I just installed C7 on a new computer and despite Simple Scan being installed as part of C7, I have not been able to get it to recognize my Canon scanner connected to a USB port. I did have it running on another computer with C7 so there should not be any inherent issues.
On a lark I installed gscan2pdf and sane-backends-drivers-scanners and sane-find-scanner found it:
found USB scanner (vendor=0x04a9 [Canon], product=0x1908 [CanoScan]) at libusb:001:010
I perused my notes for the old computer but did not see I installed any additional software to get it going but I might be wrong.
What have I missed?
Thank you.

On my C7 box, simple-scan requires libsane. try: ldd simple-scan |grep -i sane.
# ldd /usr/bin/simple-scan | grep -i sane libsane.so.1 => /lib64/libsane.so.1 (0x00007f3668291000)
ldd doesn't show any other sane dependencies, but I'd sorta think that simple-scan would also need sane-backends as well. Here's all the sane things I have installed, FYI:
# ldd /usr/bin/simple-scan | grep -i sane libsane.so.1 => /lib64/libsane.so.1 (0x00007f3668291000) [root@fcshome log]# yum list installed | grep -i sane libsane-hpaio.x86_64 3.15.9-5.el7 @base sane-backends.x86_64 1.0.24-12.el7 @base sane-backends-devel.i686 1.0.24-12.el7 @base sane-backends-devel.x86_64 1.0.24-12.el7 @base sane-backends-doc.noarch 1.0.24-12.el7 @base sane-backends-drivers-cameras.i686 1.0.24-12.el7 @base sane-backends-drivers-cameras.x86_64 1.0.24-12.el7 @base sane-backends-drivers-scanners.i686 1.0.24-12.el7 @base sane-backends-drivers-scanners.x86_64 1.0.24-12.el7 @base sane-backends-libs.i686 1.0.24-12.el7 @base sane-backends-libs.x86_64 1.0.24-12.el7 @base sane-frontends.x86_64 1.0.14-19.el7 @base xsane.x86_64 0.999-9.el7 @base xsane-common.x86_64 0.999-9.el7 @base xsane-gimp.x86_64 0.999-9.el7 @base
also FYI, I'm using a Canon LiDE 210, which works fine for me.
Good luck!

Problem solved, I had forgotten to launch the saned daemon... Scanning now works.

So this is a CanoScan 9000. According to http://sane-project.org/sane-mfgs.html#Z-CANON it is supported since sane-1.0.27. Centos 78 apparently has Sane 1.0.24. So you must have downloaded a later version of Sane somewhere or compiled it yourself (not too difficult)

Hmm, I have no recollection of compiling sane. Btw, it is not clear to me where you saw that version 1.0.27 is needed? This scanner seems to be fully supported in the sane-pixma library.
