Other Problems
Symptom
Line images skew as shown in the illustrations below.
Skew Type #01: Edge of the line at the rear side positions behind the edge at the front side in paper
feed direction.
Skew Type #02: Edge of the line at the front side positions behind the edge at the rear side in paper
feed direction.
Cause
The CK laser unit is not mounted level on the copier and causes the laser beams emitted on the OPC
drum to skew.
This copier does not have a skew adjustment motor for the K (black) laser unit because the laser beams
emitted from the K unit are used as reference for other colors (C, M and Y). Skew adjustments for C, M
and Y are performed automatically with the skew adjustment motors.
Solution
Insert shims in between the CK laser unit and copier frame to level the CK laser unit.
Procedure
1. Enter SP2-109-003 (Test Pattern/Pattern Selection) and select 14: Trimming Area.
