I can tell its not an issue with the scanners themselves as they work normally when operated manually and I don't think its a firewall issue as I have both wiped clean its connection rules and added rules that should allow communication from and to the machines from any port and the end result was the same (no scanning from PC). I used Wireshark to try and findout what is happening, and for VueScan the mDNS queries with the questions about available services aren't fully answered (it asks for both printer and scanner services, but the mDNS responses only show answers for printer services). However the printing function works without any issue in all of them. I am also not finding anything useful w/ DuckDuck.I'm trying to access the scanner functionality of some Ricoh All-in-One printers from a workstation with Debian Stretch using Vuescan, but none of the means I've used can find any of them: neither scanimage nor sane-find-scanner detect them even with the net backend enable from conf files simple-scan, xsane and VueScan either show an error message telling me there are no scanners available or lock and the avahi-daemon can't detect any _scanner._tcp or _uscan._tcp services. My guess is that I'm missing some sort of driver but am not seeing anything on either Xerox support or the Debian repository. I found a mention of 'TWAIN' compliant software in an article but I can't find anything in the repository searching for that. which unfortunately have only gotten the suggestion to contact Xerox support as a response so far. However both Xsane and Simple-Scan report that no scanners are found.

I have installed Xsane, Simple-Scan and the scanner backend software listed in the Debian Linux repository.

I have been given a Workcentre 3220, and have it on my home network, both of the PC's can see it and print to it.
