Hello
I have a multifunction canon pixma mx 495. Up
to 1.0.25+git20150528-1ubuntu2, I only had one small issue, the ADF wasnt
working, but flatbed was ok.

Since 1.0.27+git20170719-xenial0, in flatbed mode, I can only scan on page
and then I get an error:
scanimage: sane_read: Error during device I/O

after scaning one page, trying to scan a second.

Reverting to 1.0.25 restore the previous way of working and allows me to
scan multiple pages via flatbed.

scanimage -L gives:
device `pixma:04A91787' is a CANON Canon PIXMA MX490 Series multi-function
peripheral

I've tried 1.0.27 with /etc/sane.d/pixma.conf from 1.0.25, but
unfortunately, that does not work.

As an FYI, the ADF reports 'Operation was cancelled' in 1.0.25 and .27

Thanks for any help to have this scanner keep on working,

Rgds

Rolf is the guy you want to talk to. I think he is England time zone. I
usually don't here back from him until around 3am at my time and I'm
Pacific Time.
Just be patient.

Hi Jean,

Please try my other ppa's (SANE Release and SANE Test) with older
versions of SANE: https://launchpad.net/~rolfbensch and report the
results. Then I'll have an idea where to search for the issue you reported.

Please be patient. I'm on the move until end of August and I have less
time to work on SANE.

Hope this helps.

Cheers,
Rolf

Hi Rolf,

First, thank you for looking into this.
Second, there is no rush, as I have a workaround reverting to 1.0.25,


I've tried with sane-release ppa,
scanimage (sane-backends) 1.0.27git; backend version 1.0.27
and it works fine

same with sane-test, which is ok,

I've reverted to sane-git, and it fails again.

Let me know if you need more info,

J.
