20-L Color document identification level (ACS
operation) setting
When the machine is used with some adjustment values changed
from the default values, this adjustment is required in the following
cases.
* When a U2 trouble occurs.
* When the MFP PWB is replaced.
* When the EEPROM on the MFP PWB is replaced.
* When the user requests for the adjustment.
This setting is used to set the recognition level of a color image in a
document.
The actual ACS operation is executed according to the combination
of the judgment reference value in the color auto mode set by the
device and this setting.
When a monochrome document cannot be judged as a mono-
chrome document or when a color document cannot be judged as a
color document, change this setting. This setting is applied to the
color auto copy mode.

2) Select the ACS mode with [NEXT] key and [BACK] key.
3) Select the setting mode of "P/SIM LEVEL" with the scroll key.
When a monochrome document is not recognized as a mono-
chrome document, increase the set value.
When a color document is not recognized as a color docu-
ment, decrease the set value.
After entering the set value, press [OK] key to save the set
value to the memory.
The figure in the table indicates the ACS setting level in the
device setting.
The ACS setting level of the device setting (the judgment refer-
ence value in the color auto mode) is changed with the setting
of SIM 46-33 ACS/P/SIM LEVEL.
The left and the upper area from the cross point of the device
setting on the table and the ACS/P/SIM LEVEL setting serves
as the ACS operation condition.
