50.1 Fuser Error – HP Color Laserjet 4700, 4730, CP4005 Printer Repair
50.1 fuser error – HP Color Laserjet  4700, 4730 MFP, CP4005
Like the 50.2 fuser  error the 50.1 fuser error in the HP color laserjet  4700, 4730, and CP4005  is more likely to happen than other fuser errors. The 50.1 fuser error means the thermistors inside the fuser have sent a signal to the DC controller that the temperature inside the fuser is to low to properly bond the toner to the paper. To avoid print quality and paper jam issues the machine shuts down and displays the error on the control panel. First thing to try is turning the machine off and back on. Second is  to verify the machine is plugged straight into a wall outlet and not a power strip or battery back up. Finally, turn the machine off and let it sit 10 to 20 minutes. This step allows the machines boards to discharge so if an error code has stuck in the machines memory this will allow it to clear itself. If all else fails then reseating it could resolve the issue. Below is the instructions to perform this action.

I replaced the fuser on a hp 4700, it worked for a while but the fuser went bad again. Could it be that this was a poor quality fuser? Or is there a fuser cooling fan that is not working, so the fuser is overheating?
