7-7-4 Drum Counter Reset After Changing Faulty Drum (WCP 412 Only)
Operational Groups:
OmniFax (USA), NASG-Canada, ESG
Problem:
If the customer has changed their drum for a new one, the printer has no way of resetting the drum counter
to zero. This will cause problems with the future page counters if the drum has not achieved a life of 14k
copies. This facility is required to prevent drum counter discrepancies at a later date.
Cause:
There is no facility on the machine or procedure in the firmware that allowed the user or engineer to reset
the drum counter.

the machine. This can be found on the www.xerox.com website.
