This adjustment must be performed in the following cases:
•
When a U2 trouble occurs.
•
When the ICU main PWB is replaced.
•
When the EEPROM of the ICU main PWB is replaced.
Used to adjust the gamma and the density in each copy mode individually. The adjustment in each copy mode is not required normally, but is per-
