(2) Manual multi paper feed operation
1) Before paper feed operation, the manual paper feed solenoid
(MPFS) is turned OFF as shown in the figure below.
2) When the PRINT button is pressed, the manual paper feed
solenoid (MPFS) turns on to disengage the manual paper feed
latch.
A from the manual paper feed clutch sleeve A, rotating the manual
paper feed roller and the manual take-up roller. At the same time,
the manual paper feed stopper opens and the manual take-up
roller is pressed to the surface of the paper to start paper feeding.3) When pawl C of the manual paper feed clutch sleeve is engaged
with the manual feed latch, the manual feed stopper falls and the
manual take-up roller rises. At that time, the manual paper feed
roller is rotating.
4) The lead edge of the transported paper is pressed on the resist
roller by the transport roller. Then the paper is stopped temporarily
to allow synchronization with the lead edge of the image on the
OPC drum.
From this point, the operation is the same as the paper feed
operation from the tray. (Refer to A-5 - 8.)
5) The solenoid turns off to close the gate and return to the initial
state.

6. D-D (Duplex to Duplex) mode paper/
document transport (Duplex model)
A. Initial state
Set duplex documents on the document tray.
Set paper on the cassette. (In the duplex mode, the manual feed tray
cannot be selected.)
B. Front copy
Document transport:
The document feed roller feeds the document from the paper feed
roller to the PS roller.
•The document is exposed in the exposure section, and sent to the
document exit section
•by the transport/paper exit roller.
•R-ADF gate solenoid ON
•The document is sent to the intermediate tray.
(but not discharged completely.)
•The document is stopped once, then switchback operation is
performed. 
(To the back copy)
Paper transport:
The document is passed through the paper feed roller and the PS
roller by the paper feed roller
and the images on the front surface are transferred.
•The paper is passed through the fusing section and the lower side of
the gate section to the paper exit tray side, (but not discharged
completely.)
•It is stopped once and switchback operation is performed.
(To the back copy)
C. Back copy
Document transport:
By switchback operation, the document is sent through the PS roller to
the exposure section, where the back of the document is exposed.
•It is sent to the document exit section by the transport roller and the
paper exit roller.
•R-ADF gate solenoid ON. The document is sent to the intermediate
tray, (but not discharged completely.)
•It is stopped once and switchback operation is performed.
•It is sent through the PS roller and the exposure section (without
exposure operation) to the document exit section.
•R-ADF gate solenoid OFF
•The document is discharged to the document exit tray.
Paper transport:
Switchback operation is performed.
•The paper is sent through the upper side of the gate section and the
duplex transport section, and the PS roller, and the images on the
back are transferred.
•It is sent through the fusing section and discharged to the paper exit
tray. a PPD1 jam PPD1 does not turn off within 4 sec after turning 
on the resist roller.
b PPD2 jam PPD2 is off immediately after turning on the 
resist roller.
PPD2 does not turn off within 1.2 sec after 
turning off the resist roller.
c POD jam  POD does not turn on within 2.9 sec after turning 
on the resist roller.
POD does not turn off within 1.5 sec - 2.7 sec

A. List
B. Drum replacement
1) Remove the drum cover. (4 Lock Tabs)2) Remove the drum fixing plate and the photoconductor drum.
(Note) Dispose the drum fixing plate which was removed.
3) Check the cleaning blade and the red felt for no damage.
•If there is any damage, execute all procedures from item 5) and
later.
•If there is no damage, execute the procedure of item 12).
4) Remove the main charger.
(Cleaning the screen grid and the sawteeth.) Before disassembly, be sure to disconnect the power cord for 
safety.
1. Do not disconnect or connect the connector and the har-
ness during the machine is powered. Especially be careful
not to disconnect or connect the harness between the MCU
PWB and the LSU (MCU PWB: CN20) during the machine is
powered. (If it is disconnected or connected during the
machine is powered, the IC inside the LSU will be
destroyed.)
2. To disconnect the harness after turning on the power, be
sure to turn off the power and wait for at least 10 sec before
