MFC-9440 CN--Lines in my auto feed scanned/faxed copies

My 5-month old 3-in-1 makes perfect copies and scans when I do a single page on the glass. However, whenever I use the auto feeder (photocopies, faxes or scans), I get 4 or 5 lines, from the top to the bottom of the page, about 1.5" from the left margin. This problem has persisted from when I bought the printer, through changing out all of the toner cart cartridges (including the cleaning that you do by moving that plastic tab back and forth several times, then returning it to its original position).

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.

Original document fed into top feed tray of mfc 7440N model come out with few thin black lines on the mid left of the scanned file. Scanning file from glass has no issue.


You need to clean the narrow glass strip on the left side of the machine when you open the cover. There is likely lint or something on this glass. This is where the auto document feeder pages are "imaged".

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.

Print Problem - vertical lines


If the problem only occurs when using the document feeder, the problem is not usually caused by the drum. When using the document feeder, try to notice where the scanner (the light assembly under your scan glass)stops just before the paper is being fed. Some multifunction machines have a small piece of glass that is separate from the large scan glass and the scanner assembly stays parked underneith it as the original is being fed over it. Most likely there is something on the glass where the scanner parks as originals are being fed thru the feeder. When putting your original on the large scan glass to copy, the mark on the glass will only show as a spot, but will show as a vertical line thru the whole copy when using the feeder.
