Vertical lines


Lines in prints with this machine would suggest a fault with a drum unit. As each toner cartridge contains its own drum unit it is likely to be a particular colour at fault. If the colour is not immediately obvious, I would recommend printing off a test page like the one here:

Brother MFC-6800 1. Prints with 3/8" blank vertical line down the entire page; 2. Prints with a couple of 1/16" blank vertical lines down the entire page; 3. Prints with some gray shadow...


This solution is unconventional but it worked for me. The black roller on my MFC had irregularities on it and was creating horrible printouts. I pulled out the drum and cartridge and cleaned the large black roller. I used furniture polish to make the roller very smooth. Now it prints really nice.

LCD monitor have Vertical lines and black colour become greenish


normally the 19" resolution can support up to 1280*1024, but if it comes with vertical lines in full screen, it might indicate the panel is no longer to work and probably it's time to replace new one.

Black colour displaying become greenish and narrow vertical lines


Most LCD monitors have a default refresh rate of 60 Hz. Older monitors also have limited resolution. Please check your display settings and ensure you're not using a refresh rate higher than 60, or a resolution higher than what it supports. If either one is the case, you're lucky the LCD still works.

Light or Faded Areas in Solid Color Prints


If the issue is occuring in the same place on all prints, try the imaging drum (can't remember if this printer even uses one) or the transfer belt/roller (not sure which it uses). If you phone Dell support, they should run you through troubleshooting and send you either of those parts free of charge if you are under warranty. If not, buy them anyways; they don't degrade over time (if kept in the dark) and can be saved for when the currently installed one runs out if you don't need it to fix this issue.

Ink gets carried over to subsequent sheets


More than likely your maintenance kit roller has been impacted with ink and is not applying enough lubricant to the drum. You can replace the maintenance kit and run cleaning procedures a couple of times to allow it to clean up.
Now the other issue is if you are using a third party ink stick. By that I mean non xerox brand ink sticks. I have seen those cause that problem more often than not.
Pull out the maintenance kit and see if the large roller, which should be a off white, is black.
Exacly what is happening is your maintenance kit puts a very thin film of silicon oil on the drum so that the ink does not adhere to the drum more than normal. When that roller becomes blackened, it isn't very effective and you get some of that residual imaging.

Vertical streaks


The toner forms small lumps and get stuck on the doctor blade of the cartridge. Where there are the lumps it blocks the toner from getting on the roller. Removing the doctor blade and cleaning it with a soft cloth and alcohol can solve your problem.
Send me a mail at ecoworld@myt.mu if you need further help in doing it.
