As the fax receives and prints incoming faxes ok then the print engine is working ok. the fact that the problem arises when copying or scanning indicates the problem is with the scanner or software that controls the scanner.
First clean both scanner glasses and the white area (white reference) under the doc feeder. When you are happy all is clean, follow the following instructions:
Press menu, * 2864 within 3 seconds. the display will show "Maintenance"
now press 55. The scanner will initialise and go back to "Maintenance"
now press 99 and the machine will go back to the default screen showing date and time.
Now do a copy. if you still have the lines or its all black then you will need a new contact image sensor. If all is well then that was a good cheap repair.

Black line on copy and fax functions


Clean the paper path for the scan/fax portion. The original goes in and as the document is "read" a spot of dirt is causing the black line down the page because it is picked up in the copy area.

Unwanted verticle line on fax copies


Most likely a fax has been sent or a page copied with 'white out' (Liquid Paper), still wet on the page. As the page feeds over the scanner, (a narrow strip of glass that runs across the width of the page along the feed path) the wet liquid paper comes off on the glass as a thin line and dries. Thereafter, when copying, scanning or sending a fax, the scanner light does not go through the liquid paper streak and the result when printed is a thin vertical line that runs the full length of the page. If this is the cause you will also find that faxes you send to other people will also have this line (although faxes you receive are not affected by this problem with your machine).

To fix the problem: follow the path that the paper travels when sending a fax or making a copy, until you find the scanner (narrow glass strip). Take a clean, soft cloth and a small amount of methylated spirit (or white spirit) and remove the now dried Liquid Paper from the glass. Clean the whole strip ensuring that the glass is left clean and dry.

I have a black line showing up on my faxed documents. I have opened it up, changed the film and re- set it, but the problem persists. The machine is about 5 years old.

2" black horizontal line appears on paper when I fax, print,


Check the wondow where the paper passes to be scanned. You will probably find some debris or white out stuck on the glass. That is usually the cause of vertical lines on sent faxes.

When receiving a fax I get either big black plotches all over the page or thick black vertical lines running the whole length of the page to a point where I can no longer make out any of the information...


Try making a copy of something or printing a transmission report or journal from the "reports" menu. If the same problem is apparent on these printouts, then your drum unit or toner cartridge need to be replaced

Poor Quality


If you can copy ok you have effectively ruled out your machine as you have used both the scanning and printing mechanism of the machine.

It will probably be the fax on the other end as if it sends a poor quality page that's all your machine can receive, a poor line can also cause problems if it is from multiple faxes. If so have your provider check the line (you probably hear static on the line).

Thick Black Line on my copies and faxes


Can't image it being anything but scan glass, if prints are fine, are you sure you cleaning scan glass(inside of where originals are fed)?

If so then scanner lamp faulty, but I've never come across it myself on this model.

Is this happening when you print or when you scan? If when scaning you could have something on the scanner bed... If this is happening when you print, it could be the cartride is defective.
