I recently installed ubuntu 18.04. I installed the Seiko scanner program per their instructions. I checked it using terminal and the Bash command "lsusb" and the hardware detects the scanner. I use "Classic menu indicator" and it sees the scanner program; however, when I click on the program name, "image scan!for Linux" I get a message "could not send command to scanner. Check the scanners status". Does anyone have a solution for this problem?

Add a link & a file

The problem stems from missing symbolic links in the /usr/lib/x86_64-linux-gnu/sane (or, more generically, /usr/lib/$(uname -m)-linux-gnu/sane) to the Epson driver directory.

$ sudo ln -sfr /usr/lib/sane/libsane-epkowa* /usr/lib/x86_64-linux-gnu/sane

Furthermore, a 55-epson-libsane.rules file needs to be added to the /etc/udev/rules.d/ directory with the following contents:

    SUBSYSTEM=="usb", ENV{DEVTYPE}=="usb_device", MODE=="0666"
    SUBSYSTEM=="usb_device", MODE=="0666"

ATTRS{manufacturer}=="EPSON", DRIVERS=="usb", SUBSYSTEMS=="usb", ATTRS{idVendor}=="04b8", ATTRS{idProduct}=="*", MODE="0666"

ATTRS{idVendor}=="04b8", ATTRS{idProduct}=="0137", MODE="0666", GROUP="scanner", ENV{libsane_matched}="yes"

After power cycling the scanner, the following command should now properly list the connected scanner:

$ scanimage -L

device `epkowa:interpreter:003:002' is a Epson GT-S50 flatbed scanner

Use xsane or the proprietary Epson iscan to operate the scanner.

  • This also helped me with my Brother MFC-7340 scanner. The same issue with links. https://askubuntu.com/a/1054065/54548 <= This answer has the details for that scanner brand. – fbicknel Mar 14 '19 at 19:47

    Just want to say thanks for this. After spending a few days on google searching for an answer this worked! I have an ubuntu 18.04 machine with an epson v370 photo scanner. This got it to work! thank you! – Walter Jun 06 '19 at 17:22

This recent thread seems to provide the answer:

Epson GT-S50 scanner not working after upgrade to 18.04 from 16.04

Two parts:

  1. Create symbolic links
  2. Add a 55-epson-libsane.rules file to /etc/udev/rules.d/

The symbolic link is:

sudo ln -sfr /usr/lib/sane/libsane-epkowa* /usr/lib/x86_64-linux-gnu/sane

and the above thread gives more details on part 2.

For the 32-bit system use this symbolic links:

sudo ln -sfr /usr/lib/sane/libsane-epkowa* /usr/lib/i386-linux-gnu/sane

and rest like previous answers
