Different Types of HP Printer Fuser Errors 

The fuser error on your HP printer implies the increasing temperature of this part. This error is common in HP Laserjet 4250, 4350, 4240, and 5200 models. Out of all the error codes, the HP printer fuser error 50.3 is the most common. 


Here’s what different kinds of errors indicate:

  1. The fuser error 50.1 and 50.6 errors are due to the thermistor’s low temperature. 
  2. The 50.2 fuser error is because the fuser is not getting sufficient heat to begin operating. 
  3. Another error is the 50.3 fuser error, which occurs when the thermistor’s temperature is very high. 
  4. A circuit failure results in the 50.4 bad fuser error. 
  5. A low fuser temperature causes the HP 50.7 fuser error. 
  6. Users commonly see the 50.8 fuser error if the thermistor’s temperature is very high.
  7. Finally, the HP 50.9 fuser error occurs because of the wrong fuser installation in the printer. 


Other causes behind these errors are as follows:

  • You may encounter fuser errors while trying to print a paper that is incompatible with your HP Laserjet printer. 
  • If your printer temperature registers a sudden, instantaneous increase, it will lead to a loss of the fuser kit.
  • A corrupt registry in the operating system can also cause these errors. 
  • Improperly functioning printer’s power circuit can also cause these errors.
