I've had problems over the years getting my canon pixma mp490 scanner recognized. At first (Fedora 19) I installed the proprietary drivers (including scanner) for the mp490. That worked until I updated to Fedora 20. Then I installed gutenprint from the fedora repositories which enabled the computer to print and scan with the mp490. Recently I upgraded to Fedora 24 and, although the canon printer would still print, I could not get the mp490 scanner to be recognized. I reinstalled gutenprint, xsane, etc to no avail.

I then looked through the repositories for sane (after having googled extensively without finding a solution) and spotted "sane-backends" which I had never installed. After installing via dnf, my canon scanner was immediately recognized and was able to scan again.

This is how I found sane-backends (I realize that to many users this is quite obvious):


# dnf search sane

Here are the results (found near the bottom of the dnf print-out):


xsane.x86_64 : X Window System front-end for the SANE scanner interface
sane-backends-drivers-scanners.x86_64 : SANE backend drivers for scanners
sane-backends-drivers-scanners.i686 : SANE backend drivers for scanners
libsane-hpaio.x86_64 : SANE driver for scanners in HP's multi-function devices
libsane-hpaio.i686 : SANE driver for scanners in HP's multi-function devices

it's sharing of information rather than a question I believe. as such I'll modify the title to reflect it
