Foggy image/black lines due to detached dustproof glass inside
the laser scanner unit
[Symptom]
Foggy image [a] and black lines [b] may occur when copying and printing. The number of black lines and the location may not
be constant.
The arrow [c] indicates the paper feed direction.
[Cause]
The double-sided tape attaching the dustproof glass [1] inside the laser scanner unit (FM3-7526-010/FM3-7531-010) is peeled
off due to insufficient pressure, the dustproof glass detaches and drops inside the machine and it obstructs the optical path,
resulting in the above-mentioned symptom.
[Service work]
1) Remove the laser scanner unit by following Service Manual.
2) Check the dustproof glass inside the laser scanner unit. If the dustproof glass is detached, replace it with the new laser scanner
unit. If it is not detached, look for another factor.
3) Return the laser scanner unit.
