The fuser unit or fuser assembly, is a critical component of your laser printer. Using pressure and heat, it fuses the toner powder onto the page to create a print, and without out it, your printer cannot operate.
The HP LaserJet Fuser helps make sure your HP toner is applied to your paper evenly and with vivid color and detail on every page without putting a major dent in your budget. It lets you print up to 150,000 pages of dynamic quality before you need to replace it.
A component found in electrostatic printers, laser printers, and xerographic printers and photocopiers. The fuser unit is used to permanently bond toner to a substrate by applying heat and pressure. A fuser unit is made up of two rollers; one to apply heat and one to apply pressure.
The fuser is located inside the printer just behind the four image drum units. Warning! If the printer has recently been powered on, some fuser components will be very hot. Handle the fuser with extreme care, holding it only by its handle, which will only be mildly warm to the touch.
Fuser Units

The coating wears off and causes the toner to not fuse properly. There are replacement rollers and sleeves on the market that you can replace and turn a non-functional fuser into a good working one. Rebuilding fuser assemblies is not a new thing.

The fuser assembly has two blue handles (red arrows in picture below); hold those two handles as you pull the fuser straight out and remove it from the printer. Install the new fuser in the same manner; make sure it is seated well, and then close the door. That`s it for the fuser!
The fuser unit is a periodic maintenance part and should be replaced to maintain optimum print quality and reliability and to prevent paper jams.
The fuser unit or fuser is a critical part of any laser printer. Using pressure and heat, it fuses the toner powder onto the page to create a print, and without it, the printer cannot operate.

The fuser unit or fuser is a critical part of any laser printer. Using pressure and heat, it fuses the toner powder onto the page to create a print, and without it, the printer cannot operate.
Removing and re-installing or replacing the Fuser while the machine is powered on may cause damage to the machine and cause it to become inoperable. WARNING: The Fuser and surrounding area may become very hot during operation.

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.
