	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 
(extracted from usb logs):
slope_table0=7210 7210

 I downloaded daily CVS snapshot for sane-backends from
http://www.sane-project.org/snapshots/sane-
backends-2006-08-27.tar.gz
then i uninstalled previous 1.0.18 and installed this and
used command
scanimage -d genesys:libusb:003:010  > pp.pnm
2>linuxlogforcvs.log
when i saw that log file i got same warmup error. here are
last few
lines from my log

	Hello,

	what you miss is  to also set debug for gl646 code 
(SANE_DEBUG_GENESYS_GL646=255), then look in  debug log the
register set 
written to scanner at each scan during warm up. Then search
for differences 
with the values registers should have, fix/modify the 
gl646_init_regs_for_warmup() function until there are no -or
harmless- 
differences.

Regards,
	Stef
