Phaser 7100 prints black marks



Our Phaser 7100 has started printing black marks on pages quite randomly.


We've recently changed the black imaging unit and toner and have run several pages through the printer. Everything is fine for a while then we get a pages with black marks and streaks.IMG_2486.JPG


We need to replace the C, M & Y imaging units soon.


We've cleaned everything we can find instructions for - we'd appreciate some ideas about how to fix this.

Re: Phaser 7100 prints black marks


Take a look at the Black Developer Unit (under the Black Imaging Unit) if it not loose toner. If it is so you must replace it.
