I all,
i have a problem with a CANON DR-3060 SCSI scanner.
scanimage -L is ok but when i want start the scan with command line
root at debian:~/dev/sane-backends-git20130912# scanimage
--batch="tmp/test%d.pnm" --batch-start=1 --source "ADF Front"
Scanning -1 pages, incrementing by 1, numbering from 1
Scanning page 1
scanimage: sane_start: Invalid argument
root at debian:~/dev/sane-backends-git20130912# scanimage -L
device `canon_dr:/dev/sg2' is a CANON DR-3060 scanner
scanimage -h :
------------------------------------------------------------------------------------------------------------------
root at debian:~/dev/sane-backends-git20130912# scanimage -h
Usage: scanimage [OPTION]...
Start image acquisition on a scanner device and write image data to
standard output.
Parameters are separated by a blank from single-character options (e.g.
-d epson) and by a "=" from multi-character options (e.g.
--device-name=epson).
-d, --device-name=DEVICE use a given scanner device (e.g. hp:/dev/scanner)
--format=pnm|tiff file format of output file
-i, --icc-profile=PROFILE include this ICC profile into TIFF file
-L, --list-devices show available scanner devices
-f, --formatted-device-list=FORMAT similar to -L, but the FORMAT of the
output
can be specified: %d (device name), %v (vendor),
%m (model), %t (type), %i (index number), and
%n (newline)
-b, --batch[=FORMAT] working in batch mode, FORMAT is `out%d.pnm' or
`out%d.tif' by default depending on --format
--batch-start=# page number to start naming files with
--batch-count=# how many pages to scan in batch mode
--batch-increment=# increase page number in filename by #
--batch-double increment page number by two, same as
--batch-increment=2
--batch-prompt ask for pressing a key before scanning a page
--accept-md5-only only accept authorization requests using md5
-p, --progress print progress messages
-n, --dont-scan only set options, don't actually scan
-T, --test test backend thoroughly
-A, --all-options list all available backend options
-h, --help display this help message and exit
-v, --verbose give even more status messages
-B, --buffer-size=# change input buffer size (in kB, default 32)
-V, --version print version information
Options specific to device `canon_dr:/dev/sg2':
Standard:
--source ADF Front|ADF Duplex [ADF Front]
Selects the scan source (such as a document-feeder).
--mode Lineart|Gray [Gray]
Selects the scan mode (e.g., lineart, monochrome, or color).
--resolution 200|240|300dpi [300]
Sets the resolution of the scanned image.
Geometry:
-l 0..215.872mm (in steps of 0.0211639) [0]
Top-left x position of scan area.
-t 0..279.364mm (in steps of 0.0211639) [0]
Top-left y position of scan area.
-x 0..215.872mm (in steps of 0.0211639) [215.872]
Width of scan-area.
-y 0..279.364mm (in steps of 0.0211639) [279.364]
Height of scan-area.
--page-width 0..255.999mm (in steps of 0.0211639) [215.872]
Specifies the width of the media. Required for automatic centering
of
sheet-fed scans.
--page-height 0..364.02mm (in steps of 0.0211639) [279.364]
Specifies the height of the media.
Enhancement:
--brightness -127..127 (in steps of 1) [0]
Controls the brightness of the acquired image.
--contrast -127..127 (in steps of 1) [0]
Controls the contrast of the acquired image.
--threshold 0..255 (in steps of 1) [inactive]
Select minimum-brightness to get a white point
Advanced:
--df-thickness[=(yes|no)] [no]
Detect double feeds using thickness sensor
--df-length[=(yes|no)] [no]
Detect double feeds by comparing document lengths
--rollerdeskew[=(yes|no)] [no]
Request scanner to correct skewed pages mechanically
--swdeskew[=(yes|no)] [no]
Request driver to rotate skewed pages digitally
--swdespeck 0..9 (in steps of 1) [0]
Maximum diameter of lone dots to remove from scan
--swcrop[=(yes|no)] [no]
Request driver to remove border from pages digitally
--stapledetect[=(yes|no)] [no]
Request scanner to halt if stapled pages are detected
--dropout-front None|Red|Green|Blue|Enhance Red|Enhance Green|Enhance
Blue [None]
One-pass scanners use only one color during gray or binary scanning,
useful for colored paper or ink
--dropout-back None|Red|Green|Blue|Enhance Red|Enhance Green|Enhance
Blue [None]
One-pass scanners use only one color during gray or binary scanning,
useful for colored paper or ink
--buffermode[=(yes|no)] [no]
Request scanner to read pages async into internal memory
Sensors:
Type ``scanimage --help -d DEVICE'' to get list of all options for DEVICE.
