HP LaserJet 4000/4050 Fuser

 

Your HP 4000/4050 fuser has been built to the highest quality standards. If you are experiencing problems with this fuser (jams, noises, poor print quality, etc.), please check the following areas of the printer:

 

Use only the screws provided to secure the fuser in the printer. Be certain that both screws are tightly securing the fuser to the printer's frame, allowing for no play or looseness.

 

If the fuser's sleeve does not spin when you manually turn the gear, please do not assume that the fuser will not run in the printer. At room temperature, the grease applied inside the sleeve thickens and may actually prevent the sleeve from spinning. When the fuser is installed and run in the printer, the grease will heat up and attain proper viscosity.

 

If you continue to experience paper jams after replacing the fuser, replace the two separation rollers (one in the paper tray and one in the bottom of the printer) and four D-rollers (in the bottom of the printer). Ensure that the paper you are printing on is within the specifications allowed by HP. For tray one/MP tray, the paper must be between 16lb and 53lb. For trays two to four, the paper must be between 16lb and 28lb.

 

If you continue to experience poor print quality/image defects after replacing the fuser, replace the toner cartridge and/or transfer roller. Remove the toner cartridge and vacuum or blow out any dust and toner from inside the printer.
