4) Cancel the simulation mode, and make a copy in the normal
mode to check the copy density in the white area and the low-
density area by using the test chart (UKOG-0283FCZZ).
In this simulation mode, press CLOSE key to jump to the normal
copy mode and make actual copies of the service chart and user
documents. In this manner, the adjustment result can be checked.
The adjustment can be performed also by switching between the
simulation mode and the normal copy mode alternately and check-
ing the adjustment result with actual copies.
ADJ 11E Copy color balance density adjustment (each copy mode) (Normally unnecessary to adjust.)
This adjustment must be performed in the following cases:
∗ When a U2 trouble occurs.
∗ When the MFP PWB is replaced.
∗ When the EEPROM of the MFP 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 performed when the user requests it.
1) Enter either of SIM 46-10 to 46-16 modes.
(Select the simulation according to the copy mode to be
adjusted.)
