Internal assemblies
When replacing internal assemblies, make sure to transfer any component parts that are not
provided with the new assembly from the failed assembly to the new assembly. For example, sensor
PCBs are not included with the fuser assembly or the paper-pickup assembly. The sensor PCB from
the failed assembly must be transferred to the new assembly.
Transfer-roller assembly
Before proceeding, make sure it is absolutely necessary to remove the transfer roller.
CAUTION Be very careful not to break the paper guide that is removed during replacement
of the transfer roller. This is not a service part. If the paper guide is broken, the entire printer
must be replaced.
CAUTION Do not touch the black-sponge portion of the transfer roller. Skin oils and finger
prints can cause print-quality problems.
1. Open the print-cartridge door, and then release the two tabs on the paper guide and rotate it up.
