MX-M264U ADJUSTMENTS AND SETTINGS 5 – 15
10) Loosen the CCD unit fixing screws.
CAUTION: Never loosen the screws marked with X.
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 mar-
ket. In that case, the whole scanner unit must be
replaced.
11) 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 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.
* Fix the CCD unit so that it is in parallel with the line marked
in procedure 9).
12) Make a copy and check the copy magnification ratio again.
If the copy magnification ratio is not in the range of 100 1%,
repeat the procedures of 9) - 11) until the condition is satisfied.
CAUTION: By changing the CCD unit fixing position with the simu-
lation 48-1 adjustment value at 50, the copy magnifica-
tion ratio is adjusted within the specified range (100
1.0%) and the specified resolution is obtained based on
the optical system structure.
