Gray tinge on Xerox 5260 Copier

"Earlier this year, I inherited a Xerox 5260 personal copier. It works well except all the copies have a grey tinge to them, even when the auto-exposure control is set to light. The grey background is visible over all the page, and gets noticably darker when the auto-exposure control is set to dark. Is it time to replace the copy cartridge?"

(From: Lionel Wagner (ck508@FreeNet.Carleton.CA).)

Your toner/developer wheel bias voltage may be wrong. When light strikes the photosensitive drum it does not completely discharge it. The toner/developer bias voltage must precisely match the residual charge or grey background will result.
