Transfer belt unit.

Adjusted:
Voltages on hvt
Devoper doc blade/ magnet angle

Updated software.

If it happens overnight, igi may be onto something environmental being the cause. Go into SIM 44-14. It will show humidity and temperature reading in several parts of the machine. Anything odd? . Is it a foot away from the wall? If you know how to get into "super secret service mode", you can adjust the fan duties in SIM 77-23.

This thread is from April and the OP doesn't seem to have returned since... I don't expect anyone to get an answer. That's the hazard of necroing 4 month old threads...
