The problem is a down cracked gear on the fuser drum itself. To remove thefuser - remove the tray at the bottom and the back tray (4 screws, 2either side) lift out the phone line box on the right (looking from theback - 2 screws) and swing it out of the way (careful as cable isn'ttoo long) 2 screws either side of the fuser (long black object at thebottom) unplug the halogen lamp (white plug on left) and small 5 wireplug on right, and lift out fuser unit. Nasty brown cracked gear is onthe side where the small 5 wire plug goes. (LJ7416001 - HR GEAR 34 Ithink the part is)

You can get the part from the below link

Good luck.

Brother MFC-8840D printer w/false paper jam indication.

With my Brother 8840D I have had paper jams that when cleared would not delete from the display nor would the machine operate until I unplugged the machine for around eight hours. I guess it is a sort of reset or reboot.

My document won't print. Printer says Check Paper

It most likely means you have a paper jam. Check to see all the trays where the paper would pass through. In and outwards.... you will find your piece of paper.... it can also be very small too so pay close attention. Remove it and try sending the document to be printed again.
