Could you do the following and post the output...

$ export SANE_DEBUG_DLL=128
$ scanimage -L

Thanks

jh

Aaron,

Thanks for your reply. I've posted the lines.

Try running:

snmpwalk -Os -c public -v 1 ip.address.of.printer 1.3.6.1.4.1.11.2.3.9.1.1.7.0

where ip address of printer is the IP address of the printer.

Is it possible to connect the printer locally and test the scanning via usb?

A

Sorry about delay - I've been away for a few days.

Found a USB cable and connected it. Xsane presented two options, network and USB. Selected USB and it scanned OK. Then selected the network option and that also scanned! Just to be sure it wasn't still using the USB I disconnected that and scanned by the network again.

The 6.06 box had had its OS rebuilt in the meantime so I downloaded and installed the latest hplip 2.8.7 and that also scans through the network.

So --- either the USB connection has nudged the scanner out of some stuck state or some routine update to Ubuntu in the interim has replaced a faulty library.

Whatever the explanation it seems OK now. Thanks for your help.

Ian

I am having a very similar problem with an HP 3030 all-in-one product -- the same error messages in /var/log and everything.

I have opened a support question here:

https://answers.launchpad.net/hplip/+question/61180

Mine has not magically solved itself!

I would appreciate any suggestions you might have.

Thanks.

Sarah,

I took the scanner off the network, powered it all down, connected via
USB and powered up. It worked OK so I disconnected USB & put it back on
the jet direct box again and it still worked. I suspect that my scanner
and/or jetdirect box had got itself into some odd state causing it not
to work with HPLIP.

I have the JD box set up to a fixed IP address BTW, not assigned through
DHCP.

Thanks.

Unfortunately, I tried that after reading your original experience (except for the USB connection), and it didn't work.

You also mentioned above that your distro went through a software change between the bugginess and the fix. As a result, I installed the debian experimental version of the hplip package, which at 2.8.12 is newer than the 2.8.7 that may have fixed your problem. Alas, this also failed.

Connecting by USB is not an option for me, as the scanner is in a different room from the computer and this cannot change for other reasons.

Thanks again for your quick response and helpful suggestion, though!

FWIW I'm running hplip 2.8.6b, installed from the HP site rather than
the version on the Ubuntu archives, under Ubuntu 8.04.

It's very difficult to understand exactly what has & hasn't fixed a
problem in such circumstances.

The USB connection was only tried out as a very unsatisfactory possible
alternative. I mostly work from a laptop but mostly, like yourself, in
a different room. It just so happened that I have beside the printer
the oddest setup you'll have seen for some time - a Neoware thin client
with its internal solid-state disk removed and an old laptop disk
attached in a USB housing, also running Ubuntu but currently 6.06. I'm
not sure what version hplip that has. I'll check & let you know.

I checked the other box. It's on 2.8.7 and also scans OK on the network.

Ian -- thank you so much for the follow-up. To summarize, you have two ubuntu boxes, one running hplip 2.8.7 and one running 2.8.6b, both of which work with a 3020. I have one debian box running 2.8.6b, that does not work with a 3030.

The 3020 and the 3030 are very similar, and ubuntu and debian are also quite similar, so I don't know how much any of this helps. I think the deciding question is going to be whether the HP guys can make anything of the /var/log messages. Yours were:

Jul 31 23:51:36 hazel xsane: io/hpmud/jd.c 353: invalid scan response 1 port 9290 hp:/net/hp_LaserJet_3020?ip=172.16.0.4
Jul 31 23:51:36 hazel xsane: failed to open scan channel: scan/sane/pml.c 631

And mine are:

Feb 15 20:27:35 system kooka: io/hpmud/jd.c 353: invalid scan response 1 port 9290 hp:/net/hp_LaserJet_3030?ip=10.10.10.32
Feb 15 20:27:35 system kooka: failed to open scan channel: scan/sane/pml.c 631

I dare say that's pretty likely the same problem!

If anyone else has this problem, I encourage you to post on my open question:

Since Ian's problem has gone away and his question is marked solved, if there is any response from HP it will be in my question.

Ian, thanks again!
