    Can't find scanner

    I'm new to Ubuntu and I have no idea how to get my scanner to work.

    It's a Fujitsu fi-4340C ADF duplex scanner.

    I installed Xsane from the software center, but it couldn't find the scanner.

    I typed sane-find-scanner in the terminal and got the following result:

    Code:
    $ sane-find-scanner
    
      # sane-find-scanner will now attempt to detect your scanner. If the
      # result is different from what you expected, first make sure your
      # scanner is powered up and properly connected to your computer.
    
      # No SCSI scanners found. If you expected something different, make sure that
      # you have loaded a kernel SCSI driver for your SCSI adapter.

    Re: Can't find scanner

    Is it a USB scanner? May sound like a silly question, but ...

    Try this command:

    Code:
    sudo sane-find-scanner
    ... and if that doesn't work:

    Code:
    lsusb
    Is it there? Also, do you need to install any other drivers for this device? Have you checked the Fujitsu site (* I just checked there and no Linux driver)?

    This might help. It's definitely supported.

    Re: Can't find scanner

    I think it is a USB scanner. When I tried:

    Code:
    lsusb
    I found:

    Code:
    Bus 002 Device 007: ID 04c5:10cf Fujitsu, Ltd
    I don't know much about drivers, but the Internet led me to this program called XSANE. I also tried Simple Scan and SANE-pygtk from the Software Center, and downloaded a program called VUE Scan, but none of them can find the scanner.

    I also tried following a tutorial

    https://help.ubuntu.com/community/SA...0auto-detected

    The instructions tell me to go to
    http://www.sane-project.org/sane-mfgs.html

    then enable the backend by

    Code:
    sudo gedit /etc/sane.d/dll.conf
    and changing

    Code:
    #example-backend
    to

    Code:
    #example-backend
    then

    Code:
    sane-find-scanner
    I did all that, but the instructions actually say "#example-backend" to #example-backend", so that's not clear to me. I assumed it meant for me to change "fujitsu" in the conf file to whatever the backend says at the sane-project website, but that says the Fujitsu fi-4340C's backend is "Fujitsu (117)". I tried changing the conf file every which way:

    fujitsu117
    fujitsu(117)
    fujitsu 117
    fujitsu (117)
    Fujitsu117
    Fujitsu(117)
    #fujitsu
    #fujitsu117
    #Fujitsu

    but nothing worked. That tutorial does not explain what to do if the scanner is not found after that, so I'm stuck there.

    Re: Can't find scanner

    You've done good research and good work there, puzzling the apps are not picking up the scanner because the machine knows it's there. I'll think a bit more when I've woken up some!

    Re: Can't find scanner

    scanimage -L
    that command will list all scanners
    this may be of use
    scanner-access-enabler-1.4.tar.bz2
    what does this command give you? groups $USER

    Re: Can't find scanner

    Code:
    scanimage -L
    returns

    Code:
    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).
    Code:
    groups $USER
    returns

    Code:
    jason : jason adm cdrom sudo dip plugdev lpadmin sambashare
    I downloaded the link, but I have no idea what to do with it. I'm new to Ubuntu and I only know how to install stuff through the software center.

    Re: Can't find scanner

    how about sudo scanimage -L

    this is odd, i cant access mine either but www-data can (just upgrade to saucy the other day from raring)
    if you install the scanner software linked in my signature you should be able to use the scanner that way
    I just turned the scanner on and could not access it
    ran sudo adduser $USER lp
    ran sudo service saned restart
    logged out
    login in and i have access to my scanner as the normal user

    +1. Nice tip. Let's see if that works ...

    Re: Can't find scanner

    I tried sudo scanimage -L again, and received the same message.

    Again, I am new to Ubuntu and I only know how to install from the Software Center; I could not install the stuff in your link.

    I tried sudo adduser $USER lp, and received: Done.

    Then I tried sudo service saned restart, and received: saned disabled; edit /etc/default/saned

    I'll try to log out, but I don't know what you need me to log out of. I guess I'll just log out of my computer?

    This doesn't sound like it's going to work, though.

    There is a Fujitsu conf file in /etc/sane.d. Am I suppossed to edit that?

    Re: Can't find scanner

    if scanimage -L with sudo did not see it it is not a permissions error as i suspected
    sane.d/ files should be for sharing the scanner i think
    maybe you need to modprobe something to get a driver working
