Samsung SCX-4623F Networked

[carlnielsen]

I have a Samsung SCX-4623F attached to a "server" running OpenMediaVault. I have 2 laptops on the network:
1. Linux Mint XFCE 17.3 Rosa
2. Linux Mint Debian Edition (rolling updates based on Debian Testing)

All 3 devices have driver-4.00.36 installed.

Laptop 1 was setup quite some time ago and works perfectly for printing and scanning. Laptop 2 was more recent and can print without trouble but xsane cannot find the scanner when I try.

I have recently added a 3rd laptop to the system also running Mint XFCE but version 18.3. I installed the same packages but it, like the LMDE laptop, reports that it can't find the device.

Any troubleshooting advice? Logs I can check?

Is there anything special to do to get a scanner to work across the network on the client device apart from installing the relevant packages. I know to print, one must then add the printer in CUPS etc, but for scanning?...

All help appreciated.
