Troubleshooting The HP 4300 Laserjet 50.3 Fuser Error
Step one is to turn the machine off and let it sit 10 to 20 minutes allowing the printer to cool down to a point where it might work again once plugged back in.
Step two in troubleshooting the 50.3 fuser error is to check for proper ventilation around the machine while your waiting for the machine to cool off. The vents on the side of the machine are for the fan inside. If the vents are blocked then the machine cannot dissapate the hot air inside resulting in heat issues.
Step three is to check the fuser mode through the control panel. The fuser temperature can be adjusted to help with certain types of media. If the fuser temp is not configuired to the media inside the machine the fuser can overheat resulting in an error state.
Step four is to check your print jobs. If the machine displays the error code during a large print let the machine cool off and try the print job again but break it down in smaller jobs to allow the machine to periodically cool off.

This allows the machines memory to clear out so any error that might have been stuck in the machine to be totally gone so when you turn it back on it should go through its normal power up sequence. If that fails to work or you see the error happening more than just once then replacement of the fuser is the next step. Below are instructions on how to replace the fusing assembly and just below is a link to purchase a fuser if needed to help resolve the 50.3 fuser error in your HP laserjet 4300 printer.
