iscan for linux can’t find my printer (originally published 2014-02-11, updated 2017-01-02)

Epson’s iscan scanner app

Fixing the config files

iscan error dialogIt’s been a couple of years now that I’ve had iscan installed. Today I wanted to do some high-resolution scanning so I thought I’d try and get it to work as I imagine it might be the best tool to interface between my Kubuntu 13.10 GNU/Linux distro install and my Epson Stylus SX535WD [update: still using same printer-scanner-copier with Kubuntu 16.04, this method still working]. That W in the model number shows I have a wireless connectable Epson. Over wifi I have no problem printing or scanning using the default tools and with the “epkowa” drivers from Epson but attempting to use iscan (“Image Scan! for Linux”) would give an error:

“Could not send command to scanner. Check the scanner’s status.”

In essence I did “sudo nano /etc/sane.d/dll.conf” and made the file there read:

# /etc/sane.d/dll.conf – Configuration file for the SANE dynamic backend loader

with no other (uncommented) entries. Previously it had an epson2 entry which I think may have been confusing things.

Then I made sure that the /etc/sane.d/epkowa.conf file new where on the network to find my printer. I gave the printer a fixed IP when I installed it, X.X.X.10 [use the proper network address for your printer, not this placeholder].

# epkowa.conf — sample configuration for the EPKOWA SANE backend
net X.X.X.10
# net autodiscovery

I’m not sure if the autodiscovery option works or not. If you don’t have a fixed printer IP then perhaps you want to try that?

FWIW sane-find-scanner still doesn’t work even after this fix is applied. The same error window will still be shown by iscan when the printer is turned off.

iscan with GIMP2

Lastly if you’re using GIMP2 then iscan works as a plugin provided you have a link in place in the plug-ins folder:

ln -s /usr/bin/iscan /usr/lib/gimp/2.0/plug-ins/iscan

Alternative scanning options

Before I got iscan working I used Xsane (multi-window), Skanlite, scanimage and AcquireImages with varying degrees of success.

As usual if anything in this post has helped you fix a problem with your own system then please add a comment to make the page more useful to others, thanks.

This method is still working for me. The link for the Epson printer file downloads has changed and in particular the iscan 1.0.4 bundle is the current one. Despite the UK Epson site initially telling me that my printer doesn’t work for Linux and doesn’t have available drivers a little digging leads to this install instruction for “Image Scan” page which some may find useful.

My Kubuntu install gave an error:

(iscan:24091): Gtk-WARNING **: Unable to locate theme engine in module_path: “adwaita”

Which was removed by doing sudo apt install gnome-themes-standard.

It’s not often I discover a gem like this, I was about to give up after searching high and low on the Net for exact iscan message “Could not send command to scanner. Check the scanner’s status . OK” So a big thank you, Seiko Epson should highlight this in their otherwise decent Linux driver download pages. My home Wi-Fi inkjet MF printer is an EPSON XP-405.

Following your instructions (except using Geany to edit two config files) iscan or Image Scan! for Linux 2.29.3 ran first go from Crunchbang 11 Run Program dialogue box on a 2008 ASUS EeePC Netbook 1000H. I find iscan scan quality far preferable to generic xsane, and the link already existed in the GIMP 2.8.2 Plug-ins folder so was able to test the GIMP File menu Create > Scanning (iscan)… option too on this EeePC Netbook.

Only issue still is unable to select from the Epson XP-405’s LCD panel to scan to local PC as it cannot find it on network. Similar problem often arose when this same Netbook PC ran default Windows XP but disconnecting the PC and reconnecting the PC refreshed the XP-405 and it could then see the name of the Netbook PC and scanned from then on for the session. EPSON drivers for Linux seem unable to talk to the XP-405 for the scan function in the XP-405 scanner’s firmware, which I find puzzling when this XP-405 scans so well when instructing the XP-405 to scan from this Netbook PC using iscan.

Glad it helped you. Sorry I don’t have any insight WRT the network connection: the only idea I’d have is to make sure that your printer and computer have fixed IP addresses rather than using NAT. That helped me anyway. It’s also possible that something like efw [firewall] is blocking probes from the printer to the local network that would normally allow the printer to find the PC? [I think that’s what you meant, these things are quite hard to put in to words sometimes].

Thanks man! This solved the issue for me. It didn’t work on autodetect, but it worked on an IP address immediatel. (XP-312 on Mint 17)

Thanks. This message helped me to make my new Epson WorkForce 2660 to scan using iscan under Ubuntu 14.0.4 LTS.

Great stuff!

I too had this problem.
It was epkowa.conf file and the net entry.
I decided just to use the DNS entry for the printer that the router had rather than fix an IP address. Both ways work great.

Thanks for the info

I used this to get my scanner working on the net. Thank you. I am embarrassed to say that I read the Iscan documentation afterwards and it tells the whole story (RTFM, eh):

Setting Network Plug-in
1.Connect the scanner to the network and set the IP address.
For information on how to set the IP address, refer to the user
manual shipped with your scanner.
2.Please enter the information on your scanner in /etc/sane.d/
epkowa.conf by using root privileges.
How to enter the information:
net [IP address] [port number]
net [ host name] [port number]
Note: Please set [port number] to 1865.
Entering a port number is optional, so you can omit it. However,
you must enter an IP address port number.

All that was necessary was to modify epkowa.conf and all was well.

Kind regards

Thank you very much man, your guide helped me to resolve the problem with my Epson WF 4630. It worked for everithing with others software but not the front and back scan.
Iscan wont open…now it does and the scan front+back with iscan works.

Thank you man

Not that often a correct solution to a problem is found on the internet.
Have that man stuffed and mounted.

Only works for me when launching iscan from the command line as root:
$ sudo iscan

Thank you very much for this information on getting the epson scanner to work. I had it working in another Linux Mint OS but put in a new SSD drive and had to reinstall the newer version of Linux Mint and it had the problem that you cured for me by using you write up.

Again Thank you very much

Thank you, it works on Ubuntu 15.10. FYI the “net autodiscovery” option does not work for me.

Well I tried everything for my Epson XP-625 all in one, and at the end of the day what made the scanner work was simply putting the Ip address of the printer in epkowa.conf, without net before and without 1865 after, just plain and simple ip address in epkowa.conf nothing else.
