Clear Tech Rep Faults

The following printer faults can occur during normal operation, and the normal
procedure is to isolate and repair the problem. However, with these particular
faults, an additional step is required. A value has been written in the engine
NVRAM that requires clearing before the printer can be used. Some faults require
three occurrences before the fault is generated.
Note To clear a Tech Rep Fault, you must disconnect the Finisher
option.
The following functions generate a Tech Rep Fault:
Belt Home Too long - Error: 30
