How can I get a CanoScan 8400F flatbed scanner working in Ubuntu?

I'd like to use a CanoScan 8400F scanner with my laptop, which is running Xubuntu 18.04. I can detect the scanner with both lsusb, which returns

Bus 002 Device 006: ID 04a9:221e Canon, Inc. CanoScan 8400F

and sudo sane-find-scanner, which returns

found USB scanner (vendor=0x04a9 [Canon], product=0x221e [CanoScan], chip=GL842) at libusb:002:006

However, neither scanimage nor SimpleScan will detect the scanner. I note that running sane-find-scanner without permissions also does not detect the scanner. A visit to the Sane supported devices page suggests that my scanner should be supported, though that's apparently as of Sane 1.0.31. I appear to be running Sane 1.0.27. I've run sudo apt-get update to no effect.

What am I missing? Is there any way to get this to work short of compiling the latest version of Sane myself? (Because I'm not going to do that. It's not worth the trouble.)

Thanks,

--John

I am using Ubuntu 21.04

Have you renamed ~/.sane to ~/.sane-bkup to clear away old settings?

For my own install, I had previously installed older versions of "backends" and had to remove them. ippusbxd is not installed, it has been replaced by ipp-usb whose current version is installed.

Have you cleaned up old attempts at getting this working? They will impact your results.

Have you ensured that in the /etc/sane.d/genesys.conf file has the line for the 8400F usb 0x04a9 0x221e uncommented.

My tests:

simple-scan automatically detects my Canon CanoScan 8400F.

xsane 0.999 automatically detects 8400F.

gscan2pdf automatically detects 8400F.

Disappointingly scangearmp2 does not detect scanner. I liked the "auto-crop" features when scanning multiple photos. Shame it cannot use the code present in tested options 1-3. Contained in /lib/bjlib are two files canon_mp2.conf and cifmx530.conf which may limit detected scanners.

skanlite installed from a snap also disappointingly did not detect scanner. This is because the /snap/skanlite/current/etc/sane.d/genesys.conf is out-of-date.

skanlite installed from apt-get install automatically detects 8400F.

When the 8400F is powered up and turned ON
find-sane-scanner generates:
found USB scanner (vendor=0x04a9 [Canon], product=0x221e [CanoScan], chip=GL842) at libusb:002:009 similar to yours.

scanimage -L returns genesys:libusb:002:009 which shows it does detect scanner
scanimage --device-name 'genesys:libusb:002:009' --format=jpeg > me.jpeg generates a gray scaled image. I haven't played with option settings as I prefer simple-scan, gscan2pdf, and xsane

I also have a Canon MX530 series network multi-function scanner, printer, fax and that is detected by options 1-3.
