HP Laserjet MFP m28-31 will not scan

Running Mint, 19.1
The printer is brand new, I installed it yesterday:
Loaded and installed latest HPlib
simple scan requested plugin - installed
 all functions worked perfectly yesterday.

This morning printer still prints and photocopies, but scan request seems to wake up machine/start scanning then error:
"failed to start scanner: Error during device i/o"

I really need some help quickly, I am trying to scan images for display at my fathers funeral!!!!!!
