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
