Answer:-- The reason is as follows:-- A 50.4 error message on some of the newer HP LaserJet printers indicates a problem with the power supply.-------------
If the printer is connected to a UPS, disconnect it, or disconnect it from a power strip and plug it directly into a wall outlet. A laser printer should never be plugged into a UPS, because the UPS can be damaged by the surges of power required by a printer to keep the fuser assembly warm. If that doesn’t work, make sure that all of the components in the printer are seated properly.this will help.
