Brother mfc 8440 error 78

This refers to a error with the fuser temperature you need it repaired by a service technician. Parts can be as little as $15 for the thermistor sensor or as much as $100 for a new fuser.

Why does my MFC 9420 keep getting a paper jam in the back (at the fusing roller)?

Perhaps the fuser drive gear is broken or there is some object stuck in there. When it's printing, check to see if the fuser rollers are turning. Drive gears do occasionally break.

Brother MFC 8440 makes very loud noise when printing/copying

Very commonly a broken gear on the right side of the fuser. Replace the fuser and this will fix your issue. Let me know if you need a part number and pricing.

Good luck!

Replacing Brother MFC-8440 Fuser

To remove the fuser - remove the tray at the bottom and the back tray (4 screws, 2 either side) lift out the phone line box on the right (looking from the back - 2 screws) and swing it out of the way (careful as cable isn't too long) 2 screws either side of the fuser (long black object at the bottom) unplug the halogen lamp (white plug on left) and small 5 wire plug on right, and lift out fuser unit.

Not a easy gear to get to, entire side frame must be removed. I always just replace the whole left frame as pictured, but really you only need to replace gear pic at top, like I say not easy, take pics so you know how to reassemble it.
