NOTE:
If the SIT chart is not available, execute Sim. 63-5 to set the
CCD gamma to the default. In this case, however, the adjustment
accuracy is lower when compared with the adjustment method
using the SIT chart.

Copy image quality adjustment
(1) Precautions before the copy image quality adjustment
Necessary requirements for execution of the copy image quality adjustment
Before execution of the copy image quality adjustment, the following items on the copy density and the gradation must be adjusted properly.
In normal cases, however, there is no need to frequently adjust them. When a trouble occurs, check and adjust according to necessity.

In normal cases, however, there is no need to frequently adjust them. When a trouble occurs, check and adjust according to necessity.
(Relationship between the servicing procedures and the copy image quality adjustment)
Note that the procedures before and after the copy density and gra-
dation adjustment differ depending on the machine status and the
servicing procedures.
Follow the copy density and gradation adjustment procedures to
perform the proper procedures according to the status.
The following four cases require density and gradation adjust-
ments.
