SOURCE: vertical single black line on printed pages - does

The first thing I would try is to fix the corona wire. Here is a link to Brother's website outlining the process (clean corona wire).
What you need to do is pull out the drum and look for a blue tab on the top of the cartridge. Slide that tab back and forth along the wire and see if that clears things up.
I have had some luck cleaning the drum when I get black streaks but I have also hear this can be dangerous and make the problem worse.

Brother HL 2240 ready light it on, call for print but nothing happens.


if you press the GO button 3 times very quickly (1-2-3) and you get a printout from the printer then the most likely reason is problem with the connection or the windows driver

IF YOU HAVE A SOLID BLACK LINE RUNNING VERTICALLY THEN YOU HAVE A FAULTY MATRIX INVERTER. IF CENTRAL THE MAIN VERTICAL INVERTER NEEDS CHANGED. LEFT = LEFT VERTICAL INVERTER RIGHT=RIGHT.........

ANOTHER WAY TO GET THIS FAULT IS WORN OR DAMAGED RIBBON/PLASTIC GOING FROM THE SCREEN MATRIX TO THE INVERTER


Hope this will help to fix the fault, do take care in handling the solution

Black Vertical Line on the paper


start a print from tray 1/manual feed and just as the trailing edge of paper is entering the machine;quickly open it to stop print and take out the cartridge and look at it's drum and the paper underneath. if the issue is there at that point then it would point to the cartridge. if not then the fuser
Let me know....
If I could be of further assistance, let me know. If this helps or solves the issue, please rate it.

MY brother HL-5140 quits printing,and also has a black vertical line down the page before it quits. After a while, say 30 to 45 minutes, it will start printing again. But there are black smudges on the...


Sounds like a fusing error ... If your able to wipe the toner off the page its a fuser unit problem (replace fuser unit) If toner is sticking to paper but the print quality is poor , replace the drum unit  (PCU)  good luck

Did you mean 'vertical' (from top to bottom) line rather than horizontal? If it goes 'straight down,' it has to be. I think so, otherwise the added info that it is closer to the right wouldn't make sense.
This problem is normally due to contaminents on the surface of the drum itself although can also occur if a wire that discharges the excess toner from blank areas could be dirty.
Changing the drum cartridge will correct either of those problems since they are contained in the drum cartridge. If you are using 'recharged' cartridges and it only has a few copies on it, most companies will exchange it for you.
