I'm pretty sure this is a printer not a copier.

Take out the cartridge and turn it upside down, you will see a (Usually) green cylinder, does it have a ring of toner, or does it appear to have been scrathed ?
Take the copy and put it next to the drum, does the lines match? Then replace cartridge. 
If not open back and take out fuser ( two screws for cover and two screws for fuser, are the rollers o.k? replace fuser.

Copies come out with dark streaks

Looks like a dirty, scratched or contaminated drum. Try wiping the drum with a very soft cloth, the streaks should go away but may re-appear. If there are visible marks on the drum that cannot be wiped of with the cloth, the drum will have to be replaced. DO NOT TRY USING ANY SOLVENTS TO CLEAN THE DRUM.

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

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.

Black blotches and streaks on copies

Sounds like a worn drum unit primarily the cleaning blade on the drum is failing. If you don't change it out soon the dirt escaping from the drum and dirty copies will foul-out you fixing unit, = more $$.

Looking for a service/repair manual

At minimum, the drum and cleaning blade need replacing - possibly developer as well. I'm sure the optics are dirty, as well as the charge and transfer corona.

Intermitantly streaking copies

Sounds like the wiper blade in one of your cartridges has failed. Try swapping cartridges and see if this helps. The problem could be with only one of the cartridges, so try changing one at a time to find which one is causing the problem

Streaks on copied paper

You have a failed drum cleaning blade that lives in the drum cartridge. The blade is replaceable as a seperate item.

Streaks on paper

Nisha... If you haven't done so already, you need to run a few copies off the glass as opposed to through the feeder to determine "where" your problem is. Do the copies of your originals placed on the glass have the same line/streak defects as the ones made run through the feeder? IF NOT, then you probably have some sort of dirt or contamination on the FAR RIGHT side of the glass (ink, white-out, dirt, etc), and the machine is reading that as part of the image and printing it as a line. When running copies through the feeder, the scanner moves to the far right and parks there. Then the feeder moves the original over the scanner on the right side of the glass (the scanner stays still). So if you find the lines evident when using the feeder, but not there when copying off the glass, you need to clean the glass on the far right. IF YES (lines/streaks through the feeder AND off the glass), then your problem is most likely internal of the machine (bad drum in the L50 cartridge, dirty optical scanner, worn fuser rollers, etc) and I hate to say it, but will probably require a service call to rectify it. Sometimes you can actually take the L50 cartridge out immediately after running a few copies, and while holding it up, manually open the spring-loaded drum shutter on the under-side of the cartridge to expose the drum and visually inspect it to see if the line defects on your copies are evident on the drum itself. If so, you will most likely need to simply replace your cartridge and hopefully save a service call. If you can't really tell if the streaks are on the drum itself, then you're back to probably needing a service call. NOTE: DO NOT TOUCH, WIPE, CLEAN, OR OTHERWISE CONTAMINATE THE DRUM WHILE YOU ARE DOING THIS, and do not leave the unit exposed to light for longer than a minute or so, because if the problem isn't evident/obvious with the drum cartridge, you don't want to risk damaging/contaminating it and thereby causing one. Please let me know if any of this was helpful. Thanks.
