ABSTRACT:
A fault protection system for impression devices of a printer detects fault current in the impression devices during non-print operation, checks the impression devices individually to determine the location of the fault and then disconnects the impression devices from the power supply. The fault protection system also includes means for recording the fault location data in a storage means which can be called out for later use in repairing the impression devices.
