Hello, Thanks for your answer. I've downloaded the git version. It compiled fine out of the box although I got a warning in the configure phase: checking IOKit/scsi/SCSITaskLib.h usability... no checking IOKit/scsi/SCSITaskLib.h presence... yes configure: WARNING: IOKit/scsi/SCSITaskLib.h: present but cannot be compiled configure: WARNING: IOKit/scsi/SCSITaskLib.h: check for missing prerequisite headers? configure: WARNING: IOKit/scsi/SCSITaskLib.h: see the Autoconf documentation configure: WARNING: IOKit/scsi/SCSITaskLib.h: section "Present But Cannot Be Compiled" configure: WARNING: IOKit/scsi/SCSITaskLib.h: proceeding with the preprocessor's result configure: WARNING: IOKit/scsi/SCSITaskLib.h: in the future, the compiler will take precedence configure: WARNING: ## ------------------------------------------------- ## configure: WARNING: ## Report this to sane-devel at lists.alioth.debian.org ## configure: WARNING: ## ------------------------------------------------- ## Now, indeed, grayscale scanning works fine from command line. % scanimage -V scanimage (sane-backends) 1.0.22git; backend version 1.0.22 % scanimage -L device `genesys:libusb:002:002-03f0-0a01-ff-ff' is a Hewlett Packard ScanJet 2400c flatbed scanner % scanimage --verbose --progress --resolution 300 --mode Gray >image2.pnm [genesys] WARNING: Your scanner is not fully supported or at least [genesys] had only limited testing.
