Scanner Tool can't find scanner

I recently had to re-install FC 6 when I applied updates and after the updates my Nvidia kernel was overwritten and I couldn't get into the Gnome GUI. After the re-install the Scanner Tool couldn't find the scanner of my HP 7300 All-In-One USB printer setup. It worked before the re-install and before the Nvidia kernel build.

On the re-install I opted to install both the KDE and the Gnome GUI's. Before I only did the Gnome. That's the only thing I can think of that I did differently.

I tried the FC9 upgrade and it was all good but the Scanner Tool (shane) still can't find the scanner.

I need to find out how to help the Scanner Tool find the scanner.

Im using FC9 with an Intel Duel Core 64 with 2 GB Ram and a 160 GB 7200 RPM SATA.

Re: Scanner Tool can't find scanner

Shalom,

I can't see the nvidia kernel as the source of this problem. Still, I would like to see a procedure and software.

I tend to see a cabling or hardware problem as the cause of this.

Is the scanner visible to a live cd distro from another Linux?

Perhaps you need different drivers form the Scanner manufacturer. Any clues in /var/log/messages?

Re: Scanner Tool can't find scanner

Hi Steven; all my other software sees the printer portion of the HP 7300 and the scanner copies and prints Ok. Also the USB hookup wasn't changed during the installation.

Since the FC9 upgrade the Nvidia kernel build fails at the point where it tries to replace the old kernel. However, I've always been able to use the Scanner Tool even without the Nvidia driver compiled into the kernel.

Re: Scanner Tool can't find scanner

I think this is related to your locale after the upgrade.

Open up a shell as root, and then change the LANG variable to en_US like this:

# export LANG=en_US


Next, run hp-setup.
Then, run scan-find-scanner and see if your scanner is recognizable.

Good luck!

Re: Scanner Tool can't find scanner

I did as you reccommended; hp-setup found the scanner and did its thing; sane-find-scanner found the scanner; scanner tool scans for devices and reports "no devices available'.

It seems everything knows about the scanner but the scanner tool.

Re: Scanner Tool can't find scanner

Let go with this:

1) export LANG=POSIX
2) export LC_ALL=POSIX
3) hp-setup
4) /etc/init.d/hplip restart
5) sane-find-scanner
