AR-C170M  PRINTER CONTROLLER SECTION  14 - 18

1: When set to enable, the easy calibration, test print, and color

balance cannot be performed in the color adjustment of printer
setting of key operation. 

(Items to be selected)

*1: When SIM 50-20 is used to adjust the image resist to the best 

and the image resist adjustment is performed under the 
following condition automatically, the best adjustment state 
may be changed. To avoid this, set the adjustment item AR to 
Disable.

When the adjustment item AR is set to Disable (ON), the 
image resist adjustment is automatically performed under the 
following conditions.

Normally set to ON condition.

*2: When the image registration automatic adjustment operation 

is abnormal, it is judged as an error or not.

• After replacement of a toner cartridge

At every 8000 copies (total of print and copy)
(When, however, 8000 copies is reached during a job, the
operation is stopped after completion of the job.)
