Line No.2: White lines caused by Dust Shield Glass
Cause
Light exposed to the drum is insufficient due to a dirty dust shield glass.
Procedure
1. Clean the dust shield glass.
Line No.3: Color lines caused by Charge Corona Unit
Cause
Charge level is insufficient due to a dirty charge corona unit.
Procedure
1. Press the "User tools" button on the Panel, select "Maintenance" and do "Color
Registration."
(Note that "User tools" is not indicated on the panel for EU machines. Look for the
mark on the button shown below.)
2. To identify the color causing the lines, print 3 sheets of the halftone pattern (SP2-106-
002-16) in each color.
3. Swap the charge corona unit of the affected color with another unit of a different color.
4. Again, print 3 sheets of the halftone pattern (SP2-106-002-16) in each color.
Do the vertical lines appear in a different color after swapping the charge corona unit?
YES: Replace the unit of the affected color confirmed in step 2 with a new unit to
complete the procedure.
NO: Do the troubleshooting procedures for "Line No.4."
IMPORTANT: Make sure to put the charge corona units back to their original stations to
prevent PM counter error.
