Check the charge roll for correct installation, toner buildup, marks,
cuts, or other signs of contamination or damage. Replace as
necessary.
Check the left side charge roll link assembly for correct assembly
operation. Check for damage to the arm or bearing assembly.
Check the right side charge roll link assembly for correct assembly
operation. If incorrect, replace the charge roll link assembly with the

assembly bearing for signs of wear or contamination. Excessive
contamination could cause intermittent charging of the charge roll. If

link assembly from the bearing to the charge roll high voltage contact
on the right side frame. If incorrect, replace the link assembly.
