Color displacement in main scanning direction



Description

There are some reported instances from the field where cyan color displacement occurred in

the main scanning direction. When the same symptom occurs, go through the field remedy

below.



Cause

Since J1131 connectors, which extend from respective DC controller PCBs (1 through 3) to the

laser unit, had poor contact, the cyan laser beam was not output properly.



Field Remedy

1. Refit all J1131 connectors on the DC controller PCB 1-3.

2. Refit J3553C on the laser driver sub PCB ‘UN173.’

Reference:

For other colors, refer to the matrix below.
