Unisys Laser Printer

[boxtop]

I've got a Unisys 9510 laser printer. It's a nice old machine, but lately it will not feed the paper all the way through. The paper partially feeds through and then I get an error message (28) that says to load more paper. I have to press "continue" and then the paper finishes its cycle. Does anyone have an idea what the problem is?

Try cleaning it, that usually works. Use alcohol and clean the rollers, maybe get some canned air and blow it out. Use a REALLY soft and lint free cloth (perhaps a tissue, dont scratch it either) and softly dust of the drum.
