Description
The scanner does not return to home
I
position after it has started to move.
Activation of the lamp has been de-
I
tected during stand-by.
Deactivation of the lamp has been de-
I
tected during copying.
An error has been detected in the
I
communication between the DC con-
trol PBA an the image processing
PBA.
An error has been detected in the com-
munication between the CPU on the
control panel and the image processor
PBA.
The intervals of zero cross signals are
outside the allowed range.
The communication is monitored at
I
all times. This error is identified when
the communication with the copier is
interrupted for 5 sec or more.
A vane is fitted to the shaft of the
I
pick-up motor M1. The rotation is
monitored by checking the passage of
the vane past the sensor S5. This error
is identified if S5 is not switched on
and off twice within 1 sec.
