sane
This is the machine behind scanning on ubuntu.
Install the ppa
sudo add-apt-repository ppa:sane-project/sane-git
If you have the old one you need to
sudo ppa-purge ppa:rolfbensch/sane-git
Then update and upgrade.
Scanner not found or "device busy" error
This can be because someone else has the scanner locked since they are using it
It can be because the usb info is not properly in the sane.d config files.
For example you can run.
sudo sane-find-scanner
Then look at the info for the scanner. It needs to appear in a config file.
For us we needed to add the MG3600 like this in /etc/sane.d/canon_dr.conf
# MG3600 series
usb 0x04a9 0x178a
gscan2pdf
Brilliant program
gscan2pdf
NAPS2
This is a great cross platform and free application.
Does a fantastic job straightening scans that are skewed a bit due to the doc feeder.
Scanning over the network
This can be very tricky.
At the bottom of the /etc/sane.d/saned.conf you need to add:
192.168.2.0/24 (change base on your network but the last 0/24 is same)
Somewhere in December 2020 this broke.
On the machine serving the printers you need to purge ippusbxd
Now we need to install the debs for airscan and ipp-usb
In the file /etc/sane.d/net.conf you need to add hosts to attach to
newi3
192.168.2.100
And change the timeout to about 20 seconds.
connect_timeout = 20
If your scanner is behind a firewall you may need to open the sane port.
sudo ufw allow 6566
As you see the host can be a LAN IP or hostname if in /etc/hosts
Reboot.
