Introduction

Removal and replacement strategy

This chapter documents the removal and replacement of field replaceable units (FRUs) only for
the output devices.
Replace parts in the reverse order of their removal. Directions for difficult or critical replacement
procedures are included.
WARNING! The sheet-metal edges of the output device can be sharp. Use caution when working on the output
device.
Note Note the length, diameter, color, type, and location of each screw. Be sure to return each screw
to its original location during reassembly.
Incorrectly routed or loose wire harnesses can interfere with other internal components and can
become damaged or broken. Frayed or pinched harness wires can be difficult to locate. When
replacing wire harnesses, always use the provided wire loops, lance points, or wire-harness
guides.

the output device at an ESD-protected workstation, or use an ESD mat.
Watch for the ESD symbol (shown at left) to identify the parts that are sensitive to ESD. Protect
these parts by using an ESD wrist strap and protective ESD pouches.
CAUTION A pozidriv screwdriver will damage screw heads on the output device. Use a #2 Phillips
screwdriver.
If you use a multispeed screwdriver, use a torque limiter.
