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.
Push up on the release buttons on both sides of the fuser to release the springs, and then pull the fuser out of the printer. Place the old fuser aside for recycling. Remove the new fuser from its box. Remove the protective packaging.
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.
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 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 unit is a periodic maintenance part and should be replaced to maintain optimum print quality and reliability and to prevent paper jams.
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. The speed at which the paper passes through the fuser is what keeps the paper itself from burning.
In reality, there`s not a whole lot of difference between fuser kits and printer maintenance kits. 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.
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.
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.
The Fuser operates in the temperature range of 175 – 215o C (347-419o F).
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. humidity and/or paper condition and storage.

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).
Fuser kits replace the heating element in Laser printers that fuses toner onto paper. These elements wear out from normal use, and many printers need a new fuser every 60,000 pages.
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.
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.
This error displays because the Fuser Unit cannot maintain a normal operating temperature. Power the printer off and then on. If the problem persists, contact Support for additional assistance as the Fuser Assembly may need to be replaced.

While ink is standard in most conventional inkjet home printers, laser printers depend on toner and lasers for their output. Given that they`re based on their own unique technology, you`ll find that they also have their own unique advantages and disadvantages.
The difference between leaving your printer on or turning it off is generally insignificant in terms of energy costs. For healthier print heads and more efficient ink consumption, however, it`s better to leave your printer on.
Paper Jams

This is a common laser printer problem. Primary causes include grime, dust, worn rollers, or incorrect paper weight. The most basic way to prevent paper jams is simply through regular cleaning of your printer. Also, replace parts as needed.

If you keep the printer turn on for long periods of time, it will not have much of an effect on the printer`s components. It does not cause the printer to malfunction. If you want to reduce your electricity consumption, you can avoid keeping your laser printer on all the time.
