Hi,
Actually, I just saw the screenshot attachments and I notice that the
"apt upgrade" installed the new version of libsane which would have
included the updates.
Adding the repo and doing "apt update" just pulls down the repository
information, but does not perform any upgrade operations.
The "apt upgrade" does that, so that is probably what did the trick.
If you were running simple-scan while the upgrade was being performed,
you would not see the effect of the upgrade until you restarted
simple-scan, as it would have been holding on to the previous version of
the libsane backends.
Cheers,
Ralph

Hurrah! Gentlemen, you have saved my life. I'm not sure which of
these saved the day, but suddenly the scanner is showing two versions
of the printer, and the second version now scans.
Thank you so much.
All the best

Hi Ralph & Thierry & co
Thank you for getting back to me. I have run the following commands
as suggested:
apt update
apt install libsane libsane-common sane-utils
sudo apt upgrade
But I'm still getting exactly the same response from Simple Scanner
- it sees the printer, but when I attempt to scan is says scanner
not connected.
I'm at my wits end! Any more suggestions? I have multiple page
documents to scan.
OK, I have a few suggestions to see what is going on here.
Firstly, if this is a new scanner to you, I would check that the
scanner does not require you to select some mode on the device itself
to enable remote scanning.
I have a Canon multi-function machine here (imageClass MF4770n) and in
order to do scanning, I have to set it into "Remote Scanning" mode
using the control panel, otherwise, I get exactly the same error as
you, although the error is pretty generic.
Secondly, I assume that you are using the ADF at the moment. Could you
attempt a scan on the flatbed area and let us know if this works?
The reason I ask is that the pixma backend has problems with a number
of newer Pixma machines and this would at least determine that SANE is
talking the right language and getting through to the device
sufficiently to have a conversation. Also, while clunky and awkward
compared to the ADF, you might be able to get some work done.
Thirdly, perhaps you could type the following in a terminal window:
SANE_DEBUG_PIXMA=50 SANE_DEBUG_ESCL=50 SANE_DEBUG_DLL=10 simple-scan
pixma.out 2>&1
...and try to perform an ADF scan. This should generate some
informative information about the escl and pixma backends, the things
that are being loaded.
Then attach the pixma.out file that is generated to a reply here.
Hopefully, we can get you going.
Cheers,
Ralph
Did you choose the "single-source" in simple-scan ?
I noticed that it defaults to "All pages From Feeder"
