ok, if you could provide me with a link to the Sane man (main?) page, I will attempt to do all that I can understand - is this it?: http://www.sane-project.org/
man is short for manual! It's the old Unix Manual, which is baked into Linux, into all Unix systems. You don't need a browser or a url for that! Just open a terminal, type man sane and you'll get the page I told you about. Page through it and you'll find the troubleshooting section. Similarly man sane_hpaio will give you a man page on debugging the hpaio scanner driver in particular. To learn how to read man pages in general use man man.

Code:
michael@michael-HP-EliteDesk-800-G1-SFF:~$ scanimage -L
device `hpaio:/usb/HP_LaserJet_Pro_MFP_M127fn?serial=CNB9H7FDXQ' is a Hewlett-Packard HP_LaserJet_Pro_MFP_M127fn all-in-one

So scanimage finds it after all. That suggests you shouldn't have a problem. Try scanimage>outfile.pnm then see if that file will display in a viewer.
Make sure your user is in the scanner group, Ubuntu has a history of not adding users to that group.
To list what groups you are in run the 'groups' command.
Thanks for your reply.
Could you, or someone, please tell me how to do this....
Ok, and did you run 'hp-doctor' yet? That might provide more useful information, along with hazel's diagnostic advice.
Code:
michael@michael-HP-EliteDesk-800-G1-SFF:~$ hp-doctor

Considering this, that it finds it, do you still recommend that I figure out the "man sane" (?)
p.s. to all: The scanner worked fine up until the clean install of Ubuntu 22.04 lts
