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.

Apparently my computer was stopped in the process of printing a document of several pages. When stopped the paper was mid-way. Can barely see part of sheet from front and nothing in back. Cannot move it by pulling on it. Do not want to tear it off completely. Can't locate my manual.
