HP scanner not found

[Dave Welch]

I am having a scanner problem, I am trying to use my HP Scanjet 4470c on
a machine running Fedora 11 with sane 1.0.20-4.  I have followed all
that I understand in the documentation. I don't seem to have
libsane-rts8891.a on my system, do I need it? If so, where can I find
it?

When I used command  lsusb  see output below.
Bus 001 Device 005: ID 046d:c518 Logitech, Inc. MX610 Laser Cordless
Mouse
Bus 001 Device 002: ID 05e3:0608 Genesys Logic, Inc. USB-2.0 4-Port HUB
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 002: ID 046e:5503 Behavior Tech. Computer Corp.
Bus 002 Device 003: ID 03f0:0805 Hewlett-Packard HP4470C
Bus 002 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

When I start xsane it says no devises available.

This is the output of sane-find-scanner:
found USB scanner (vendor=0x03f0, product=0x0805, chip=rts8801/rts8891)
at libusb:002:004

When I used command  scanimage -L  see output below.

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).

When I used command  scanimage -d rts8891  the scanner scanned and
displayed garbage in the terminal.

Thanks for any help!

        Hello,

        scanimage output scanned data to the terminal. So the garbage you noticed was
binary data in pnm format. Try to test with redirecting standard output to a
file like:
scanimage -d rts8891 >scan.pnm 2>scan.log

        The libsane-rts8891.a file is only needed if you want to compile a frontend
statically which is rather uncommon. Usually, you only need 'libsane-
rts8891.so' file which is loaded dynamically by the SANE framework.

Regards,
        Stef

But, if you dont see the device with scanimage -L, but you do see it
with scanimage -d 'drivername' then probably your /etc/sane.d/dll.conf
does not have the backend listed in it, or it is commented out for
some reason?
