Removal and replacement strategy
This chapter contains detailed steps and images that show parts removal. Replacement is generally
the reverse of removal. Occasionally, notes are included to provide directions for difficult or critical
replacement procedures.
WARNING! Remove the power cord before attempting to service the product. If this warning
is not followed, severe injury can result, as well as damage to the device. Certain functional
checks during troubleshooting must be performed with power supplied to the product.
However, the power supply should be disconnected during removal of any parts.
Sheet metal and plastic edges in the product can be sharp. Use caution when working on the
product.
Never operate or service the printer with the protective cover removed from the laser/scanner
assembly. The reflected beam, although invisible, can damage your eyes.
CAUTION Some parts are sensitive to electrostatic discharge (ESD). Always perform
service work at an ESD-protected workstation. If an ESD-protected workstation is not
available, ground yourself by touching the sheet-metal chassis before touching an ESD-
sensitive part.
NOTE To install a self-tapping screw, first turn it counterclockwise to align it with the existing
thread pattern, and then carefully turn it clockwise to tighten. Do not overtighten. If a self-
tapping screw-hole becomes stripped, repair the screw-hole or replace the affected assembly.
Required tools
● #2 Phillips screwdriver with magnetic tip
●
Small flat-blade screwdriver
●
Needle-nose pliers
● ESD mat
CAUTION Do not use a pozidrive screwdriver or any motorized screwdriver. These can
damage screws or screw threads on the product.
CAUTION Do not pull directly on the wires when a connector is disconnected. Always pull
on the plastic body of a connector to avoid damaging the connector wires.
Before performing service
● Remove all media.
● Unplug the power cable.

Place the product on an ESD mat (if one is available).
