Eg. If the copy is as shown in the figure, move the exposure con-
trol plate a in the B direction to achieve the exposure balance.

Simulation 50-01 or 50-02 allows the copy adjustment.

(When using Simulation 50-01)
In this simulation, the following keys have special functions:
REDUCE key:
This key is used to set the magnification to 50%.
ENLARGE key:
This key is used to set the magnification to
200%.
For each operation of the scrol display key, A

Measure a distance from the paper end to the image (scale) end
of each copy, and calculate the values of RRC-A and RRC-B
with the following expressions:
If the preset value of RRC-A is not appropriate, the images at the
both magnifications differs in end position. RRC-B is a preset
value used to control the RRC ON-timing so that the end of the
drum image is aligned with the end of a copy paper.
