    Exact same problem. I think it began after installing recent (July 2008) Firmware Upgrade.

    Same problem, but after purchasing reman brother toner cartridge. I refilled the original cartridge myself and after it emptied I purchased this remanned one. Printed great in beginning for about 2 days, then error starts repeatedly. I did read the user manual for this error and it gives suggestions to delicately clean the drum with swabs, etc. The apparently has some electrostatic material that is ver delicate. If anyone has a suggestion to bypass this error since the drum doesn't even rotate before the error occurs, I'd greatly appreciate it. $59-70 is too much to print and I really don't believe I got much printing out of the original cartridge at round 1 when it was new.

    Same problem starting in April 2008, after running for 6 months and using about 3 cartridges during that time with no problems. My wife declared the MFC-7820N laser printer useless after encountering the drum error message constantly with a newly installed "brand new" remanufactured cartridge. She swapped the laser printer with my old inkjet MFC.



    I believe the problem is really related to the motor that drives the cartridge mechanics. I suspect that the electronics is sensing that too much motor current is required to drive the cartridge (which could be a drum problem) and generating the drum error message.



    I have taken problem cartridges and sprayed a little lubricant here and there on gears and then manually used a large screwdriver in the drive connection to rotate the cartridge mechanics to work the lubricant in and reduce the torque required to make the cartridge work.



    After that treatment, I got a lot fewer drum error messages. Just don't get anything on the drum itself or rollers, or the cartridge is toast.



    I seem to remember reading somewhere that Brother has used the TN-350 cartridge for years in a lot of different machnes. The older machines had more gear reduction to drive the cartridge (developed more torque), although they were slower. A remanufactured/refilled older cartridge may expect more torque to drive it than the faster MFC-7820N is capable of developing reliably.



    You may have to buy new Brother TN-350 cartridges to get the reliability you want out of the MFC-7820N.



    I noticed that others had some success refilling the original cartridge from Brother. If new TN-350 cartridges from Brother require less torque, they would work in all the old machines that use TN-350 cartridges as well as the newer MFC-7820N.

    I finally found the root cause of my "drum error, slide the blue tab back and forth" message.



    I replaced the after market drum unit that came as part of a "toner cartridge" with a new Brother DR-350 drum unit (bought from Amazon).



    I finally figured out that Brother toner units are made up of a drum unit and a toner cartridge. When buying a non-Brother toner cartridge, for whatever reason it is quite common for the cartridge to be sent in a drum unit (which you and I have found out is worthless junk - hence the error message). For those of us with other laser printers where the cartridge includes the drum, it seems reasonable to pull the whole toner unit out of the Brother printer and replace it with the non-OEM unit we just bought. However by doing that, you just threw away a good drum unit and replaced it with a bad drum unit.



    I have no clue as to why the aftermarket sells toner cartridges with bad drum units included. I have even seen stickers that secure the two together with a "Do Not Remove" message. Trust me, break the sticker and remove the after market cartridge from the included drum unit and install the cartridge into your original drum unit. I have found that even if the after market drum unit looks good, it will still give problems.



    Make sure if you replace the drum unit to reset the page counter. On the 7820N printer you 1) open the front cover, 2) push the OPTIONS button, and 3) select Y for replace drum. Otherwise you'll get the replace drum message sooner than you should.



    I hope this helps others.

    I have a Brother MFC 7220 that constantly says "Drum Error" too. No amount of cleaning the corona wire will get rid of it. It is an after market toner cartridge, but I am not sure about the after market drum (I cannot recall - bought them at Rapid Refill). The aftermarket cartridge and the drum both say "Brother". Do you think this is my problem?

    For MFC-7340, same as above, but use the Clear/Back button instead of Options.

  1. Open the front cover.
  2. Press the Options key on the control panel.
    The display will show "REPLACE DRUM - 1.YES 2.NO".
  3. Press 1 to reset the drum count.
  4. Close the front cover.
It happens because Brother decide that we are morons and cannot figure out when a drum is dead and so they make the printer refuse to work after a certain amount of time. This resets their dummy counter.

"Drum error" is because there is dust or any thing like ink on the drum.
After I filled the toner with a other brand dry ink, I got this message.
I carefully checked the drum, I found there was some ink on the drum. So took off the toner part, washed the drum kit with the tap water. wait it dry. There is a rubber roller inside, it will take time to dry.
after the drum kit dry, I rolled the drum, there still something on the drum, I use a tissue paper cleared it.
put the toner back, insert it back to the printer. It is fixed.

I just installed the July 2008 Firmware upgrade and started getting this message.
Never got it before. I have a Brother toner cartridge and drum. No amount of cleaning will get the error to go away. I'm now trying to figure out how to install the old firmware.

  • ff_mac Nov 23, 2008

    The Brother firmware installer is an online app that automatically chooses the latest firmware. Looks like I am running version 2.4. Problem never occured before I upgraded to this firmware a couple of days ago. Anyone know how to downgrade the firmware?

My MX922 printer worked well this morning. All cartridges have ink but ALL lights under the cartridges are on and print comes out blank. There are no error codes or anything abnormal displayed


This problem is mainly happens to all inkjet printers. If your printer print blank pages then please at least once go to official site of Canon and check whether there is any printer/scanner drivers update is available or not. If yes then download it. Also check your ink cartridges. Because if there is no print on paper that means your ink might be dry.Sometimes it clog the print head. If your ink cartridges get dry change it. Or you should clean your printer's print nozzle by using printer's control panel. I hope all these suggestions helps you. If doesn't then watch Canon MX922 Manual English

My Epson WF-3640 is printing with gaps in the text. How do I fix this issue?


Make sure you should remove shipping tape from the ink cartridge. These taps are used to protect printer during shipping but you have to remove it before starting printing. Beacuse these taps prevent the ink to entering in print head. If you will not found shipping tape in your printer then there is terr off strip, remove it. The tear off strip seals the the vent holes on the top of the cartridge to prevent it from drying out on the shelf or during shipping.
After ensuring that the shipping tape has been removed, run the printer's "Head Cleaning" utility to prime the cartridge, then print a test page.

Laser printer makes light clicking noise when idle


When idle is potentially the fuser unit, after heating and cooling. However the print quality issue associated with the clicking sound could indicate an electrical issue. The HVPS maybe faulty causing the print quality issue (due to dependant parts) and the electrical click. In any case I would recommend calling Brother and finding the nearest authorised service agent.

LSU error SAMSUNG SCX 4725FN


Laser Scanner Unit or LSU is what writes to the surface of the drum. The glass above the cartridge in the machine may be dirty. The mirror motor in the LSU could be bad or needs to be cleaned to spin better. The Laser diode may be faulty.

This is not a user-serviceable issue. You will need to contact Samsung for a service. You can do it online via Samsung website or contact the vendor to see who will they appoint to service the printer to, especially if it is still under warranty.

Printer won't recognize cartridge


I had the same problem. I'm not sure but I think I replaced the cartridges when the printer was on because I turned the printer off and removed one of the cartridges. When I turned the printer back on it recognized that cartridge but not the others. I turned the printer off again, rmoved all cartiridges and put them back in when the printer was still off. When I turned the printer on again I had no problems. So...try turning off the printer, rmove all cartridges, then put them back in and restart printer. Hope this works for you .
