Greetings and Welcome to the HP Support Community.
Don't worry, I'm here to help!
Er/01 error message occurs when the input tray is empty. To resolve the error, load paper into the input tray.
Refer to this document for instructions to load the media - Loading Paper, Envelopes
For error codes and their solution, refer to this document - HP LaserJet Pro M28-M31w Printers - Blinking Lights
Hope this helps!
Let me know how that goes.
