Disassembly Overview

This section contains the removal procedures for field-replaceable parts listed in the Parts List.
In most cases, the replacement procedure is simply the reverse of the removal procedure. In
some instances, additional steps are necessary and are provided for replacement of the parts.
Phaser 8860/8860MFP Differences
With the exception of the DADF, Scanner, Exit Module, covers, and some electronics, the two
models are essentially the same. To indicate procedures unique to a particular model, the REP
title includes the model number. Procedure titles without a model number are correct for either
model and begin with a Note referencing where to start the procedure. In cases where the part
number is unique to a particular model, both parts list references appear at the begining of the
procedure (PL 1.0 for 8860MFP Covers or
unique, are listed in Section 5. Use the parts diagrams when selecting replacement parts.
Unplug the AC power cord from the wall outlet before servicing the system.
Standard Orientation of the System
When needed, system orientation is called out in the procedure as an aid to locating parts.
Refer to the following figure to identify the right, left, front, and back sides of the printer.

WARNING
Preparation
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 procedures at the
end of this section, for procedures on setting components to thier 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 system.
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 system 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.
