The back side leading edge has toner on it and fades out as you get to the trail edge. if you run multiple copies it is only on the first copy. I have noticed that if you look at the drum prior to making copies there is a coating of toner on the drum. It appears that the toner is getting on the transfer roller and then the back of the paper. Have tried a different High voltage board and SBCU board with no change. Have also shorted the drum ground with no change.
Did notice that when you take a meter reading from the high voltage board the drum charge does not get to 1650 volts as fast is it did on a machine without the problem. Any Ideas or suggestions. Thanks
Dennis
