5A means that the purge cam stopps abnormally when it is in use. This could be of a broken cam shaft. You have to replace the whole purge unit. This is a service job to do!

The encoder strip switched off the ph and has to be set into place again.
see here how to fix it:
(enlarge the browser window to see pics somewhat better)
when you have set the encoder strip in pos. again stick some scotch tape on the top of the ph cover where the strip runs thru to prevend the slipping off again on next paper jam ;-)

I had the same problem with a Brother MFC-8460 and called Brother's support line. The solution that worked for me was to lift the top cover where the sheets of paper go through when you fax. On the right of the black rectangluar piece with grey roller there is a slot in the tray with a black lever inside. The black piece was stuck down inside the slot and had to be popped back out. Once it was out I hit the stop button and it was fixed!!

Turn the machine off and hold menu while turning it on and keep holding it while the machine starts up. This should go into maint mode.
When it gets into maint mode you can try 99 to exit. This is like a soft reset. Hard reset is hitting 01 in maint mode and then 99 to exit.
Let me know if this is helpful.

Brother Scanner error message.
After much time with Brother Tech support. The solution finally turned out to be as simple as downloading this file to reset the drivers.

Pros: This is a pretty decent product as far as ink jets go.
Nice to be able to use the feeder to scan multi-page documents and even cover two sides by running two passes and then the software interleaves the pages to make a seamless pdf file.
Cons: Ink jet technology. It worked very nicely for a year and then a few jets plugged up and wouldn't clear out even with cleaning.
Today the unit is dead, reporting error code 5700 and refusing to do anything after a paper jam.
Cartridges with chips.
I was pretty happy with this printer until one day it decided to grab
about 30 sheets of paper at one time from the top feeder. This created
a pretty major jam, and it reported the error code 5700. This jam must
have stripped something in the gearing since now all it will do is
report this error even after power cycling. Web search reveals that
this is a serious fault that requires it to be sent in for repair. Yea,
right. This unit is designed to be never disassembled since everything
snaps together and opening it up is a major puzzle.
This is only reader review which i found in the web. this may tell you what is the error is all about..
