</div><div>As seen below, its not the pixma enumeration that takes all this time (only one second), so I'm suspecting it's because all the backends are given a chance to find a device. And given the number of backends this will obviously take some time.<br>

<div><br></div><div>scanimage -d mfnp://mf8230:8610<br></div><div>does not work, <br>- can I specify a network device on the command line like this?<br></div><div>- and will that stop the auto-detection?<br></div><br></div>

Hi Troels<br>
pixma.conf should have only contain<br>
mfnp://<a href="http://192.168.1.50:8610" target="_blank">192.168.1.50:8610</a><br>
in your case. It tells the backend where to find the scanner. The mfnp<br>
part tells the backend that the device is a laser multi-functional (I<br>
still don't understand why Canon choose to make that a different<br>
protocol as except for the protocol name, identifier an port it is<br>
pretty much the same as the bjnp protocol.<br>
The delays may come from the reverse lookup on 192.168.1.50.<br>
What does<br>
nslookup 192.168.1.50<br>
return? Hoe long does that take? I guess around 5 seconds?<br>
<br>
What is the content of /etc/resolv.conf on your machine? Which<br>
namservers do you use? Do you run your own nameserver?<br>
<br>
kind regards, Louis<br>
