Skewed (Optical) Copy Image - Ricoh A151 Field Service Manual

1.11 SKEWED (OPTICAL) COPY IMAGE

- Problem -
The copy image is skewed (parallelogram shape).
The sides of the copy image are straight, but the
leading and trailing edges are skewed.
(This differs from skewing originating in the paper
path.)
- Possible Causes -
1. 4th/5th mirror assembly is not parallel with the 1st and 2nd scanners.
2. Mirrors are in the wrong position.
3. The stubs of the 4th/5th mirror assembly are off the rails.
- Action -
Is each mirror positioned correctly on its scanner and on the 4th/5th mirror
assembly?
Yes No
Reposition the mirror correctly. If the spring plates are defective,
replace them.
Are the stubs of the 4th/5th mirror assembly off the rails?
No Yes
Put the mirror assembly stubs back on the rails.
Readjust the height of 4th/5th mirror assembly by turning the adjusting screw.
