The fuser unit or fuser is a critical part of any laser printer. Using pressure and heat, it fuses the toner powder onto the page to create a print, and without it, the printer cannot operate.
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.
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.
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.
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.
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 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.
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.
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.
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 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.

Samsung ML 2165 Error lights
ANSWER : Hi there, I am having the same problem. Stupidly I bought a second replacement (genuine Samsung) cartridge thinking it may have been a faulty cartridge as sometimes it deemed to work after a bit of messing around. SO NOW I HAVE ONE NEARLY NEW AND ONE COMPLETELY NEW ; ABSOLUTELY NO USE TO ME – unless I can get the printer to accept them.

Printer won't print – reassembled from an imaging unit clean..
ANSWER : You have to realize the difficulty of troubleshooting a printer that an unexperienced person has taken apart. The pickup roller issue doesn’t sound like it is a worn pickup roller. It seems more like something wasn’t quite put together and is binding the drive motor. Since I can’t hear it or see it, that would be my best guess.
