Customer calls in for "copies have light background. After cleaning up overtoning issue, determined it needed a developer change. 175K on Dev/PM. Performed ALL procedures in manual after Dev. change, also replaced blade. Ran a few copies it looked great customer was happy, I left. 200 copies later she calls back complaing about background again. Upon closer inspection when I stop copy half way I can see on the drum a very light toner covering the drum. I have tried to change Charge voltage, Grid voltage and Bias to no avail. What else could it be? Many Thanks, Bill T..
