Check the charge roll for correct installation, toner buildup, marks,
cuts, or other signs of contamination or damage. Replace as
necessary.

operation. Check for damage to the arm or bearing assembly.

Right charge roll bushing
Check the right side charge roll link assembly for correct assembly
operation. If incorrect, replace the charge roll link assembly with the
charge roll link assembly kit. If correct, check the right charge roll link
assembly bearing for signs of wear or contamination. Excessive
contamination could cause intermittent charging of the charge roll. If
incorrect, replace the link assembly. Check for continuity of the right
link assembly from the bearing to the charge roll high voltage contact
on the right side frame. If incorrect, replace the link assembly.
Make sure the charge roll bushing is installed and operating correctly.
Note:
The screw that attaches the charge roll lead to the contact
must be secure.
