simple scan, or any other scan prog not working on Hp Laser MFP M28

I cannot get my scanner to work on 18.04 and my HP Laser MFP M28 ... it prints fine but will not scan. I read another post and tried some of the commands suggested and this is the result, but since I am linux challenged I do not know what to do from here. Any help is appreciated. This is a listing from my terminal.

  # No SCSI scanners found. If you expected something different, make sure that
  # you have loaded a kernel SCSI driver for your SCSI adapter.
