Ok, we had a paper jam. But after clearing all the pages out without tearing any of them, the Rear Cover Open error message continues to show. I've followed the procedure for clearing a jam from the Brother website, but the error message still shows.
Does anyone know how to clear this, override it, or fix the broken microswitch that is reporting an open cover?
Much thanks in advance.

Re: Rear Cover message stuck on
First, try shutting off, and unplugging the printer to do a reset on the micro & logic circuitry.
If you actually have broken switch or lever which actuates the switch, then an obvious solution is to replace said broken part. Or, if indeed a switch, you could possible bypass & defeat the switch so it doesn't sense the door open.
If this is an actual mechanical switch bypass is fairly simple. You will need to find out if the non-fault (normal operation) condition is either an Open or closed switch and either short across the switch contacts (closed) or pull a wire off (open).
If desperate to get the printer running, bypass the switch, use the printer, and get a replacement part ordered in the meantime, then install the new part to restore proper operation.

Clearing Paper Jams If the printer's control panel displays a paper jam message, look for paper in the locations indicated in Figure 22, then see the procedure for clearing the paper jam. You might need to look for paper in other locations than indicated in the paper jam message. If the location of the paper jam is not obvious, look first in the top cover area.When clearing paper jams, be very careful not to tear the paper. If a small piece of paper is left in the printer, it could cause additional jams. If paper jams are a recurring problem, see page 78.(A paper jam message might also display if the rear door is open.)
The top cover of the printer must be opened and then closed to clear a paper jam message.Paper jams can occur at the following locations:Output areas(top and rear)Go to page 75.
Loose toner might remain in the printer after a paper jam, but thetoner should clear after a few sheets are printed.
The sensor may be dirty even if it looks like there is no paper jam. Take a bottle of compressed air and give it a once over. Make sure you don't shake or tip the compressed air as you don't want to fast freeze anything.
If this does nothing, you probably have a failed sensor which will need replacing.
Remove any paper trays. Inspect them for wrinkled or damaged paper.
Also open the back cover of the printer if this model has one.
Open any other doors that give access to the printer's paper path and to the toner or ink cartridge.
If necessary, remove the toner or ink cartridge. Place it away from light/ sun light to avoid damaging it.
If you find a piece of jammed paper, remove it by
holding it with both hands and pulling firmly. The goal is to keep the
paper from tearing. If several pieces are jammed together, try pulling
out the middle piece first to loosen the jam.
If the paper does tear, try rotating the roller gears manually to free the paper. Don't force anything, though. Do
this step especially if the jam message comes up repeatedly without any
obvious paper jam, there may be a small tear of paper inside.
Ones the printer is free of paper Replace the toner or
ink cartridge and paper trays, close any doors you opened and turn the
printer back on.
If the printer paper jam message still appears, then there is still some paper in the printer. Reinspect the paper path.
see alternative if the problem is still not solved.
a piece of thick paper, for example photo paper and press the resume
button (may be diffrent button on diffrent models) a few times to the
printer picks up the paper and puts it through the machine.
