Main charge cleaning MPC4504

[Mr2crazed]

This may be a rather stupid question but how to you get to the main charge roller to clean it? I have a a machine that has a line in grayscale from a dirty main charge roller. The service manual doesn't document how to remove the main charge.

No details in manual because you are expected to replace entire PCU unit, but its probably similar to previous models.

Same as any other Ricoh, split the drum & dev units then you can see the charge roller.
If however you're getting white lines try cleaning the laser glass & also check the dev roller for a visible deletion.

if its the same as the 03 models, turn it on its side and theres two screws on the underside to remove the charge roller assy.
