Black lines on copies when run thru fax feeder

When we make copies running thru the fax/ copy they come out with 2 black lines on each side of the paper about 3" from the edge. What is this coming from?

    When I run a paper through the fax/copy feeder upon completion the copy has 2 black vertical black lines running from top to bottom. I replaced the imaging drum and a black cartridge. The lines are still there.

There is a thin strip of glass that you will see when you lift the top feeder. There is most likely white-out on it.

When you use the top feeder, it doesn't use the large glass, it only 'rolls' the original document over this small strip of glass.

Getting thick black line on edge of paper on all faxes coming thru


If it is just on faxes you are receiving and not on ones you send it sounds like it may be your drum. You may have a small tool in the fax to gently rub across it and clean it. check your manual to make sure. In worst case scenario you will have to get a new drum. Look on line for your model. Other wise if it's on copies and faxes you send as well it's going to be the thin piece of glass right where the pages are being feed in that needs to be cleaned

Horizontal black and white lines are coming on copy


you don't mention whether the document you are copying also appears on the paper.If it does you could have 1 of 2 problems-
The drum cleaning system could be at fault or-
the fuser roller has picked up some **** easy test...... run copies and when the 1st copy edge appears switch OFF. This is a crash stop.Now examine the sheets in there.Is the stripe on the copy before the fuser (Heat) roller? If yes you could have a drum cleaning problem, usually fixed by changing the drum module.If no and the stripe appears after the heat roll, the problem is with the fuser system,dirty rolls etc. There are a number of other problems with stripes, but you have to start somewhere! If the document does NOT appear on the copy, forget all above, could be scan or ROS problem
