Fuser Roller Materials
Only two types of material – silicone rubber and fluoroelastomers – have all the necessary physical properties, and these are commonly used to coat a hollow metal core to produce the fuser roller.
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.
A fuser unit is made up of two rollers; one to apply heat and one to apply pressure. The heat roller is a hollow (usually metal) tube that is heated by a radiant heat lamp suspended in its centre (so the tube is heated uniformly), while the pressure roller is a backing roller made of rubber.
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.
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.
Take a cotton swab and moisten it with 70% isopropyl alcohol. Gently rub the paper feed roller in a circular motion, using the moistened cotton swab to remove any toner buildup. If needed, replace the cotton swab with a fresh one to ensure effective cleaning.
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). Temperature will vary depending on the type of media selected.
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 75,000 pages and as a result has 25% life or less remaining.
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 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.
Pickup rollers, often called feed or separation rollers, are used to pickup the paper from the tray and feed it to the printer. Separation pads are made to assist the pickup rollers by applying tension so that the paper is pushed to the printer.
