Question about Brother MFC-7820N Laser Printer

Constant Paper Jam

I have a brother 7820N laser printer/fax/copier. I have had it for about 15 months or so.

About a month ago, it started jamming every time I print. The paper will crumble up internally, and I have to open the back and really yank on the paper to get the jam out.

Any ideas on how I can fix that?

    It' been jamming paper everyday for the past few months. However, it is a 2 year old machine and I guess we've used it a lot for faxing, scanning, copying! I thought it was the summer heat but today it was cool and it still jammed first thing in the morning. I might try to replace the drum early and dust the fan.

    I've got the same problem. I noticed that mine works for a little while if I spray that canned air on the back at the top where the paper feeds through at the very end of the print run. I also noticed that the roller bar I was spraying rolls loosely now; before it was tight and I could not turn it.

    My symptoms are that the paper prints just fine, except it won't feed through the very last set of rollers, and so gets forcefully jammed by the rollers below.

    I experienced the same jamming on a relatvely new printer- 1 year. My previous brother MFC was much more durable- over the course of 7 years I do not recall frequent jams.

    I have ours for 3 years, and it is now jamming on every page. It prints fine, but the last set of rollers are not doing their job. Paper is grumbled. We are using 20lb paper, and will try a heavier paper.

    I bought a MFC 7820 about a year and half ago, though I used it occasionally till this year I used a lot for printing exam notes. It happens often that the message showing paper jammed. It's not difficult to fix, only needs to open front cover and pull out the paper. The paper was rolled half way from the tray. But still it's really annoying as the print is interrupted all the times. Consider it's almost new machine, I fee the quality is not very reliable.
    The print result is not good as those commercial one, it's ok for home use.

    This was great for three years, now it's jamming on every print job. It's jamming at the document feeder tray, like the rollers that accept the paper aren't pushing it all the way out. Very annoying, tried and tried to fix it, going to have to get a new machine.

    Had mine about a year and a half, now jams every time.

    We have the same problem, but it happens sporadically. Very irritating. Tried cleaner the rollers I could get to without taking it apart. Plus used compressed air throughout the printer. Still making my prints out all look like an accordion.

    this printer is ****. It just started jamming up. Tried different paper without any luck. Call the Brother help line. All they had me do is the steps in the book, then when that did not work they said I should have it serviced. I think I will end up getting it serviced by the dumpster.

    Just gonna get a new one since repair would not be much different than that of a new printer. My problem is excatly as we all here have described.

  • artbros Mar 04, 2009

    Printer often fails to pick up paper from the tray. It is getting progressively worse but could be solved by opening the tray, pulling back the half-pulled sheet of paper, setting it back into the tray, closing the tray and then briefly opening the front cover to trick the machine into thinking the jam has been removed. The machine would typically pull the sheet and print.



    Irritating, but not that big a deal.



    Now the machine is not only doing the failure to pick up described above, it is also raveling paper as it moves through the lower and upper rollers. When caught in the upper rollers, the paper gets the "accordian" look described in other posts. The paper is fully printed, just ugly and unsuitable for anything where appearance matters. And the machine will NOT reprint the page automatically on an upper roller jam unless manually re-printed from the computer.



    When caught in the lower rollers the page is more difficult to clear, but I've always been able to gently pull it out through the front. The page is only partially printed with this type of jam. The machine seems to know to reprint the page after it is removed from its innards.



    I've called Brother support and found them to be useful. But in this case they referred me to an outside service shop. Given the cost of typical service, it seems like replacing the unit is the best answer. It would be good if Brother gave an idea of what it costs to have new rollers put in - but they do not.



    I bought this, in part, because it seemed to have most of the important parts replaced when I put in a new drum cartridge. Alas and alack.



    I've liked this machine for the three or four years that I've had it. It was replaced once - under the long-term 3-year warranty I bought with it. Probably two years into the deal. Then this failure roughly two years in suggests that two or three years is the max you can expect prior to catastophic failure.

    I am having the same problem with the paper jam. I purchased 2/23/06 and it has been a great multi unit with excellent BW copies and printing. We are an insurance and real estate agency and printer has had lots of use and has been performing well until last couple months when the paper jams began. No lasting remedy so far. After pulling out jammed paper, I pull out the drum and stick it back in, and it seems to run ok for a few copies before another jam or it will sound like a jam and will despense accordian paper. I sent email to brother today asking for remedy.

  • Arijase Apr 13, 2009

    I will never, ever buy a Brother printer again. After less than a year, the stupid thing started jamming after only partially pulling a piece of paper through. At first, I just made sure to keep the right amount of paper in it (it seemed like if the paper was about halfway down, even though there was paper in it, it would jam right away.) Now, it won't stop jamming no matter how much or how little paper I put in it. We have a small business and rely on it for printing, faxes, etc. What a joke! They charge over $100 just to look at it, not to mention parts needed to repair, so are we supposed to just use these as disposable products and expect to throw these pieces of **** out after a year and buy a new one? I'm disgusted!

I have the accordion paper jam problem as well, almost all the printout got jammed. So I opened the back panel and unscrew 2 screws and take out the part with the small plastic roller and clean those. Then I also see a rubber roller on the ceiling of that area and cleaned and rubbed them with a damp cloth and rolled them several times. Now it's been 2 weeks of jam free printing! Back to being happy customer...

The spring is held in place by the right hand screw just above the fuser. You can see a small plastic nub (molded) that holds the spring in place while the screw locks it in.

Have you tried shutting it down completely? Also, double check to see if the inside of the printer is completely clean.

There is a little cover there that has a sensor flag on it. It is most likely in a jammed position. If you are able to carefully take the cover out, you can bend it slightly, readjust the sensor flag, and reinstall it.

How do you remoce the drum to clear a paper jam on


Lift the top, remove the toner and open the access panel in the back, remove the printer tray. You should be able to see the full path the printer takes from start to finish. Rarely do you need to take anything else apart. If these areas are clear as the printer will attempt to clear jams when you start it up.

I get a load paper message when paper is loaded


Probaply some paper or obstackles stuck at PE (paper empty sensor) and that could be hard to fix it cuz you may need to pull apart the printer. However, if it is 6 monthsold, warranty covers this problem.
