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).
An image drum is a critical component of a laser printer that transfers toner and image or text to paper. It`s also known as the image unit, drum unit, or photoreceptor drum, among other things.
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 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.
Increasing the temperature too much may distort the paper and cause glossy lines, paper jams, and insufficient toner fusing (hot offset). Depending on the type of paper, you can increase the toner gloss by increasing the temperature by 5 to 10°C over the initial factory setting.
This feature is accessed from Machine Status > Tools > Setup & Adjustment > Custom Paper Settings. Select the desired Custom Paper > Change Settings > Adjust Fuser Temperature > Change Settings.
Use an activated toner cloth, stretched tautly, and carefully wipe down the drum exterior to remove loose toner. Then use a cotton ball saturated with 99% pure isopropyl (rubbing) alcohol. Clean any patches of stubborn toner still attached to the drum. Use toner cloth or lint-free microfiber to clean the print rollers.
The most obvious is most common on laser color printers and can be detected by a flashing message on the printer display screen. Other signs of a bad printer drum include printing blank pages, printing gray pages and strange sounds coming from the printer as it prints.
The Fuser is the piece that fixes the toner on the paper. This, like any other consumable part, wears out with the regular use of prints, since it is one of the components that suffers the most due to its mechanical wear and overheating of its components, due to the high temperatures it must withstand.
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.

ANSWER : I have the same problem. please help
ANSWER : You can buy just the upper fuser roller that is the cause of your problem. The real problem is that there are no instructions for rebuilding the fuser. The Brother fusers are a bit difficult to take apart.

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.
