Paper jam 1540 Brother printer - Brother Office Equipment & Supplies

Try shutting the printer completely down & unplug power. then plug power back in and while holding down all buttons on the printer control panel, turn it back on. this should put it into a self diagnostic mode that prints out just about everything the printer can do, including a sample page. Also, be sure all rollers are clean & trays are completely closed before restarting. If the printer works when you do this, you should most liely check all settings in the software package (driver) or perhaps reinstall the drivers. If this is necessary, be sure to download the latest drivers from the Brother website.

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.

Actually, you need to double check the back cover and front cover, open them all to check all paper jam.
Besure to check the back cover, normally all paper jam is from the back.
be sure to close the front cover at the last cover to close.

Usually small pieces of paper are jammed at the print head area. Lift up the scanner and see if you can find the paper at the print head parking area, clear the paper . If you can't find the paper, remove the scanner cables, then the scanner. You will see 2 screws at the rear and one near the USB connection. Another 3 screws towards the front will remove the front panel. Under the panel remove 4 screws and the two panel harnesses. The is a speaker harness which you must remember to attach back later (most people don't remember to put back). Lift up the top cover and you can see the whole engine. Clear any pieces of paper that might be there.
