Troubleshooting The HP 4240, 4250, 4350 laserjet 50.3 Fuser Error
there are several thing to  check when  troubleshooting the 50.3 fuser error in the HP laserjet 4240, 4250, and 4350 printer. First is to turn the machine off and let it sit for 10 to 20 minutes. thus allowing the fusing unit inside the printer to cool off. After it has cooled off then turn it back on and see if the error comes back. Second thing to check if the first step didn’t work is to look for proper ventilation. Make sure no books, folders, or post it notes are leaning against the machine and not blocking the vents on the side of the machine.  Obviously, the fan and vents inside the machine allow  extra heat to escape the fuser and  let the machine cool down properly.  Third thing is to check the fuser mode settings. I’ve personally had to adjust the printer temp on some machines to correct issues with certain types of media. By doing this you could cause an overheat issue if another media type is installed without changing the current temperature settings for the fuser. To check fuser settings go into the information menu and print off the menu map. With the menu map you can look through the menu structure of the machine and work your way through the fuser settings. fourth thing is the enviroment. Make sure you are not using this machine in temperatures that reach over 85 to 90 decrees. If the heat outside the machine is too high again it doesn’t allow for correct cooling of the machine resulting in the 50.3 fuser error.
