Yellow Color Partially Missing

There could be issues reported with the yellow cartridge not engaging or disengaging properly, resulting in the yellow color plane being partial or missing. This will be seen as fade from right to left on the Yellow PQ Troubleshooting page.

Figure 1: Yellow not engaging

This could happen because of the Yellow cartridge not engaging or disengaging properly.

In addition to misalignment of main drive assembly gears, this phenomenon can also be caused by improper reinstallation of the paper feed assembly cable cover in the cartridge atrium.

Figure 2: Paper Input Unit (PIU) Cable Cover not seated properly

Reseat the paper feed assembly Paper Input Unit (PIU) cable cover, being careful to route the cables properly. Cover must not sit on top of any cables; rather, it should be seated firmly at the bottom of the cartridge atrium, and should not interfere with the yellow cartridge left-side alienation cam.
