Poor copy quality with the PRT Highlights not varying from -10 when the gradation adjustment is performed.
Solution
CAUSE: The print head (laser write unit) is dirty or has failed.
SOLUTION: Clean the print head including the mirror unit mounted below the print head. Use care not to touch the glass when the mirror unit is reinstalled.
If cleaning does not resolve the problem, replace the print head (p/n 11UM-9540).
Note: The print head comes with the print head control board (PWB-JD) and the mirror assembly. All three must be replaced as a matched set.
