Question about Brother MFC 7420 All-In-One Laser Printer

1 Answer

My brother 7420 MFC has been getting rear paper jams and constantly says to "change drum soon" or "dust on Drum". I don't want to waste money on a new drum if the jamming and "dust on drum" messages are going to constantly slow me down. Any suggestions?

Paper jams brother mfc 7420


Paper Jams are routinely caused by bad roller in the printer. The Heat of laser printers can render these rubber roller pretty useless in a couple of years or less if you print often. If you have recently replaced the drum (according to the recommended print output number), Then If an $80 dollar roller + labor is worth it to you, go for it, otherwise buy a new printer and Brother gives the best ink value per page. hope this helps.

I have a paper jam in my MFC -7420. I removed a sheet from the back but there is more stuck in the front. The message says to open front cover and remove drum. I have opened the front cover but...


Don't try to remove the drum by itself while it's still in the machine,
just simply remove the drum and toner cartridge together.

There is no lock you should just be able to pull the cartridge out.

Brother MFC 7420 change drum soon light, did, still says change drum soon, how do I rest the drum, I cannot find my manual. Tks


Simply open the front cover.

Press the Options key on the control panel.
The display will show "REPLACE DRUM - 1.YES 2.NO".

Press 1 to reset the drum count.

Close the front cover.

This procedure wil work on the majority of the Brother MFC series of laser based Printer Scanner Fax Facsimile machines.

Good Luck and Thank You for using Fixya

My drum is dusty. How do I get the dust off?I have an brother mfc 7420


Dust on drum is an issue with the corona wire. Use the blue tab on top of the drum unit. Slide it back and forth 10+ times and this should correct your issue.

Brother MFC 7420. New Brother Toner, New Drum, cleaned feed and separator rollers, changed paper, still jamming. Paper stuck around brown fuser roller. What can I do next?


Check whether the fuser rollers are free turning. If the paper is stopped at the ejection roller, the ejection roller needs to be replaced.

MFC-7420 "Change Drum Soon" I have had this message for a while. I purchased a new drum. In the meantime the printer continues to print fine, except we have paper feed problems. Is the drum related to...


the only time i've seen the drum affect paper feeding is if paper jams in the drum unit. i would use your current drum until print quality decreases to an unacceptable level. it will not shut down, and you will not see a "change drum message." if your paper feed problem is centered around the cassette/paper pickup area, you can try cleaning your rollers with water and a soft rag, and also make sure your rear paper stopper in cassette isn't pressing too tightly against the rear of paper stack. best to leave 1/8" gap, otherwise paper will not lift properly to the rollers.

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.
