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
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)
