Graphic Design Forum :: Xerox Phaser 7700
We have a Xerox Phaser 7700 that prints a yellow line on both sides of the paper from time to time. I can't figure out why it happens or how to stop it. We just changed the fuser and the waste toner cartridge and that didn't make any difference. It will stop as abruptly as it starts. Can anyone help with this? - Read More at This Link..
