Streaking, smudging, black lines, and double images are all symptoms of a bad fuser. When you notice these printing defects and experience problems, such as paper jams or wrinkles, this is a good sign to replace the fuser kit.
Paper jams can occur for a variety of reasons, such as overloading the paper tray, loading different thicknesses of paper in the tray, or using paper that isn`t appropriate for your particular printer.
The following are the top reasons why paper jams occur:
unsupported paper/media is used. incorrect paper settings in the tray and/or the print driver. paper loaded incorrectly and/or paper edge guides not adjusted properly in the tray. humidity and/or paper condition and storage.
Loading paper that is stuck together, frayed, curled or bent can cause a jam. Overloading the paper tray, loading different thicknesses of paper in the tray or using paper that isn`t appropriate for your particular printer can all result in a jammed printer.
Dust, paper fiber, and other debris might accumulate on the paper feed rollers and cause paper jams and paper feed issues. Clean the rollers inside the printer, and then try to print again. Turn off the printer, and then disconnect the power cord.
Low-quality paper leaves an accumulation of tiny paper bits often referred to as “paper dust” inside the machine. This “dust” is one of the top causes of paper jams. More dust means more jams. Besides jams, the dust also contributes to poor-quality prints and causes machine parts to wear at a faster rate.
Moisture in the paper will cause the printer to jam. You are using recycled or low-quality paper with excessive paper dust. The dust from the paper can build up on the rollers and cause a paper jam. You are using paper with bent corners or printed on before.
If you have not installed a drum unit or have installed the drum unit improperly, then this may cause a paper jam in your Brother machine. If the error message remains, open and close the front cover and fuser cover firmly to reset the machine.
The jam is caused by excess toner that is on the page sticking to the fuser roller and not releasing as it should. The way to avoid this is to reduce the surface area on the fuser roller and we do this by turning the paper around to A4-R in your trays.
Common causes of paper jams include: Damaged rollers. Inserting paper that is incompatible with the printer. Loading the paper incorrectly.
Paper jams can occur for a variety of reasons, such as overloading the paper tray, loading different thicknesses of paper in the tray, or using paper that isn`t appropriate for your particular printer. False paper jams can also occur.

HP Laserjet 6MP wont feed paper
ANSWER : I had a similar paper pickup problem on laserjet 6mp. The printer would go through start-up sequence fine but when it received a print job you could here the main gears/rollers turning but no clicking from paper pickup solenoid, then eventually error lights would come one . I incorrectly assumed it was an error with the paper pickup mechanism and wasted a whole day taking the printer apart and replacing the paper pick mechanism. Long story short, if I had bothered to figure out the secondary error light codes from the start, I would have realized it was just a bad fuser and would not have wasted so much time.

Paper Jam and carriage jam code when nothing is jammed
ANSWER : Did you try cleaning the encoder strip that runs through the cartridge assy.? Use Window Cleaner on a paper towel. Also, check inside on the right. I’ve seen a lot of times where there is a folded up scrap of paper that stops the carriage from going all the way to the right.
