Question about Brother MFC 9970CDW - Multifunction fax / copier / - MFC-9970CDW

Open Question

How do I fix drum error? Have cleaned the corona wires numerous times, but the machine won't stop giving the message.

Machine was operating well until recently. I have changed cartridges, reset everything that seems resettable, and cleaned corona wires repeatedly following instructions. Used to start up and do a few pages, now it won't start up. Just goes straight to the drum error message.

SOURCE: double print or a shadow print

You have probably been using non genuine toner, some kinds of this toner is not the same quality as Brother toner and just chews you drum out before its due to be changed. Change the drum and use genuine toner.

SOURCE: cleaning message

the drum unit may have a full waste toner hopper, I am not sure but defintely do not clean, or touch the drum, you may touch the the drum unit which has a corona wire which occasionally may need cleaning by running a wand across it. there should be a colored clip that will slide back and forth on the drum catridge to clean it.sorry i couldn't be more helpful without actually seeing it.


Thank You,

Mikey

I have this manual for you. I can be reached at LBrown18062@hotmail.com

Drum Error - The corona wire on the drum unit needs to be cleaned.
Clean the corona wire on the drum unit. (See Cleaning the corona wire on page 122.)

Cleaning the corona wire: If you have print quality problems, clean the
corona wire as follows:
a. Turn off the machine's power switch.
Unplug the telephone line cord first, disconnect all cables, and then unplug
the power cord from the AC power outlet.
b. Open the front cover.
c. Slowly take out the drum unit and toner cartridge assembly.
CAUTION: We recommend that you place the drum unit and toner cartridge assembly on a clean, flat surface with a sheet of disposable paper or cloth underneath it in case you accidentally spill or scatter toner.
Handle the toner cartridge carefully. If toner scatters on your hands or clothes, wipe or wash it off with cold water at once.
To prevent damage to the machine caused by static electricity, DO NOT touch the electrodes shown in the illustration.
d. Clean the corona wire inside the drum unit by gently sliding the green tab from right to left and left to right several times.
CAUTION: Be sure to return the green tab to the home position (a) (1). If you do not, printed pages may have a vertical stripe.
e. Put the drum unit and toner cartridge assembly back in the machine.
f. Close the front cover.
g. Plug the machine's power cord back into the AC power outlet first, and then reconnect all cables and telephone line cord. Turn on the machine's power switch.

The fax machine is saying remove the drum there is dust on the corona wire.


Use the corona cleaning wire to clean the dust off. Open the front cover. Remove the drum/toner unit. look on the right side of the drum portion above the toner unit for a plastic tab with a triangle arrow that points to the left. Slide this tab back and forth several times. Move the tab back to the right. Reinstall the drum/toner unit. Close the front cover.

Clean the corona wire in this manner every time you change the toner/drum.

My brother MFC9840cdw has an error message that says, "drum error, slide the green tab on each of the colored drum units. Refer to the users guide". I have tried sliding the green sliders several times. I...


The guy that replied solved the problem. He rocks and I can't believe that brother does have a large posting on this issue. Sham on them:
ben2913 did the job "This is NOT the solution to this error code. The code is telling you that the Corona wire must be cleaned. Remove all 4 color drums. Look down into the tray that you removed them from and you will see 4 green tabs. Open the plastic cover that protects the corona wire and move the green tab back and forth several times. After you have done this with all 4, reinstall the drums, close the machine front and everything will work fine again."

Fax machine has a message that says "open front cover to remove the drum. Clean the corona wire located on the drum."


The fax machine instruction must be done to erase the
message. The corona wire located on the drum needs to be cleaned.

Corona wire needs adjusting


Of you need to remove the toner cartage the if you look on the roller side of it you will see a tiny yellow tab on the right side I believe that is the corona wire cleaning tab. You press down or hold on to it and slide it back and forth left to right thus cleaning the corona wire.
Also the message corona wire needs cleaning often is displayed close to the end of the toner life so after cleaning and reseating the toner back in the printer wait for it to self test 10 sec or so and the press three times the blue large (only) button on the printer. You need to press it at a good speed for the printer to respond. Press to fast it won't work.
This will give you a printer setting page on it the toner life will be displayed along with estimated drum life and good deal of other information.

Alarm is flashing, LED reads install Cartridge but the cartridge is installed. Any suggestions? Yes it is the right cartridge and I have tried replacing it with a new one, same error message


You've most likely got a dirty corona wire and/or drum. The wire should be cleaned each time you change the toner as well as if/when the print quality starts to degrage. Remove the toner cartridge, give the corona wire several swipes with the tab and make sure the tab is put back securely in place. If cleaning the wire doesn't fix your problem, go ahead and clean the drum. Either one of these or both should solve your issue. Only other thing that could cause your error would be the toner cartridge is not securely in place. (shouild click in securely). Best of luck.

CORONA WIRE CLEANING


SWARNAVA has the most common wrong answer to this problem...

I am waiting for a firmware update to fix this issue. The only solution is repeatedly removing the drum/toner, moving the green cleaner back and forth, putting it all back together loosely, putting it in the printer loosely, and closing the door gently. Hold down the blue button until all the lights glow, then release. If you're lucky you only have to repeat this process a dozen times until you trick the sensor into not giving false readings.

Drum error


Yes, you should replace the drum unit if you have not done so. You may have a broken corona wire or drum. However, keep in mind that you will need to reset your machine after changing the drum unit. If after replacing, you still get the same error, you may have a problem with your machine properly sensing your drum unit.

Dust on Drum...


I had this problem too. I took out the drum and vacuum the drum with a vacuum cleaner ( no brush ) while at the same time manually rotate the drum cyclinder. It worked. After a month or two, you might have to do it again. But everytime, it solved the dust problem.
