HP LaserJet 4100 Fuser RG5-5063.
The fuser unit is a vital component of laser printers. Most fusers last between 50,000 and 200,000 pages, depending on the design.
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 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.
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 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.
The message “Fuser Kit Low” or “Fuser Kit Very Low” on your HP Color LaserJet M553 series printer is a warning that you have reached the recommended number of prints for your fuser assembly. (The fuser assembly is the consumable part in your printer which heats up and bonds toner to the paper.
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 is a part of laser printers that bonds the toner and paper together using heat and pressure. Fusers need to be replaced every 75,000 – 300,000 pages depending on the printer model.
Working out how much you use your current printer is a good way to determine the benefit of repairing it. Printers have a lifetime volume limit. If you are still a long way from hitting that limit then printer repair makes good sense. But if you are nearing the limit, the cost of repairing it might not be worth it.
The most common location to find your product information is on its label. For most HP products the product label is on its bottom, its side, its top, or its back. On some products, it might be inside a battery compartment or behind an access panel.
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!
