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 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.
The message `Fuser Error` or `Self-Diagnostic` means either the fuser has reached the maximum temperature allowed or there has been an error in detection of the correct temperature during specific times of the printing process.
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.
Close the fuser cover by pushing on both the left and right hand side. You will hear a click when the cover is closed securely.
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.
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.
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 melts the toner particles, binding them to the page. The speed at which the paper passes through the fuser is what keeps the paper itself from burning. If the speed were slower, the paper would combust and burn.
