Question about Xerox Phaser 8400 Laser Printer
The printer is producing a distorted, sort-
of smeared document tht cannot be read. Help I just spent $600.00 on ink!!!
If you remove the right side cover, locate the drum shaft about midway back and midway up.
There is an encoder on the end of that shaft. Remove it and clean it with some alcohol. Don't be afraid to flush it a few times. Let it dry and reinstall it. It get's contaminated with the silicon oil from the maintenance kit and causes a very blurry print because the drum runs the wrong speed.
That may need replaced, but the vast majority of the time, cleaning the encoder resolves that problem.
