I have cleaned out and serviced this mc, trouble is the copies are feint, tried new drums and transfer belt but still the same trouble, anyone else had this problem?

Four possibilities come to mind:
1) Broken alignment pins on one of the the developing units where it slides in.
2) Poor connection at the contact set where the developing units slide in. (Loss of developer bias).
3) Blown HVT (on the power supply)
4) Bad engine controller.

In that order. Hope for #1 or #2. They are relatively inexpensive.

Cheers for the reply, its not the pins as i have replaced all the dev units, all the contacts seem to be touching and this affects all colours, not just one. im suspecting a bad controller, i will try to swap it for another from a spare as the hv board is a bit labour intensive to replace.
