Question about Brother MFC-7340 All-In-One Laser Printer
Certain Brother models have this problem. It is a loose screw on the fuser cover assembly. Instructions for tightening this screw are here. You don't need to grease anything - in fact it tells you not to lubricate this gear. Easy fix, took me 10 minutes!

Commonly caused by High voltage discharge or arcing from a dirty primary charger corona and grid.
You need to clean your drum unit.
Open the front door and pull out the Drum unit.
Look on top of it for a small (usually) blue slider, sitting in a 10mm slot that runs the length of the Drum unit. This is the corona cleaner.
Slide this back and forth about 6 times, ensuring you return it to the original starting position.
Reinstall the Drum unit and try printing.....

You open the front door and pull out the drum and toner assembly and then press the blue lever to release the toner from the drum, place the new toner in the holder and install both together into the machine.

Open the front cover.
Press the clear/back button.
It'll ask if you want to replace the drum, but ignore that and just press *11 quickly. It should say "Accepted" on the LCD. Close the cover and it should work.
