[sane-devel] "Error during device I/O" with ehternet attached HP LJ 3052

I have a HP Laserjet 3052 that is connected to my computer via ethernet.
Printing with the laserjet works fine. But scanning doesn't.

The printer is found when calling scanimage with parameter -L:

 $ scanimage -L
 device `v4l:/dev/video0' is a Noname BT878 video (Hauppauge (bt878)) virtual device
 device `hpoj:hpjd:' is a Hewlett-Packard HP LaserJet 3052 multi-function peripheral

But when I want to scan, it says:

 $ scanimage --device=hpoj:hpjd: 
 scanimage: sane_start: Error during device I/O

Now what can be the problem? I already put  "option dumb-read" to
/etc/sane.d/hp.conf, but it didn't help. I tried to get more output from 
scanimage by using -v and exported "SANE_DEBUG_HPOJ=255", but scanimage says
nothing more than the error message above. 
On each call of scanimage the ethernet port of the printer flashs, so obviously
the printer receives something.

So, what can I do to get near to the problem?
