Preparation
Before you begin any removal and replacement procedure:

2. Turn the printer power Off and disconnect the power cord from the wall outlet.
3. Disconnect all computer interface cables from the printer.

the Registration Chute Assembly in a removal procedure may appear on the
Parts List as Assembly, Registration Chute. When working on a removal
procedure, ignore any prerequisite procedure for parts already removed.

Many parts are secured by plastic tabs. Do not over flex or force these parts.
Do not over torque the screws threaded into plastic parts.

part.
