This home position
detection checks that the DSDF shading sheet HP sensor is turned ON
within a specified time after the DSDF exit motor has started driving.
If the home position cannot be detected when the cover or the DSDF is
closed or the power is turned ON, a cover open error will be displayed.
If the home position cannot be detected during the initial operation or at the
end of a job, a DSDF shading sheet HP sensor abnormality will occur and
this error code will be displayed.
