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

[Marco Herrn]

Hi,

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:192.168.1.50' is a Hewlett-Packard HP LaserJet 3052 
multi-function peripheral


But when I want to scan, it says:


 $ scanimage --device=hpoj:hpjd:192.168.1.50 
 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?

Regards
Marco

 hpoj seems to no longer be supported by its makers. you could upgrade to 
 HPLIP? http://hplip.sourceforge.net/

Thanks, calling hp-makeuri 192.168.1.50 now gives me the URI
hpaio:/net/HP_LaserJet_3052?p=192.168.1.50. Giving to scanimage as device
does work and I get a correct scan.

However, scanimage -L does not list it as a device. Also xsane and
xscanimage obviously try to scan from the bttv TV-Card and provides 
me with no possibility to select the device. How can I register this
device to sane? (I am using Debian, if that helps.)
