Disassembly Overview
This chapter contains the removal procedures for field-replaceable parts listed in Chapter 5,
Parts List. In most cases, the replacement procedure is simply the reverse of the removal pro
-
cedure. In some instances, additional steps are necessary and are provided for replacement of
the parts.
WARNING
Unplug the AC power cord from the wall outlet before servicing the printer.
Standard Orientation of the Printer
When needed, printer orientation is called out in the procedure as an aid to locating parts.
Refer to Figure 1 to identify the right, left, front, and back sides of the printer.

Preparation
CAUTION
Following reassembly, but before restoring power, be sure the components are all in their
home positions, otherwise damage to the printer will occur. Refer to the Adjustment proce
-
dures at the end of this chapter for procedures on setting components to their home positions.
Before you begin any removal procedure:
1. Switch off the printer power and disconnect the power cord from the wall outlet.
2. Disconnect all computer interface cables from the printer.
3. Wear an electrostatic discharge wrist strap to help prevent damage to the sensitive elec-
tronics of the printer circuit boards.
4. Allow adequate time for the printer to cool.
NOTE: Names of parts that appear in the removal and replacement procedures may not
match the names that appear in the Parts List. For example, a part called the Registration
Chute Assembly in a removal procedure may appear on the Parts List as Assembly,
Chute REGI.
