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 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.
This error might display if the fuser temperature becomes too hot. Follow these steps to turn off the printer and allow the fuser to cool before printing again. Press the Power button to turn off the printer. Disconnect the power cord from the rear of the printer.
50 error is a fuser error and means the fuser needs to be replaced. Do a search for the part on google and then see if it is worth repairing based on cost of the fuser and if you will need to hire someone to replace it for you.
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 biggest difference lies in the name, as they tend to include all of the same parts. A maintenance kit should include a new fuser assembly, and a fuser kit should include all the necessary maintenance parts.
Parts that may be included in a maintenance kit are the fuser assembly, transfer roller, pickup rollers, separation pads, corona assembly, fan assembly, cleaning cloths and gloves. The fuser assembly is a pair of rollers that fuse the toner into the fibers of the paper.
The imaging cartridge is separate. You have the toner cartridge, and the imaging. The Maintenance Kit is a separate kit that contains a number of items to be replaced in the printer.
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 50.1 fuser error message refers to a low temperature reading on your fuser. If you see the error message “50.1 Fuser Error” on your HP Color LaserJet 2820 or 2840 series printer, you probably need to replace the fuser. Fusers are a consumable part and are sold as part of a maintenance kit.
50.2 error indicates that the printer is not heating up fast enough. This can be caused by a bad heating element in the fuser but can also be caused when the printer does not have adequate power due to overloaded circuits or being plugged into a power strip or surge bar that limits current flow.
When the fuser unit is nearing the end of its life, problems of deteriorated printing quality, such as residual images appearing on non-printed areas or toner not fixing onto paper completely or of paper coming out wrinkled, occur. In this case, it is recommended that you replace the fuser unit with a new one.
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.
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. Copier technicians have been doing it for years since the first office copier was created.
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 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.
The fuser unit must be replaced every 100,000 pages, usually along with the transfer belt and feed rollers as part of a maintenance kit. The error code 010-351 indicates that the fuser has reached 100,000 pages and should be replaced immediately. The printer will not operate until the fuser unit is replaced.
Do not reuse a maintenance box that has been removed and left uninstalled for more than a week. Keep the maintenance box away from direct sunlight. Note: You cannot print or clean the print head while the maintenance box is full, but you can perform tasks that do not require ink, such as scanning.
Reset. Resetting the printer stops printing and clears the current print job received from the active interface. You may want to reset the printer when there is a problem with the print job itself and the printer cannot print successfully.
The maintenance box stores ink that gets flushed from the system during print head cleaning. When an ink cartridge is expended or the maintenance box is at the end of its service life, you need to replace it.
Toner is the powder ink that latches on to the paper to create text and images. It is stored in the toner cartridge. An image drum is the unit that copies the text and images from the computer and then transfers them to the paper, along with the toner.
Color Laser Printer or Black & White Laser Printer

As print quality goes down over time, this will be a reason to replace the color printer. We find a black and white printer can sometimes last 10 years or more and most color laser printers are replaced every 3 to 5 years.

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.
The toner is rolled onto the substrate as it passes the drum; toner particles with negative charge get attracted to the paper with the positive charge and thus produce the desired image. The fuser unit or hot roller is used to melt the toner powder, which is essentially plastic, onto the paper.
