error codes for hp printer mp28



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.
