LASER SCANNER UNIT
Subject:
Measure to E020-1x60 immediately after replacing the drum unit
Symptom
E020-1x60 may occur immediately after replacing the drum unit.
- E020-1x60: Detected light patch reading value (X:0=Y, 1=M, 2=C, 3=K)
Cause
The laser scanner unit is assembled in clean room so that no dust can get inside which causes faulty images. Also the
seams of the housing are sealed up to shut out dusts from the operation environment. However, small particles of 1
micrometer or less may invade inside the machine depending upon the operation environment, and the invaded small
particles may soil the polygon mirrors. This soiling diminished laser intensity that led to the above mentioned
symptom.
