[4] UNPACKING AND INSTALLATION
1. CHECKING PACKED COMPONENTS
AND ACCESSORIES
As you unpack the WorkCentre, familiarize yourself with its contents.
After the WorkCentre is installed, and the Ready Indicator is lit, the
WorkCentre is ready to make copies.
IMPORTANT: Save the carton and packing materials. They should be
used to repack the WorkCentre if it has to be shipped
for servicing or in case you move.
∗Note: To ensure reliability of the WorkCentre use the IEEE-1284
compliant parallel cable that is supplied with the machine. Only
cables labeled "IEEE-1284" can be used with your Work-
Centre.
2. Installation
Follow the steps below to properly set up your Xerox WorkCentre.
1) Remove the bag from the WorkCentre.
2) Remove the pieces of tape A, B, C,
D, and the packing material E.
XD155df copier only
Remove the tape and the packing material
supporting the clear plastic 2-sided tray.
XD155df copier only
To ensure the 2-sided tray is in the
correct position, gently push it in the
direction shown by the arrow.
3) Open the document cover and
remove the packing materials shown.
4) Unscrew and remove the shipping
screw from the left side of the
WorkCentre.
CAUTION: The WorkCentre will
malfunction if the shipping
screw is not removed.
5) Lift and pull open the paper tray.
Turn and remove the paper tray
button.
CAUTION: Paper will misfeed if the paper
tray button is not removed.
For the XD 120f/124f/155df copier only
Note: Be sure to remove the pressure
plate lock from both paper trays.
6) Secure the paper tray button and the
shipping screw in the locations shown.
●Turn the paper tray button to secure
its storage position.
Note: Save the paper tray button and the
shipping screw. They will be
needed if the WorkCentre has to
be moved.
7) Load paper into the tray.
●Refer to the Loading Paper section
for additional information.
●Do not fill above the max line.
8) Push the paper tray firmly back into
the WorkCentre.
Note: Ensure that the alternate paper tray
is lowered (XD 104/124f/155df only).
9) Press the release lever to open the
side cover.
10) Remove the Caution tape from the
cover.
11) Remove the two red fuser pins by
pulling the string upward one at a
time.
●Discard the fuser pins.
Note: Misfeeds will occur if the fuser pins
are not removed.
CAUTION: Ensure that the side cover is
always open before opening
the front cover.
12) Press the front cover release buttons
to open the front cover.
13) Remove the starter toner cartridge
from the silver bag. Vigorously shake
the cartridge to loosen the toner.
●Thoroughly shaking the cartridge will
assure maximum copies per
cartridge.
●Xerox has included a Starter Toner
Cartridge. Purchased replacement
toner cartridges will yield
approximately three times the number
of copies.
14) Remove the toner cartridge cover.
15) Slide the toner cartridge into the
WorkCentre until it locks into place.
16) Close the front cover and the side
cover.

repack the WorkCentre if it has to
be shipped for servicing or moved.
3. P Loading Paper
1) Lift and pull open the paper tray.
2) Push down on the pressure plate
until it locks in position.
Note: The procedures for loading paper
into tray 1 and tray 2 are identical.
3) Adjust the paper guides to the
desired paper size.
●Squeeze the side guide.
●Lift and insert the rear guide.
●When adding paper larger than
8.5L11/A4, remove the rear guide and
store it in the pocket in front of the
side guide.
4) Fan the paper and insert it into the
tray.
●Ensure that the paper corners are
under the corner snubbers.
●Do not fill above the max fill line.
5) Close the paper tray.
6) If copying, press Start to continue. If
printing, the job will automatically
resume.
●To cancel the flashing P without
restarting copying, press the Clear
button.

1. D-D (Duplex to Duplex) mode
paper/document transport
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-SPF 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 trans-
ferred.
→The paper is passed through the fusing sec-
tion 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-SPF gate solenoid ON. The document is
sent to the intermediate tray, (but not dis-
charged completely.)
→It is stopped once and switchback operation
is performed.
→It is sent through the PS roller and the ex-
posure section (without exposure operation)
to the document exit section.
→R-SPF 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 sec-
tion, and the PS roller, and the images on the
back are transferred.
→It is sent through the fusing section and dis-
charged to the paper exit tray.
Switchback operation is made after back copying in order to discharge
documents according to the setting.

1. When this simulation is executed, the currently set correction value is displayed.
2. Enter the correction value with the 10-key, press the START key, and the entered value is stored. (Correction
value: 1 - 99, Correction zero: 0 or 50)
∗For front printing in S-D mode and even-page printing in D-S mode, reverse memory copying made from the rear
edge of the document.
If, therefore, it is required to adjust the print position of the output image, perform the following procedure.
When the document is scanned in the direction shown in the figure below, images are printed from the scanning
rear edge in reverse memory copying.
If the print head is shifted, set the reference chart so that the reference position is at the rear edge section and
use this simulation so that the lead edge of the print image is fitted.
Printing is started at the print start position in the direction from the bottom to the top of image data stored in the
memory.
When the simulation set value is entered, the scanning end position and resultantly the bottom data position stored
in the memory are changed to adjust the image lead edge position.
2 Duplex copy rear edge void adjustment (Operation/Procedure)
1. When this simulation is executed, the currently st value is displayed in top digits. (Center value: 50 However, Set
value 50 = Set value 0)
2. Press the copy mode select key to select the set mode and the display.
3. Enter the adjustment value with the 10-key and press the START key, and the entered value is stored and a copy
is made.
4. Press the CLEAR key, and the entered value is stored and the simulation is terminated. (An increase in the set
value by 1 corresponds to an increase in void amount by 0.1 mm.)

(4) Mirror motor circuit
The mirror motor is a stepping motor. Its driver is IC113 constant-current chopper control IC (SLA7024). For control, the CPU outputs a drive
signal to IC113 to drive the mirror motor by 1-2 phase excitement.
The SPF motor and the mirror motor are switched with relays RY1 and RY2. The switching signal is SMSEL-. When SMSEL- is LOW, a current
flows through the SPF motor. When it is HIGH, a current flows through the mirror motor.
(5) Duplex motor circuit
The duplex motor is a stepping motor. Its driver is IC111 darlington-sink transistor driver IC (TD62064AP). For control, the CPU outputs a drive
signal to IC111 to drive the duplex motor by 1-2 phase excitement.
