    Re: simple scan does not find scanner

    I had this error not long ago when resurrecting an Acer scanner which was last used with Windows XP 15 years ago.
    The terminal can help by giving some feedback on the problem:

    Can sane see the scanner?
    Code:
    sane-find-scanner
    If not found, be sure scanner is on. Try again with sudo. Other suggestions I have seen are: try another USB port. Try another cable.
    Check to be sure scanner is supported: http://www.sane-project.org/sane-supported-devices.html
    If found (my Acer was found), try the command:
    Code:
    simple scan
    It may point to the problem, similar to this:
    Code:
    dmn@Sydney:~$ simple-scan
    [snapscan] download_firmware: No firmware entry found in config file snapscan.conf.
    Following that message, there were instructions on how to setup firmware. Firmware here means driver. For mine, not only was there no firmware entry in the config file, there was no driver. You need a specific driver for your scanner model. Find it online if you don't have it on some driver disk and copy it to the right location, then edit the config file probably in /etc/sane.d. Then it should work.

    Thanks. Commands tell me scanner is not detected. The SANE site tells me that whatever they have for my scanner is "untested". They need testers. I am not anxious to be a tester.

    If I find a solution I will post it.
