The fuser unit is a vital component of laser printers. Most fusers last between 50,000 and 200,000 pages, depending on the design.
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 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.
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.
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 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 unit is a periodic maintenance part and should be replaced to maintain optimum print quality and reliability and to prevent paper jams.
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.
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.
The Fuser operates in the temperature range of 175 – 215o C (347-419o F). Temperature will vary depending on the type of media selected.
This is accomplished by the fuser lamp. The lamp operates at 120VAC or 250VAC and is typically rated at 500W to 600W. The control signal from the heater control circuit is typically low voltage (< 9VDC).
The following are the top reasons why paper jams occur:
unsupported paper/media is used. incorrect paper settings in the tray and/or the print driver. paper loaded incorrectly and/or paper edge guides not adjusted properly in the tray.
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 grease is used to lubricate fuser film sleeves. It is critical to apply grease properly when replacing fuser film sleeves, and it is also important to apply the right type of grease.
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.
Your printer monitors the life of your fuser. When the fuser reaches the end of its life, the printer displays 80 Fuser Exhausted. This message indicates it is time for you to replace the fuser. For best print quality, make sure you replace the fuser when the printer displays 80 Fuser Life Warning.
Depending on your printer model, the fuser unit may be sold separately or it may be included in the printer`s maintenance kit. The fuser melts the toner particles, binding them to the page.
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.
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.
