Hello SANE people,
I have a Fujitsu fi-5110eox ADF scanner that I use on Ubuntu 8.04 with
scanimage and the fujitsu backend (both version 1.0.19). A couple of
questions:
1.
The 5110 has a couple of paper guides that are adjusted symmetrically,
so that the paper is centered with respect to the scanner's vertical
center axis. According to the sane-fujitsu man page the pagewidth option
is used by the scanner to determine centering of scan coordinates.
Am I correct in assuming that as long as you correctly set the pagewidth
option, (tl-x, tl-y) = (0, 0) is always at the top left corner of the
inserted sheet? Because that is not what I get, as seen from the
attached example of scanning an A5 page:
scanimage --pagewidth=148 --pageheight=210 -t 0 -l 0 -x 148 -y 210
--resolution=150 --source='ADF Front' > out.pnm
It looks as if the horisontal reference is at the extreme left of the
scanning area. Is this a bug? If not, what is the purpose of the
pagewidth option?
2.
According to scanimage --help, the scanner accepts a --pageheight of up
to 863.489 mm. Then why is the max value for -t and -y reported to be
only 279.364 mm? (This value corresponds to 'letter' format?)
Thank you in advance.
Best regards,
Jacob Nielsen

$ scanimage -V
scanimage (sane-backends) 1.0.19; backend version 1.0.19
$ scanimage -L
device `fujitsu:libusb:006:005' is a FUJITSU fi-5110EOX scanner
$ scanimage --help -d fujitsu:libusb:006:005
Usage: scanimage [OPTION]...
Start image acquisition on a scanner device and write PNM 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), and %i (index number)
-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 number in filename by an amount of #
--batch-double increment page number by two for 2sided originals
being scanned in a single sided scanner
--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
-h, --help display this help message and exit
-v, --verbose give even more status messages
-B, --buffer-size change default input buffersize
-V, --version print version information
Options specific to device `fujitsu:libusb:006:005':
Scan Mode:
--source ADF Front|ADF Back|ADF Duplex [ADF Front]
Selects the scan source (such as a document-feeder).
--mode Gray|Color [Gray]
Selects the scan mode (e.g., lineart, monochrome, or color).
--resolution 100..600dpi (in steps of 1) [600]
Sets the horizontal resolution of the scanned image.
--y-resolution 50..600dpi (in steps of 1) [600]
Sets the vertical 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.
--pagewidth 0..224.846mm (in steps of 0.0211639) [215.872]
Must be set properly to align scanning window
--pageheight 0..863.489mm (in steps of 0.0211639) [279.364]
Must be set properly to eject pages
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.
--rif[=(yes|no)] [no]
Reverse image format
Advanced:
--dfdetect Default|None|Thickness|Length|Both [Default]
Enable double feed sensors
--dfdiff Default|10mm|15mm|20mm [Default]
Difference in page length to trigger double feed sensor
--dropoutcolor Default|Red|Green|Blue [Default]
One-pass scanners use only one color during gray or binary scanning,
useful for colored paper or ink
--overscan Default|Off|On [Default]
Collect a few mm of background on top side of scan, before paper
enters ADF, and increase maximum scan area beyond paper size, to allow
collection on remaining sides. May conflict with bgcolor option
--sleeptimer 0..60 (in steps of 1) [0]
Time in minutes until the internal power supply switches to sleep mode
