Ubuntu – Running a epson Scanner perfection 3170

How can I make my scanner Epson perfection 3170 running under ubuntu 11.04 ?

When I run "Simple Scan" it said:"No scanner detected".

Thanks

Edit:

after I saw suli8's anwser. I downloaded both rpm:iscan-plugin-gt-9400-1.0.0-1.c2.i386.rpm and iscan-2.10.0-1.c2.i386.rpm

both where transformed+installed with alien. I tried it twice.

After rebooting. "Simple Scan" still says: "No scanner detected".

as a note I'm copying here the original Ronok's response at http://ubuntuforums.org/showthread.php?t=1028064&page=2

1) first see where things stand Is the Scanner USB properly connected to the computer ?

lsusb



Bus 001 Device 007: ID 04b8:0116 Seiko Epson Corp. Perfection 3170 (GT-9400)

2) Check that SANE & XSANE are Present:

sudo apt-get install sane &&
sudo apt-get install libsane &&
sudo apt-get install libsane-extras &&
sudo apt-get install sane-utils &&
sudo apt-get install xsane &&
sudo apt-get install xsane-common &&
sudo apt-get install libstdc++5

3) Check That the system is upto date: System > Administration > Update Manager (or)

sudo apt-get update && sudo apt-get upgrade

4) Then lets see where things stand:

xsane

Get a Pop up Window:

No Devices available

5)
To get a list of devices

scanimage -L

No scanners were identified. If you
were expecting something different,
check that the scanner is plugged in,
turned on and detected by the
sane-find-scanner tool (if
appropriate). Please read the
documentation which came with this
software (README, FAQ, manpages).

6) See if SANE can see the Scanner ?

sane-find-scanner

found USB scanner (vendor=0x04b8,
product=0x0116) at libusb:001:007

7) open and maybe edit this file Check to see that "epson" & epson2" are uncommented (that is with out"#")

sudo gedit /etc/sane.d/dll.conf

8)(with Epson issues all roads seem to lead here) so Go to:
http://www.avasys.jp/lx-bin2/linux_e/scan/DL1.do
Fill in the form and download:
—> iscan-2.10.0-1.c2.i386.rpm
—> iscan-plugin-gt-9400-1.0.0-1.c2.i386.rpm
to the Desktop
thats your:

cd ~/Desktop && pwd

9)Get Alien
Alien allows you to convert ".rpm" files into Debian ".deb" packages, which can be installed with dpkg.

sudo apt-get install alien

10)Make the ".deb" file from the ".rpm" file (Note in the code-example the "*" takes the place of e.g: "-plugin-gt-9400-1.0.0-1.c2.i386"

cd ~/Desktop
sudo alien -d iscan*.rpm
sudo dpkg -i iscan*.deb

11)Edit the libsane-extras.rules

sudo gedit /etc/udev/rules.d/50-libsane-extras.rules

12)if it is empty add this line:

SUBSYSTEM=="usb", ENV{DEVTYPE}=="usb_device", SYSFS{idVendor}=="04b8", SYSFS{idProduct}=="0116", MODE="0666", GROUP="scanner"
13)

Edit the epson.conf

sudo gedit /etc/sane.d/epson.conf

14) add this line (the USB device ID from step #1 above) at the end:

usb 0x04b8 0x0116

15)Add yourself to the scanner group (adding the scanner group if needed)

System > Administration > Users and Groups > manage groups > unlock > add > check self

16) Do a complete Shutdown & restart the machine

17) Try To get a list of devices again

scanimage -L

device `epson:libusb:001:006' is a
Epson flatbed scanner

18)

iscan
