A fuser unit is made up of two rollers; one to apply heat and one to apply pressure. The heat roller is a hollow (usually metal) tube that is heated by a radiant heat lamp suspended in its centre (so the tube is heated uniformly), while the pressure roller is a backing roller made of rubber.
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.
A fuser unit is a pair of heated rollers within the printer that fuses the toner onto the paper being printed on. Toner particles are pulled to the paper to create the desired text and images as the paper passes the imaging drum.
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.
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 unit is a heated roller that melts the toner particles onto the page as it passes through. This seals the toner to the page so it`s no longer in powder form and makes sure that the toner doesn`t smudge of fall off the paper when it comes out of the printer.
The Original HP Maintenance Cartridge is designed to make your HP Designjet printer even easier to use by enhancing system reliability. You get trouble-free printing—every time—and fewer interruptions to help you get the job done right and on time.
A maintenance kit should include a new fuser assembly, and a fuser kit should include all the necessary maintenance parts. The fuser assembly refers to the part of the printer that uses pressure and heat to fuse the toner into the material you`re printing on.
