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.

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.
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.
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.
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.
Look inside the fuser opening to make sure there is no debris or jammed paper. Remove any debris or jammed paper, if found. Hold the handles on each side of the fuser and reinstall it in 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.

HP Laserjet 2200, Tray 2 Pickup Problem, Gears Clicking
ANSWER : Definitely not a solenoid problem. I’ve worked on tens of thousands of printers and never replaced a single solenoid. You probably knocked something loose when you installed the pickup roller. Maybe something to do with the gear on the end of the pickup roller shaft. You’ll need to take the gear assembly off to be able to see it.
