Condition
When the main scanning direction
copy magnification ratio and
resolution are not in the specified
range.

Necessary condition
1) The copy image distortion is within the specified range.
2) The copy image is free from deflection.
3) The copy image density is within the specified range.

Work content
1) Enter the simulation 48-1 mode.
2) Select the main scanning direction (manual) adjustment mode
with the copy picture quality mode select key.
(The currently set copy magnification ratio adjustment value is
displayed on the copy quantity display.)

3) Set the adjustment value to 50 and press the start button.
(The adjustment value is stored and a copy is made at the copy
magnification ratio corresponding to the adjustment value.)
The adjustment value can be set in the range of 0

4) Turn off the power.
5) Check the CCD unit No. (OID) specified on the CCD unit.
6) Loosen the CCD unit fixing screw.
7) Set the dimension (L) from the CCD edge to the center of the hole
in the scanner (reading) unit to the value calculated from the
following formula, and fix it.
L = 10.5 + CCD unit No. (OID)
8) Place the scale on the document table as shown below, and make
a copy in the text copy mode at 100% in the proper density.
