It sounds like you're scanner is shot

Check carefully the glass, a very small point of ink or anything else can cause the black stripe. usually  it is that the problem. use windex to clean it.

The faxed copy has a big black line in the middle of the paper. A new toner and a new drum have been installed but the line is still there. Help! Ruth


Clean the scanner glass. This is the smaller piece of glass that is located just to the left of the large original glass. Or if you have an older or smaller model Brother the strip of glass is going to be located under/inside of the port where your documents are fed into the machine. This operation panel usualy just pops open and you can find the strip of glass inside. Just clean it with a bit of glass cleaner that has been sprayed on a soft cloth. Make a copy with the machine to test if the line is gone. If the copy mode comes out ok then your outgoing faxes will be ok. You can also make a copy before you start the cleaning process as the copy with the line on it can aid you in determining what area the glass needs to be cleaned.
Good Luck and Thank You for using Fixya.

Copy and faxes come out with a black line on the left side about an inch from the side.


If your INCOMING faxes have the same black line as your copies then the problem lies in the toner cartridge. A line on OUTGOING faxes and copies would suggest something on the scanner glass. This is a small strip of glass under the cover where your originals are fed into. Another way of testing is to run a report from the operation panel. If a report generated from the machine is ok then it is the scanner glass. If the report has a line then it is in the toner cartridge.
Good Luck

Leaving a wide black line in right hand side of transaction


Pop open the fax document feeder, and look for a glass strip about 1cm wide, that runs from left to right across the machine.
You will probably see a few spots of dirt, or more commonly, a blob of white liquid paper stuck on the glass, on the side of the machine that corresponds to the black lines on your fax.
Clean this glass strip gently, using a soft cloth dampened with a mild detergent. I often use diluted windex. You may need to scrape liquid paper gently with your fingernail. Close the cover.

Next, put a blank sheet into the feeder and make a copy of the blank page. If you have cleaned it properly, the copy will be blank as well. If you still have a line, align it with the feeder and use this as a guide to show you where the glass may still have some **** stuck on it.

Good luck!

Black lines in copies and fax's Brother MFC 7420


If the black lines comes when using the ADF (top feeder), try to see if you get the same problem when using the scanner glass or receiving faxes. If you don't, you simply have to clean the glass strip to the left of the a4 sized scanner glass. Wipe it with a dry cloth piece, no paper and no water/alcohol. If you see some dirt there that you're unable to simply wipe off, try to use a cotton wool to "rub" it off.

1-en front door look inside and see if there are black rings around the shiny Drum cylinder, if yes replace drum blade (may have to replace drum also).

Right side of faxes (or copies) have 1-1/2" black line


Try changing the Drum Unit again....it cannot be anything else besides a worn out drum cleaning blade.

Inch and a half black line down page


not sure what model fax you have, did not specify.

1-check to see if there is a white metal plate opposite the glass.
is there any toner or dark marks on it ? clean or use white out to cover make sure it is dry before using.

2-check the black spongy roller inside the machine

3-it maybe that you have a two unit cartridge, one for toner one for the drum ( which is what it sounds like) pull out and check.
It should be a shiny cylinder, does it have a black ring around it?

4- the last thing to check is the fuser, on its way out of the fax it passes two rollers on on top of the other, it may be a little difficult to see, may have to remove a cover, how do they look?

Copies and outgoing fax quality


your machine most likely has toner spills in it.
if you send faxes face side down follow these instructions ;
1- take out toner
2- look for thin glass strip on bottom inside the machine
3-wipe clean

if you make copies side up then do the same except look for glass strip on the upper side of machine

BLACK INK LINES ON INCOMING FAXES KX-FL511


It's time to change NEW DRUM UNIT..and that's why your Toner will Not Last Longer because unnecessary toner (the black lines) will be on the copy every time the fax comes or you make a copy.
