Does this streaking problem occur when printing (not copying)? If it does then you are probably looking at a consumable issue. Alot of times black streaking is caused by a defective or spent drum. Is your drum new? There is also a blue piece on the drum unit used to clean the corona wire that cleans the drum. Have you tried moving it back and forth several times?

If the problem only happens when copying and the streaks are as bad as you make them out to be then you problem have a bad CIS unit (scans your originals for faxing or copying)

Why is there a black line on copies when pages scanned with automatic document feeder but fine when using the flatbed scanner?


Different paper path, the MultiFunction unit is dirty - Most likely toner inside the roller or paper path. Try a laser cleaning cloth that you can buy in some stores or online. Search: Staples

DIRTY COPIES BOTH SIDE OF PAPER


don't always believe what they say. just because its "supposed to " last a certain amount of time, doesn't mean it will. Once you get the insides dirty, its hard to get them straight again. Sometimes there is build up on the printer head from a leaky cartridge. I'm just guessing cause I had a similar brand that was brand new act up on me and because I was printing bold it started rolling the paper. I put it on economy printing to save toner and after a few runs, it cleared up. plus using a watermark helped but don't think that will help you in your situation.
Sometimes when I get a streak on one side its from light coming in from somewhere and it thinks its part of the image and prints it. If you make sure that your material is flat and not allowing light to come in or its firmly against the glass it might help.

My brother MFC 8500 is receiving alright but everything I send out has a big black streak going down the right side of the page. Confirmation page also has big black streak.


Let me see if I got this right.

The received fax is clean but when you send one out it has a black streak on it.
Cool! So far so good.
Makes sense because for sending, the fax scans the original document and parts of the scanning area could be dirty and so on. Therefore a black streak may appear.
The same black streak would also appear when you make a copy, because the original document must also be scanned.
Logical!

However for receiving faxes, the machine uses the internal memory and the print engine only, and the same applies to printing the transaction report, which comes from inside via the print engine.
The scanner has no rol in either situation.

Now I'm lost!

Vertical Lines through incoming faxes and copies.


Sometimes you may see vertical streaks/black lines
on the faxes you receive. Either your FAX/MFC's
primary corona wire for printing may be dirty, or
the sending party's fax scanner may be dirty. Clean
your primary corona wire (see pages 13-18), or ask
the sender to make a copy to see if the problem is
with the sending machine.
Cleaning the Drum Unit
We recommend you place the drum unit on a drop cloth or large piece of
disposable paper to avoid spilling and scattering toner.
1 Carefully turn the drum unit upside down.
2 Clean the primary corona wire inside the drum unit by gently sliding the tab
from right to left several times.
3 Return the tab to the Home
position (  ) before
reinstalling the drum unit.

THERE ARE LARGE STREAKS OF INK ON ALL COPIES AND


The green roller is the drum which has a cleaning blade to remove excess toner, when the drum gets older it becomes clogged and will dump toner back out onto the drum. Just some info on it. Best fix is replace the drum, you could take it apart and attempt to dump and clean it but it's rarely worth doing that.

When printing dark line down copy


A line down the copy can come from a dirty document scanner lens.
Usually white out or wet ink will smudge on the document scanner. Opening the document cover check the scanner for a dirty glass. Some document feeders have the white roller on top of the small glass window. They have delicate plastice retainers that hold the roller on both ends. Extra care needs to be taken if this roller is removed.
Clean the roller and the glass with wet towel. Shine a flashlight on the glass to see if there are anymore black marks on it.
Use the finger-nail to run across the glass and make sure no debris is on it. Even a spot can make a line on the copy.
Also, a bad fuser roll can cause a black line on the copy. A defective drum unit can cause a line on the copy as well.
If all else fails place a Xerox service call for this problem.

Papers come out with black streeks on them from my sharp FO 4450


If everything is coming out with streaks, it's most likely your cleaning blade which is part of the drum cartridge. I've also seen this from 3rd party toner. Get Sharp toner for your Sharp fax if you don't have it already. If your black streaks are only on copies and sent faxes, this indicates that your scanner is dirty. It's located where you feed your paper in. Lift this part up and you'll see a strip of glass running front to back about 1/2 inch wide. Clean it and that will get rid of lines.

I have a black streak all on one side when i copy ?


If it is just when you copy and not when you print then it is a cleaning issue. Toner cartridge would cause the line to appear on copies, printouts and faxes. There is a piece of glass inside the auto document feeder that is probably dirty. Open up the document feeder as if you were clearing an original document jam. Look for a piece of glass inside the ADF, it will run the length of the document feeder. There is probably some dirt or another popular problem is white out. Clean off the glass with glass cleaner or alcohol and it should fix the problem.

On the konica 2223 when printing it leaves a dark thick line down the center of the paper.


Konica 2223 copiers are analog meaning the image that comes out on copies is a direct reflection off of the copy. Dirty mirrors in the optic section can cause a dark band, but it is more of a shading effect. Drum assembly's can be removed.The image drum has a cleaning section that uses a urethane blade to clean excess toner off of the drum after the copy passes through.It is simply called a "Cleaning Blade" these blades can be ordered through most online copier part stores. Last but not least is the "Upper Fuser Roller". this is the hot roller the paper passes through to "set" the toner to the paper. These are coated with teflon to prevent toner from sticking to them. They have "seperator claws" that keep the paper from adhereing to the roller, and they sometimes gouge the teflon. this exposes bare metal, and the toner can come off of the copies and stick to the roller.

Large grey streak down center of page


It is the fuser at rear giving you grief! The upper heat roller has a teflon coating that wears away allowing toner to stick to roller and smudgin prints as they pass threw it. The fix is to replace fuser assembly, take to brother dealer to fix.

You can prove it to yourself by timing the print to stop mid way threw machine then remove print cartridge and look at paper, you should see a image is good untill it hits the fuser,( pre fused image "rubs off" paper.) If you have changed drum and toner thats all it can be. They all do it in time.

Fuser is hot bit at rear, pull out drum and look in the back with a small torch you will see upper heat roller is worn, guestimation $90 for fuser plus labour to fit.
