I need help with error code 5100

Alright. May I ask you if you have tried any troubleshooting yet?

When did the issue happen? Were you able to print smoothly before?

Is your printer connected wirelessly, or with wire?

Alright, thanks

1. Turn off your printer for 60 seconds or so;
   Make sure to unplug all the wires.
2. Get it turned back in after that

I am happy to hear that!
Is there anything else I can do for you?
