[sane-devel] HP5590 problems

[Paul Schenkeveld]

Hi,

I hope this is the right place to post this question, otherwise please
point me to a better place and accept my apologies for bothering you.

I'm trying to use a HP5590 scanner with sane-backends (1.0.21) running
on FreeBSD 8.2-PRERELEASE (tried 8.1-RELEASE with the same results).

I finally got the scanner to function more or less reliably by using
saned instead of talking to the scanner directly.  Only the ADF is not
working.  When I execute:

    scanimage -x 210 -y 297 --source ADF > scan.out

the scanner moves the lamp towards the left where the ADF aperture is
located, it then pulls one sheet from the ADF as if it were scanning
but scanimage displays:

    scanimage: sane_start: Invalid argument

and exits leaving scan.out empty.

Setting SANE_DEBUG_HP5590 to 50 reveals the folowing debugging lines:

    [sanei_debug] Setting debug level of hp5590 to 50.
    [hp5590] SANE backed for HP ScanJet 4500C/4570C/5500C/5550C/5590/7650 1.0.5

    [hp5590] sane_hp5590_get_devices, local only: 0
    [hp5590] Found 0 devices
    scanimage: sane_start: Invalid argument
    [hp5590] sane_hp5590_exit

Any ideas?

Thanks in advance,
