Hi all,
=20
I compiled the newest SANE Version on my linux box where a Fujitsu
M3091DC scanner is cable-connected.
=20
Scanimage works basically but the option "-duplex both" doesn't work and
"-mode Halftone" generates an "invalid argument" error. "-mode Lineart"
only generates inverse images (white characters on black paper).
=20
Scanning with "-mode Color" or "-mode Gray" works in "nonduplex", but
they generate bigger images despite a lower resolution than Lineart.
=20
Do you have a suggestion how to scan in duplex and halftone or lineart?
=20
Here are some scanimage outputs:
=20
scanimage -L
=20
device `fujitsu:/dev/sg0' is a FUJITSU M3091DCd scanner
=20
=20
scanimage --help --device fujitsu:/dev/sg0
=20
Options specific to device `fujitsu:/dev/sg0':
Scan Mode:
--source ADF|FB [ADF]
Selects the scan source (such as a document-feeder).
--mode Lineart|Halftone|Gray|Color [Color]
Selects the scan mode (e.g., lineart,monochrome, or color).
--duplex front|both [front]
Select if you want the front or back to be scanned, or both.
--resolution 50..300dpi (in steps of 1) [300]
Sets the horizontal resolution of the scanned image.
--y-resolution 75|150|300|600dpi [300]
Sets the vertical resolution of the scanned image.

Thanks
