It is my first time to upload a question in this community. I don't know about much on the linux system or network, so it maybe a silly question for experts. Sorry about that in advance.
My situation is as follows: I am now running Ubuntu 16.04 as an operating system of my laptop. And my office has a scanner(actually, it is a multifunction printer/scanner "imageCLASS MF4870dn") made by Canon. The scanner has an IP address in the form of xxx.xxx.xxx.xxx. I would like to use the scanner as a network scanner using the IP address. But it fails.
I refered to the following pages.
I expected that this is a right solution for me. Especially, I thought that the "backendname" for the scanner is also "pixma". I followed the first answer there, almost in the same way. But I faced the error message when I typed "service saned start". The error message was "Failed to start saned.service: Unit saned.service is masked".
So I googled the error message and I could find the solution there. I followed the solution, and sane seems to be active when I typed "sudo systemctl status saned.socket". But the same error message comes again even after I reboot my laptop.
I also read the manual for sane https://help.ubuntu.com/community/sane but it was not very helpful for my problem. How can I resolve this problem and use the network scanner?
sudo systemctl start saned.socket && sudo systemctl enable saned.socket && sudo systemctl status saned.socketlast part should show it is no longer masked. – Rinzwind Feb 22 '18 at 09:33
