18.2.4.3 Adjustment of the ACS identification level

imageRUNNER C1022 / imageRUNNER C1022i
When using the auto color selection function (ACS mode) with ADF, the machine may misidentify the black/white original and the color original depending on the
statuses and types of originals.
On the assumption that the maintenance service contract will be made with customers, the value of identification level is adjusted at the factory in advance to prevent
the extra charge due to the machine erroneously identifying a B&W original as a color original. And in addition, the additional functions mode is hidden to prevent
the customers from changing the identification level.
Following is the procedures to adjust the identification level to prevent the machine from identifying a color original as a B&W original upon user's request etc.
1) Enter the service mode. (main menu > 2 > 8 > main menu)
2) Change the value of the following service mode item from "0" to "1".
COPIER > FUNCTION > PARAM > DSP-ACS
3) Turn OFF/ON the main power switch.
4) Change the following additional function mode setting.
Select: Additional func. > Adjustment/Cleaning > ACS Function Adjustment > Feeder, and change the value by 1 scale toward "color priority" side.
5) Enter the service mode. (main menu > 2 > 8 > main menu)
6) Change the value of the following service mode item from "1" to "0".
COPIER > FUNCTION > PARAM > DSP-ACS
7) Turn OFF/ON the main power switch.
Following is the service modes and the additional function modes related to the ACS identification level adjustment.
- Service mode: COPIER > FUNCTION > PARAM > DSP-ACS
To display/hide the additional function's items:
0: Hide (default)
1: Display
- Additional function mode: Additional Func. > Adjustment/Cleaning > ACS Function Adjustment > Feeder
