The Fuser. The fuser unit is a vital component of laser printers. Most fusers last between 50,000 and 200,000 pages, depending on the design.
If you are experiencing an “50.2F. 00 Fuser error”, first turn the printer off and back on. Sometimes the error will temporarily go away with a reboot so you can print a few more pages, but usually the error reappears.
If you have NOT recently replaced the fuser or moved the printer around, then the 50.2 fuser error indicates you may have an actual fuser failure and the fuser needs replacing.
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.
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.
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 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.
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.
This error is primarily caused by a transfer alienation failure in which the ITB is stuck and unable to rotate, the SR9 sensor (the primary transfer roller disengagement sensor) has gone bad or the fuser drive assembly has failed.
xx service fuser error. The printer is displaying a 922 type Service Fuser error (for example, 922.01, 922.54, 922.99, etc.). This type of error message indicates that the fuser unit inside the printer is operating below the proper temperature.
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 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 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 Fuser operates in the temperature range of 175 – 215o C (347-419o F).
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 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 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.
Place your old fuser kit in a safe plastic bag so that any excess toner on it doesn`t leak out and stain anything. Find the location of your local Staples store by looking through your local telephone book or going to the Staples website. Take your used fuser kit to any checkout person at your Staples store.
Fuser, the part of a laser printer that melts the toner onto the medium.
This error is primarily caused by one of the following conditions: A transfer alienation failure in which the ITB is stuck and unable to properly engage the internal transfer rollers. The SR9 sensor (the primary transfer roller disengagement sensor) has gone bad. The fuser drive assembly has failed.
59. C0 = Developer motor rotation error. With this printer it usually means the product needs to be replaced. What you can try is to remove all toners and then start up the printer and see if the error appears.
If you have NOT recently replaced the fuser or heavily jostled the printer around, then the 50.7 Fuser error indicates you have an actual fuser failure (the gearing pressure is not releasing) and the fuser needs replacing.
When a 50.4F. 00 error is displayed on the control panel, it indicates that there is an issue with the fuser or the power outlet where the printer is connected. Turn the printer off, and then back on to clear the error. Ensure that the power outlet, to which the printer is connected, is in good working condition.
