Hello There,
I have a Image Class MF838Dcdw printer and after being idle it will print about 1/2 inch horizontal black band on the paper. It does't matter if the paper is coming from the tray, paper feeder, or the bed. If the machine is idle and then starts to print, there will be one or two horizontal black bands on the paper. If I make another copy, right after the first copy, then the horizontal streaks are no longer there. I've tried changing the cartrages, cleaned the fixing unit, ITB, and feeder and none of this seem to work. Any suggestions on how to fix this problem?
