Service Note for HP LaserJet P4014 P4015 P4515 Fuser Assembly Replacement


DO NOT INSTALL OR REMOVE FUSER BEFORE TURNING POWER OFF. Failure

to power down before installing or removing fuser will void warranty

Your HP P4014/P4015/P4515 fuser has been built to the highest quality standards.

If you are experiencing problems with this fuser (jams, noises, poor print quality,

etc.), please observe the following:


If the fusers 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

feed/separation separation rollers (one in the paper tray and two in the bottom of

the printer) and three MP tray rollers. 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 54lb. For trays two to six, the paper must be between 16lb and

36lb.


Other Helpful Resources


If your printer’s motors and fans run continually without printing any pages, and

with “PROCESSING JOB” displayed on the control panel, along with a possible

“41.08 ERROR”, the printer’s firmware may need to be upgraded. Firmware

versions lower than 04.060.7 will exhibit this problem and can be resolved by

visiting http://www8.hp.com/us/en/support-drivers.html and downloading and

installing the current firmware revision. See Instructions on opposite side.


Other Symptoms Of Outdated Firmware

 Jamming without cause

 # 49.xx errors

 Printer stays in "Processing Job" and is slow to print or never actually prints

 Poor fusing/ poor images quality

Be certain that both sides of the fuser are firmly locked into the printer. Listen for

the two locks to snap in when you install it. If the fuser is not secured, the printer

may display a “50.3 FUSER ERROR” message or you may hear a grinding noise. In

either of these cases, remove the fuser and reinstall it making sure that both sides

are locked in place.
