Dear Sir/Madam,
I am trying to scan images through the scanner mentioned above. The
sane-find-scanner lists my scanner. Also scanimage -L lists the device
properly. But when I issue command scanimage image.pnm, I am getting
following errors and the hardware makes little motor noise and stops.
[genesys] WARNING: Your scanner is not fully supported or at least
[genesys] had only limited testing. Please be careful and
[genesys] report any failure/success to
[genesys] sane-devel@lists.alioth.debian.org. Please provide as
many [genesys] details as possible, e.g. the exact name of your
[genesys] scanner and what does (not) work.
Please let me know how to overcome this problems.
It would be a great help.
Thanks Regards,
Shailesh

Hello,
I'm back from a 2 weeks holidays. The support for HP2400 isn't
progressing
fast since I don't have access to such model. However, I'm in the process to
document how to add support for it, and doing some modifications to the
genesys backend. Current CVS version has support for the 2400C in warm up.
Tests and code finalization is left to people having a device to work on, and
willing to do it.
With the latest version of the documentation and code (at
http://perso.modulonet.fr/~stefdev/sane/gl646-wip03.odt), there should be
enough information to get warming up working. The 2 functions to test and fix
are:
- gl646_init_regs_for_warmup
- genesys_warmup_lamp
The set up of the scanner in the backend log will have to match this
