HP Laserjet P4014, P4015 printer is constantly saying “processing print job” or their machine is printing extremely slowly.  First try printing from different paper trays.  In most common cases this only happens when printing from Tray 2. So if you run into this issue try loading tray 1 (MP tray) and see if that works correctly. If it does then we know we have a DC controller/fuser problem. Tray 1 prints at half the speed of tray 2. The error is a result of a power and timing issue between the fuser and DC controller. Generally, as fusers age, they draw slightly more power and take more time to warm up to the correct temperature. Given the error situation it seems the fuser temperature is outside the printing temperature as the DC controller tries to print this puts the printer in a continues loop. Tray 1 works because it prints more slowly allowing the fuser to reach it correct temp before the DC controller starts other processes in the machine. Replacing the fuser should fix the issue but there is also an upgrade to the firmware on the DC controller. Replacing the Fuser unit and upgrading the firmware simultaneously will resolve this issue.
