If you see this error upon starting iScan aka "Image Scan for Linux":
“Could not send command to scanner. Check the scanner’s status.”
It means the iScan couldn't find the scanner. This happens often if it's not connected via USB, but lives in a wireless network for instance.
Do the following:
cd /etc/sane.d/
sudo gedit dll.confThis will open the main configuration file for the SANE dynamic backend loader.
Ensure these entries are listed and uncommented inside the configuration file:
epkowa net
Take note of any other entries referencing Epson. Having them commented or uncommented can help troubleshooting later if iScan can't still connect.
Ensure that /etc/sane.d/epkowa.conf is properly configured. Normally you could use net autodiscovery value but that might not work:
net autodiscoveryIf that doesn't work you need to assign a fixed IP to the scanner unit and add it like so in the epkowa.conf configuration file:
net 192.168.xx.xxNote that this is obviously an example address. It's normally a local address value.
Save the files and check if now iScan connects. If you still have issues ensure you have downloaded the latest drivers from Epson: http://download.ebz.epson.net/dsc/search/01/search/.
You can also try commenting/uncommenting other Epson values from the dll.conf file.

Now, on my end I am using a wireless scanner, and it has a scan button.
I'd really like to know how I can make use of the scan button with imagescan
I read there is a service called Epson Network Monitor supposed to trigger the software when the button is pressed, but I don't see a linux version or any info about this service.
If anyone knows anything about this, I'd love to figure this out.
