Brother MFC 6800 printing blank pages after fuser, toner, and drum was changed

I have a Brother MFC 6800 printer. The printer had light vertical places on the printout. From past experiences, this has been the fuser. I changed out the fuser and it only prints out blank pages now. No toner is on the page. I put the old fuser back in and it does the same thing. I changed out the toner cartidge and drum. Still printing blank pages. Any suggestions???

    by the way...check the board conectors of the fuser...maybe you need to clean this little board down the printer....under a plate
    check it..if you move before....

    i think , in my case ..this is the really problem of the blank page....a bad polarisation or contac....but i dismounting to many times the covers...so i break the soldering of the regulator..(the stepper supply voltage..)

    i have many experience working whit hp equipments , since i work whit a hp dealer...and this problem in hp ,,is the same...a bad contac of high voltage....

I have a Brother MFC-7340 and recently replace the toner and now the background is dirty looking when I print, ie grey where it should be white! What can I do to clean it up? Thanks!!


Either you purchased a a bad quality remanufactured toner cartridge or your fuser film is damaged.

If there is some kind of debris in black color that is on printouts, your fuser film might be damaged. Have a printer technician replace it.

If there is no debris, only bad quality printouts, it's the toner cartridge that needs replacement.

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.

Printout from Brother MFC8460N has vertical faded line across page


Try replacing the toner and if it still happens then you have a bad fuser. But im pretty sure its a faulty toner.

Black Vertical line on copies using MFC-8660DN


Vertical lines mean it is being caused by one of the rollers within the printer. This is usually either the toner cartridge or the fuser assembly. I would try changing out the toner cartridge first even if it is new as sometimes they are DOA and they are much cheaper than the fuser assemblies. If that doesn't work, probably the fuser assembly.
