My Brother MFC-9840CDW keeps jamming every time I print mailing labels. I've had it four 1.5 years with no trouble. The label gets stuck and I have to pull out the toner tray to fetch it. I also...

hello, sounds like there are many possible solutions for you machine, first with paper jamming, are labels going thru manual feed tray, or paper tray, it might be possible that mp feed roller needs cleaning or replacing. if paper tray, simple would be feed roller, clean or replace, if jams continue with normal paper from paper tray, the problem will be front door, i have yet to be able to repair paper jams when front door assembly fails. as far as colors, both drum and toner can cause this problem, if using 3rd party toner, this will also cause some color problems. sorry no real quick fix for this machine, i've tried.

I have a Brother MFC 8440..the paper has vertical black lines

Try changing the toner, if it's generic that's your problem, and if it's either an old brother drum or a generic you may need a new one. There is also a glass to clean, it's right above where the drum sits inside, 1/2 inch wide across the top. Wipe with a dry cloth.

Paper jam and 2 found springs

Those 2 springs should be re-installed, they should be put back in place in the paper guide assembly in the back they should be there to apply pressure to the feed rollers so the paper will feed.

Clicking noise with MFC-8640D

Make sure that the paper guides in your paper tray are not holding the paper too tight against the front of the tray, there should be about 1/16 inch play so that the paper can be lifted to the roller easily. Also take out your toner and drum and turn it on, if the grinding noise is gone you may need a new toner, some refilled toners are too tight to turn properly.

Paper jam

Very frustrating ... checked all over for remaining jams - but the message "paper jam" just won't go away after clearing a paper jam. Eventually, it goes away but no way to predict how long it will take!

Paper Jam - now terribly noisy!

Fuser gear cracked from the sound of it or non oem or recycled toner cart that is too stiff to turn correctly

Brother MFC 7420 Paper Jam. Paper will feed from tray to Toner/Drum then Jam. Feeds only about 4 inches of the sheet then Jams. I have replaced the toner/drum unit. Any help is appreciated. Thanks.

After changing the drum, toner and running around town for days trying to find a reliable place to get this printer repaired, I realized I was spending a lot more money than what the printer actually costs. the drum was over $100, toner was $80, and the printer is $250. I bought a new one, and I can now use the old one for parts.
