[sane-devel] Canon MX530 - Error during device I/O

[Stephen Weston]

Dear all,

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.

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.

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.

Any help would be appreciated and I am willing to do any testing as

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.

Hi Stephen,

Please try my SANE Release PPA:
https://launchpad.net/~rolfbensch/+archive/ubuntu/sane-release .

If your scanner is working with this, please try my inofficial test ppa:
https://launchpad.net/~rolfbensch/+archive/ubuntu/sane-test .

Other users reported similar problems with their scanners. I suppose a
problem with one of the recent commits to the git repository.

Hope this helps.

Cheers,
Rolf

Hi Stephen,

I would like to know which build fails. Please test the recent version
from my test ppa.

The problem is that on my system I cannot reproduce the problem with
your scanner.

Many thanks for your help in advance.

Cheers,
Rolf

Rolf,
Thanks for your help. The scanner appears to work with the SANE release
PPA and your test PPA. Terminal output below:-

However, a relatively less serious issue, if I leave the scanner for a
more extended period of time (for it to go into standby), when I attempt
use it I get the following output. It appears that SANE is unable to
wake the scanner up out of standby.
scanimage: scanning image of size 638x877 pixels at 24 bits/pixel
scanimage: acquiring RGB frame, 8 bits/sample
scanimage: reading one scanline, 1914 bytes... [bjnp]
bjnp_open_tcp: ERROR - Can not connect to scanner: Connection refused
FAIL Error: Invalid argument
After pressing a button on the device to wake it up out of standby it
works fine again. Not a serious issue as pressing a button on the
scanner to wake it up isn't too problematic.
Kind regards,
Stephen
