sane: scanimage refuses to use hp sj 2300c

Simon Bridge · 09-30-2005, 05:09 PM

In FC4:

I discovered that my hp scanjet 2300c now has a sane back end (genesys) which claims full support. Since scanning is the only thing I use windows for (rather than buy a new scanner) I was quite excited.

I got the latest sane-backends-1.0.16.tar.gz off www.sane-project.org, followed the instructions to install. No errors.

./configure
make uninstall
make
make install

(I know make uninstall dosn't remove all the previous install - bear with me)

sane-find-scanner correctly locates and identifies the scanner.
(Initially it would only do so when run as root, but it works fine as user after running the hotplug script.)

However - scanimage -L does not see any scanner at all!

The man pages point out that scanimage -L produces an incomplete list, and only for scanners whose backend has a conf file. Well genesys.conf is right there and correctly lists my scanner as supported.

I've read through, and followed, the man pages for sane, sane-usb, and sane-genesys.
I've been through the sane-project faqs and documentation.

The old install of sane (backends 1.0.15) in FC4 sticks some files in /etc/sane.d whereas the new one sticks everything in /usr/local/etc/sane.d ... thus make uninstall, while removing a great deal, did not remove the /etc set. I have yet to check what effect removing /etc/sane.d would do - fedora may expect sane there?

Which is part of the issue here - I had a go trying to get yum to update the sane packages ... but cannot find any. I figured that yum update xsane would do the trick... nope. Of course, the latest sane backends may just not be in the yum repos yet?

Here's some actual output:

Code:

[~]$ ls /dev/scan*
/dev/scanner-usb-:proc:bus:usb:003:002

[~]$ sane-find-scanner

found USB scanner (vendor=0x03f0 [Hewlett-Packard], product=0x0901 [hp scanjet scanner], chip=GL646_HP) at libusb:003:002
  # Your USB scanner was (probably) detected. It may or may not be supported by
  # SANE. Try scanimage -L and read the backend's manpage.

[~]$ scanimage -L

No scanners were identified. If you were expecting something different,
check that the scanner is plugged in, turned on and detected by the
sane-find-scanner tool (if appropriate). Please read the documentation
which came with this software (README, FAQ, manpages).

[~]$ scanimage -d genesys:/dev/scanner-usb-:proc:bus:usb:003:002 > image.png
scanimage: open of device genesys:/dev/scanner-usb-:proc:bus:usb:003:002 failed: Invalid argument

Note: this is not a permissions issue as scanimage behaves the same as root - besides, /proc/bus/usb/003/002 has owner "me" with rwx for everyone.

Hey Simon Bridge:
Sorry to be the bearer of sad news. I tried unsuccessfully for a number of months to get this scanner working under both Mandrake 10.0
and Ubuntu 5.04.
Final conclusion was that this model is not supported under sane, despite claims to the contrary on various lists and sources.
However, a couple of months back, I purchased the model BELOW this one (numerically) which is HP ScanJet 2200c and voila! Totally 100%
supported and works like a charm. It was immediately detected by SANE and Ubuntu, and has been absolutely trouble free.).

Hope this helps. I know how frustrating it is to have hardware that you've paid good money for, only to find out that it is not supported
under Linux.

Yes - I understand this.
My information about this scanner being supported comes direct from the backend developer and www.sane-project.org ... however, much more along this line and I will be winging to the same.

paperboy: update your information!

The hp sj2300c is now going.
It seems all I had to do was power down, then back up again.
Scans nicely and fast too.

Now - same scanner in ubuntu... see ubuntu forum.
