Configuring an Epson Perfection 1670 scanner
Updated 8 Août 2019
To work with scanners in GNU\Linux, you will need the API developed by the [SANE] (http://www.sane-project.org) project. The project website includes a page with all [supported devices] (http://www.sane-project.org/sane-mfgs.html); as well as reports of how specific devices respond. Necessary backends are also to be found there. For this model, support is provided by the snapscan backend.
Calculate Linux Desktop comes with SANE and XSANE (graphical interface for SANE) installed by default, but if your system does not have these, use the following command to install them:
emerge -a media-gfx/sane-backends media-gfx/xsane
KDE users may appreciate the kde-apps/libksane package, which provides integration with the SANE interface.
Detecting the scanner
Make sure that your system sees the device:
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 006: ID 04d9:0169 Holtek Semiconductor, Inc. Bus 001 Device 005: ID 05e3:0608 Genesys Logic, Inc. Hub Bus 001 Device 003: ID 046d:c077 Logitech, Inc. M105 Optical Mouse Bus 001 Device 004: ID 041e:4053 Creative Technology, Ltd Live! Cam Video IM Bus 001 Device 002: ID 0424:2514 Standard Microsystems Corp. USB 2.0 Hub Bus 001 Device 002: ID 04b8:011f Seiko Epson Corp. Perfection 1670 Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
This command should output a list of USB connected devices, including the name of your scanner.
Else run the following command:
dmesg | grep error
If you see something like this:
usb 2-9: device descriptor read/64, error -71 usb 2-9: device not accepting address 9, error -71
please check your cable connection. Some devices require a high-speed connection to a USB 2.0 controller.
sane-find-scanner to display the detected scanners. You should see something like this:
found USB scanner (vendor=0x04b8 [EPSON], product=0x011f [EPSON Scanner]) at libusb:001:002
You may of course have a different USB bus (libusb:001:002).
Some scanners will not work without firmware. We also need a firmware. Firmwares are not included in the distributed version of SANE for licensing reasons, but in most cases they are available on the vendor's website or on the CD that comes with the scanner. In other words, we have to install drivers for Windows. You can download them on the official site. Look for in the driver archive. You will need the
cabextract tool to work with it:
Go to the drivers' directory and run:
Look for in the extracted files: this is the firmware you need.
Then copy the firmware file to and edit the configuration for the relevant backend. Open and edit the firmware line:
Then turn off the scanner, disconnect the USB cable from the scanner, reconnect it turn on the scanner. You can now launch XSANE, from to begin with. If you have only a scanner and no other equipment (tuner or webcam), a device selection dialog will appear when you start
xsane. Select your "EPSON Scanner1" and press . Wait a bit for
xsane to start. If this does not happen, you will most likely see an error message. If it says "Invalid argument", something is wrong with your firmware. An error message containing "I/O" probably means that you are having problems when trying to access the device. If all is OK, an application window will open. You will be finally able to use your scanner.
As working from root is not the best option, we recommend that you add scanner users to the group:
gpasswd -a user1,user2 scanner
