Normally clearing the drum count the machine has to be on open front cover as if to change the drum press and hold the button in for about 10 second then release and shut the door. This should reset the count if not please get back to me and I'll check the service manual to see if anything in that.

Thanks J

SOURCE: Paper jam with Brother HL-2030 laser printer

Being a retired electronics technician, I located and downloaded a copy of the service manual. Then proceeded to hunt for the reason why the Paper LED was staying on. I put the printer into the Production diagnoses mode, then by process of alimination opened and closed each panel and cheack each sensor switch one at a time. At which time it was apparent the problem was the rear door sensor. So I started to disassemble the printer getting instructions from the Service manaul, as most electronic equipement there is a sequence process to accompliah this. and once I found that the method of the rear door sensor operated I found the bracket was not in the right position. I put the sensor bar back into it's proper position and put the printer back to normal opperateing mode, I found my problem was solved. So I reassembled the unit and plugged it back into the compter ran a couple of test sheets and cleaned and aligned the printer head(s) made a few adjustment and everything was back to normal.
I must say that locating the Service Manual was a feat, but worth every cent I paid for it which was $9 USD. Personally i think all service manuals should be available for all Brother products for a fee, then a large number of problems can be fixed by the owners without much bother to Brother.
I ahve two of these printers and would still purchase a Brother colour printers, my next purchase is going to be a Brother color laser printer. Out of all the printers i've used on my computers I like the brother the best.

thin sensor (looks like steel colour ) is not in the proper position.it is in the back side of the printer to the lower side where you feed the paper. irepair this problems regularly for my customers. you can do it your self it is very easy.just make your sensor move up and down properly it should not be blocked somewhere.rate this solution as fixya to encourage us to solve more and more problems like yours.good luck.

OK figured out the sequence to resolve this error:

power off unit
unplug power cable for 1 minute
reset the power cable
open front door
press and hold the reset button under the lights
turn the power on
printer should then be reset
