If any one of these screws is loosened, the position and the angle
of the CCD unit base may be changed to cause a problem, which
cannot be adjusted in the market. In that case, the whole scanner
cannot be adjusted in the market. In that case, the whole scanner
unit must be replaced.
<5>Slide the CCD unit in the arrow direction (CCD sub scanning
direction) to change the installing position.
When the copy image is longer than the original scale, shift the
CCD unit in the direction B. When the copy image is shorter than
CCD unit in the direction B. When the copy image is shorter than
the original scale, shift the CCD unit in the direction A.
One scale of mark-off line corresponds to 0.2%.
At that time, fix the CCD unit so that it is in parallel with the scale on
the front and the rear side of the CCD unit base.
Note:Fix the CCD unit so that it is in parallel with the line marked in
