Electrical Troubleshooting

Electronics Module

The Electronics Module contains the power supply, main board containing the image
processor controller board, and the power control board. If a component of the
electronics module fails, and service is necessary, the entire electronics module is
replaced as a unit, with the exception of the NVRAM, memory, configuration card,
and hard drive; no individual board troubleshooting is needed. The system contains
many self test routines to aid in diagnosing problems.
The system backframe contains the scanner and exit module power supply and the
scanner control board.
Note
If the system encounters certain fault conditions, the system may reboot up to
three times before displaying an error code. This is an attempt to correct the
problem and reduce the number of unnecessary service calls.
Following the suggested troubleshooting procedures in the specified sequence
generally provides better test coverage than performing tests in a different order.
If either the scanner turns on or the exit module initializes, the scanner power supply
is operational. If the scanner turns on, but the exit module doesn't initialize properly,
then the power supply may be operational, but the exit module board may be
malfunctioning.
Note
The image processor controller board enables the scanner power supply and
communicates with the exit module, scanner, document feeder, and control panel.
A faulty image processor controller board can make it appear as if other
subsystems are not working properly.
