I'm assuming that the error msg that you typed is a typo. And you meant to type 55.1

55.1 is a DC Controller failure. Turn the printer off for at least 30 seconds. Turn it back on. After it initializes, try to print. If it fails again, you are going to have to replace the DC Controller

50.2 Fuser Error Turn off then on Description 50.2 Slow fuser error. The device has experienced an internal hardware error. Action

1. Turn off the device, wait at least 25 minutes, and then turn on the device.
2. If a surge protector is being used, remove it. Plug the device directly into the wall socket. Use the power switch to turn on the device.
