<p>Hi Stephen,</p>
<p>Please try my SANE Release PPA:
<a class="moz-txt-link-freetext" href="https://launchpad.net/~rolfbensch/+archive/ubuntu/sane-release">https://launchpad.net/~rolfbensch/+archive/ubuntu/sane-release</a> .<br>
</p>
<p>If your scanner is working with this, please try my inofficial
test ppa:
<a class="moz-txt-link-freetext" href="https://launchpad.net/~rolfbensch/+archive/ubuntu/sane-test">https://launchpad.net/~rolfbensch/+archive/ubuntu/sane-test</a> .</p>
<p>Other users reported similar problems with their scanners. I
suppose a problem with one of the recent commits to the git
repository.</p>
<p>Hope this helps.</p>
<p>Cheers,<br>
Rolf<br>

<div>Dear all,<br>
<br>
</div>
I am hoping to get some help to get the scanner on my Canon
MX535 multi-function device working. In the past it has
worked no problems, but trying it recently it has not been
so successful. The printer function works perfectly. I am
using Ubuntu Gnome 17.04 fully updated and with the sane-git
repository. I am using the scanner over wifi.<br>
<br>
</div>
After testing the scanner as much as I know how it appears
that the scanner works initially, but then fails after trying
to use it a second time. So, on the standard work flow in
xsane of doing a preview first, then selecting the scan area
and clicking scan, the scanner will do the preview fine, but
fail with 'Error during device I/O" on clicking scan. After
the initial scan appears to have completed the scanner is left
in a 'busy' state with 'Scanning...' displayed on its screen
and a blue LED flashing as if its still trying to work away
(although the light bar looks parked and is not lit up).
Switching the scanner off and on again allows me to scan
again, but only once before the same happens.<br>
<br>
</div>
I include the output from using scanimage to test the device
below. I have run scanimage -T twice, the second time shortly
after the first 'successful' attempt.<br>

<div>P.S. sorry, this is my second post on to this mailing list.
Not sure if my first email got through or not, but
unfortunately I did not get a reply. I'm hoping with this
extra information someone may be able to help.<br>
