Hi Troels,<br>
<br>
Many thanks for your report.<br>
<br>
Please test with xsane instead of scanimage and check if the scanner
"hangs" with xsane too.<br>
<br>
If so, please create a log file on a terminal with 'export
SANE_DEBUG_PIXMA=11' and 'xsane &> pixma.log'. And please
create an USB log file on a Windows machine e.g. with usblyser and
export the protocol as html file. <br>
<br>
The mailing list will reject your response with a big file attached.
Please send it direct to my email address.<br>
<br>
Cheers,<br>
Rolf<br>

-patch and scanner really works!<br>
<br>
I'm pulling code from git, and have followed the install
guide, and am observing the following:<br>
<br>
</div>
- Scan --mode=grey/color works<br>
</div>
<div><br>
- Scan --resolution=600 works (and 75)<br>
</div>
<br>
- Buttons ... could not make it work<br>
<br>
- "scanimage -x 55 -y 55" works but "scanimage -x auto -y
auto" does not<br>
</div>
<br>
- after scanning completes, the scanner is still printing
"scanning ..." in the display, and can not print another page
until it is forced out of this state (red 'clear' button, -
are you sure? - yes)<br>
<br>
</div>
<div>- There is a pause of 10 seconds before everything. It
must have something to do with the backend, because it is even
there when doing <br>
<span style="font-family:courier new,monospace">scanimage
--help</span><br>
The first page of options is printed immediately, then the 10
sec pause, then the rest is printed, starting with:<br>
<span style="font-family:courier new,monospace">Options
specific to device `pixma:04A92779_2c9efc4f5de2':</span><br>
<br>

I'm running linux mint 16. Connection is USB at the moment.<br>

<div bgcolor="#FFFFFF" text="#000000"> Hi Troels,<br>
<br>
I prepared a quick patch for your scanner in
'backend/pixma_imageclass.c'. The patch is based on recent
development version 1.0.25.<br>
<br>
You also need to copy the attached udev rules file to
'/etc/udev/rules.d'.<br>
<br>
I also added MF8500C Series. Both scanners should work
with this patch, if they are similar to running MF4700
Series.<br>
<br>
Please read README.linux for installing Sane and basic
testing. <br>
<br>
If you want to see some debug messages in a terminal or if
you want to use ethernet, please read sane-pixma man page.<br>
<br>
Cheers,<br>
Rolf<br>
