adjustment (Individual adjustment)
a. General
This adjustment is used to execute the fine adjustment in each mode only when a satisfactory image quality is not obtained by the basic adjust-
ments ADJ 11B and ADJ 11C or there is a request from the user. Normally there is no need to execute this adjustment.
In this adjustment, the adjustment result may be applied to the image send mode and the FAX mode as well as the copy mode.
This must be well understood for execution of the adjustment.

This adjustment is used to execute the density adjustment for each
density level in each monochrome copy mode.
This adjustment must be performed in the following cases:
* When it is required to change the gamma in each copy mode.
* When there is request from the user.
1) Enter the SIM 46-16 mode.
2) Select the density level (point) to be adjusted with the scroll
