Power printer off one to two minutes. Open doors and covers and remove the toner cartridge. Make sure there is no paper jammed in the printer. Pay close attention to the area where the toner cartridge sits. The main motor is located just to the left of the toner cartridge. If either the 936 error or the 937 error returns after you power on the printer or when you try to print, the printer will require service. The main motor assembly may need to be replaced.
