6. Regist sensor adjustment

This mode is used to adjust the initial
value of the quantity of light received when
the document is not set at the sensor section
so that the regist sensor functions correctly.
The value performed at the factory is set
when the sensor is shipped from the factory,
but the adjustment is carried out if the regist
sensor does not detect a document correctly
because the ambient amount of light is very
different and so on. Also run this mode after
replacing the start switch PCB on which the
sensor is installed and after replacing the
control PCB on which data is stored.
For this machine, the card sensor is also
adjusted. The LED and light-receiving sen-
sor for the card sensor are mounted on the
upper FPC.
This mode is included in "All Adjust-
ment" described later.
Operation Procedure
1) Clean the surface of the light guide for the
registration sensor.
Note: Do not set the adjustment sheet.
2) On the service screen, select [Regist
sensor adjustment].
