Regist Sensor - Canon imageFORMULA P-208 Service Manual With Parts Catalog

4. Regist sensor

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 registration sensor operats cor-
rectly.
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 control PCB on which the
sensor is installed.
This mode is included in "All" 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 Adjustment screen, select [Regist
sensor].

3) The adjustment starts automatically and
ends instantaneously.
Note: A progress screen is displayed, but it
cannot often be confirmed because it
is displayed instantaneously.
