Have a machine with about 3.2 mil. Have replaced everything I can think of and made adj. but I can not seem to get the lead edge to come out nice and crisp. It is washed out like the T/S charger comes on too late. Have adj tfr on/off timing and trail edge. Tried reg adj also. Has new pcb and t/s assy. pre tfr lamp also ok, new drum and m/c. Any other ideas.
