Problem
Customers have reported the yellow cartridge not printing properly with a fade from right to left (seen below on the Yellow PQ Troubleshooting page) due to a problem with the yellow toner engaging or disengaging.
Solution
Check 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 bay. This cover can interfere with the alienation of the left-side of the yellow cartridge.
