If you are using non brother toner then that's the problem, if not it is the drum unit.

SOURCE: vertical black line in scan document not in copies through document feeder

Lift the lid and to the left of the main glass is a smaller glass; that is what scans during the feeding process. Make sure that it is completely clean; even a speck of dust can cause a line to appear. I took a lens wipe and cleaned mine and my line was gone.

SOURCE: Brother MFC 8220 all-in-one fax prints with a vertical line

First guess is you have a bit of dirt (often white-out from people scanning corrected paper that's not quite dry) stuck on the fax scan window. This should be described pretty well in your user manual (which you can download online from brother.com).

Its also possible that there is dirt (typically loose toner) on the laser scan window (there's a laser that shines through it to get the image pattern on the drum). That window is often along the bottom of the unit under the drum/cartridge (take the cartridge out and look). The Brother manual I've seen seems to ignore this possibility.

Print streaks DO NOT mean cartridge drum replacement in many cases !! On brother Intellifax or MFC or other laser copier/printer/fax, keep in mind that either the fax/copy scan window OR the laser scan window can get dirty. If the fax scan window is dirty, you see streaks on outgoing faxes and copies (but NOT incoming faxes). If the laser scan window is dirty, you see streaks on all prints (copies, faxes, print-from-computer).

Note also that when transporting/moving some laser copier with the toner cartridge inside, the toner can get out and make a big mess inside (including getting the laser scan window dirty). An air compressor can be usefull to blow it out. And sometimes using alcohol to clean is a BAD idea (maybe incompatible with plastic and rubber parts). A damp rag is probably fine.

Brother MFC-7820N Printer--vertical lines


You need to clean the scanner glass. Also known as the strip glass. It is a 1 inch wide strip of glass that runs from the front to the back. Your documents pass over this glass when they are scanned. Some of the wax crayon probably smeared off onto the glass and now when you scan the scanner sees these marks as stationary and thus records them as solid lines. Just look into the scanner section where your documents are fed in or depending on model, some are just to the left of the large original glass.
Good Luck and thank you for using Fixya.

Depends which way is vertical but I think the feed rollers on the upper tray are slipping perhaps dirty. (The paper momentarily stops feeding past the scan sensor)
