Charge Roll Service Check
Service Tip: Close and evenly spaced repetitive marks 47.19 mm
(1.86 inch) apart or spots on the page can be caused by a damaged
or contaminated charge roll.
Service Tip: Check to make sure the right charge roll arm bushing is
correctly installed and operates correctly.
To remove the charge roll:
1. Wrap a piece of plain white paper around the charge roll to
prevent contamination or damage.
2. Carefully remove the roll by pressing outward and to the right on
the charge roll link arm and remove the charge roll from the
right side charge roll bearing.
3. Remove the charge roll from the left side charge roll bearing
and remove the roll from the printer. Leave the paper wrapped
around the charge roll until it is reinstalled.
