Where is the main charger Unit
1. Check and clean the main charger, replace if required.
2. Check and clean the transfer/sep. unit, replace if required.
3. Before you replace the HVT board, check HVT connector bracket (the black color plastic piece mounted on the machine frame where the main charger connects). If this part is damaged or cracked, the high voltage will arc through this, which can cause C970. (found in several machines).

C970:
HVT or charge corona.
Remove main charge and trans/sep. coratron units and check --- make sure wires are not broke, clean grid, clean canals of units.
Replace and part needed.
If coratron units are fine --- replace HVT ( high voltage transformer).

C970 indicates charging issue. Need to check the T/S block and main charger for deform/broken wires.

Call a Service tech
Have him reset yor Counter AFTER he over checks your copier and inspects the Drum,.Transer Unit, and Fuser Unit chances are the previous tech may not have reset the counter
but call for Service to verify those parts are good first ok. I would not want a counter reset to occur if a fuser unit is bad or something. At that low copies it maybe time for corona's to be replaced.
