[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.
Power cord
IEEE-1284 Parallel Cable * Packing material User documentation/ Installation CD
Drum cartridge (installed in the machine)
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. q 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. q Refer to the Loading Paper section for additional information. q Do not fill above the max line. 8) Push the paper tray firmly back into the WorkCentre.
Starter toner cartridge
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 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.
2. Installation
Follow the steps below to properly set up your Xerox WorkCentre. 1) Remove the bag from the WorkCentre. D A 2) Remove the pieces of tape A, B, C, D, and the packing material E. E C XD155df copier only Remove the tape and the packing material B 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.
10) Remove the Caution tape from the cover. 11) Remove the two red fuser pins by pulling the string upward one at a time. q 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.
3) Open the document cover and remove the packing materials shown.

Note: Save the carton and packing materials. They should be used to 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. q Squeeze the side guide. q Lift and insert the rear guide. q 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. q Ensure that the paper corners are under the corner snubbers. q 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. q To cancel the flashing P without restarting copying, press the Clear button.

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.

(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.
