Returning to my reply back in post #8: Again, check that dll.conf contains an uncommented 'hpaio' entry on the host where scanning is not working.

Don't see one.
Code:
/etc/sane.d $ cat dll.conf
# /etc/sane.d/dll.conf - Configuration file for the SANE dynamic backend loader
#
# Backends can also be enabled by configuration snippets under
# /etc/sane.d/dll.d directory -- packages providing backends should drop
# a config file similar to dll.conf in this directory, named after the package.
#
# The next line enables the network backend; comment it out if you don't need
# to use a remote SANE scanner over the network - see sane-net(5) and saned(8)

I assume that you compared the file with the host where scanning is working? If it really is missing, add the entry.

Do you know the IP address of the multi-function device? If so, see if you can detect and communicate it as explained via the page linked to below...

From reading this Linux Mint thread and checking my own system (I have HPLIP installed but don't own such hardware), I note that HPLIP supplies a file /etc/sane.d/dll.d/hpaio...
Code:
ls -l /etc/sane.d/dll.d/
total 8
-rw-r--r-- 1 root root 6 Nov 18 18:30 epkowa.conf
-rw-r--r-- 1 root root 6 May 31 01:59 hpaio
This file contains 'hpaio'...
Code:
cat /etc/sane.d/dll.d/hpaio
hpaio
Perhaps you have the same? In any case it can be added manually if required. |

If you have hplip installed, do you know the version? It may be located in /etc/hp/hplip.conf.
If not installed it is available here.
If you do, then you can get the hplip plugin that manages the scanner directly from HP
You need to be sure the version of the plugin matches the hplip running version, but in my experience the only way to scan with an HP MFP is by having the plugin installed. Hplip only talks to the printer, the plugin allows it to talk to the scanner. Mine is installed from the distro repo and every time they update the hplip version in the repo I have to also manually update the plugin to match (the plugin is proprietary).
I install both hplip and the hplip gui by default, plus the plugin. The only thing I have ever needed to be able to talk to my network printer during setup and printing was the IP address of the printer to use during setup. As long as the printer has a static address it should just work.
Since you say that you can print but not scan I think installing the plugin is the only thing needed. |

When you list the directory contents and see that there is no fie called hpadio, there is little point in then doing 'cat /etc/sane.d/dll.d/hpaio' You have a named 'hplip' fie present (both hosts), so I would expect to see that they have the 'hpaio' entry within.
Code:
cat /etc/sane.d/dll.d/hplip
Some suggestions:
1. As per the advice I gave (arhwiki page I linked to)in post #21, try understanding and running the commands there, and see whether you can get the scanner to work (as per those instructions given in that archwiki page). You will need to know the IP address of your HP device of course.
2.You could try running the HPLIP diagnostic utility, to see if that shows any obvious differences between your working and non-working host...

Tried to attach .txt of hp-check for working and non working but got error - invalid file. 12.6 KB each.
Both had lots of errors. As I remember 2 years ago I had to add the printer from the printer instead of from the printers gui

Meaning the networking had to be setup from the printers control panel instead of from the computer.
