Seems that my WorkCentre 3225 s/n 3381263150 linux driver is incompatible with ubuntu 20.04 LTS simplescan or xsane.
I ask to xerox to port the unique linux driver present on xerox download page to work with Ubuntu 16.04 LTS Xenial Xerus
This is a peer to peer forum, Xerox and its Engineers do not come here and if they do, they don't make decisions based on it. You need to call their support line to lodge a complaint or to ask for a FER (Feature Enhancement Request) to get something developed. The FER isn't a guarantee or promise, it is just a suggestion you can make, you can pay to have a driver developed through them as well, but you must call, not email or post here to get it done.
