Purpose Adjustment
Function (Purpose) Used to perform the light quantity adjust-
ment of the process control sensor and the
registration sensor (two for resist are
adjusted simultaneously) and the surface
scan.
Section Process
Item Operation
Operation/Procedure
1) When [EXECUTE] button is pressed, it is highlighted and all
the drum motors are driven to start the adjustments of the pro-
cess control sensor and the registration sensor.
* After completion of the adjustments of the process control
sensor and the registration sensor, the drum motors are
stopped and the set contents are displayed. The necessary
data are saved to EEPROM.
[EXECUTE] button returns to the normal display.
* When [EXECUTE] button is pressed during adjustment of
the process control sensor and the registration sensor, the
monitor is terminated and the drum motor is stopped. [ECE-
CUTE] button returns to the original state.
Data saving is not performed, but the result at that time is
displayed.

* When an error occurs in the adjustment, "ERROR" is dis-
played in the value display section at the right of the error
item, and the drum motor is stopped. Data saving to
EEPROM is not performed at all and the operation is termi-
nated. [EXECUTE] button returns to the original state.
* When there is a page over [↑], the display becomes active
and shifts up to another page. When there is no page over
[↑], the display grays out and the operation is disabled.
* When there is a page under [↓], the display becomes active
and shifts down to another page. When there is nor page
under [↓], the display grays out and the operation is dis-
abled.
<Operation content>
1) Adjust so that the LED light emitting quantity of BK/CL is the
target value ± 2.
* Target value
BK: Item B of SIM 44-04
CL: Item A of SIM 44-13
2) After completion of the adjustment, check the belt surface con-
dition with the BK sensor.
