SOURCE: How do you clean the drum?
Brother had me take a tissue and wipe the drum. You can spin it with the gear on the left had side of the drum. Then they had me slide the blue tab 30 times back and forth.
Also take a soft cloth and clean the lens on the inside of the printer. First take out the drum unit. The lens in toward the back.

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.

I found the answer in another group, from Sunshine3240:
Open the front cover and leave open while completing the following steps:
Turn the printer off.
Hold the 'go' button while turning the printer on. All panel lights should be on.
Release the 'go' button.
Press the 'go' button 2 times.
Press the 'go' button 5 times.
The toner light should be off.
The paper light should be on.
Close cover. The ready light should be the only light on.

currently, the error you have is not a service errorl, ready and alarm blink means that you have either a paper jam, no paper, or a paper misfeed.
do you get this error only when you try to print?
according to the service manual the lights can not alternate in blinking.
