LinLin schriebHardwaredefekt ausgeschlossen: in Windows 7 geht er einwandfrei. Wenn ich in Arch gescannt hab und dann zu Win7 geh, dann kallibriert er ewig lang rum.
Sollte der Scanner vorher nicht auch noch eine Kallibrierung bei Arch machen.

Dein Scanner wird mit diesen Treiber benutzt. Scheinbar geht das kalibrieren nicht automatisch sondern es muss per Option gestartet werden.
Auszug daraus:
CALIBRATION
To give correct image quality, sheet fed scanners need to be calibrated
using the calibration sheet sold with the scanner. To do calibration,
you must insert this target in the feeder then start calibration either
by passing the --calibrate option to scanimage or by clicking on the
available 'calibrate' button in the 'advanced options' in a graphical
frontend. The result of the calibration is stored in a file in the home
directory of the user doing it. If you plug the scanner in another
machine or use it with another account, calibration will have to be
redone, unless you use the --calibration-file option. If no home
directory is defined, USERAPPPROFILE will be used, then TMPDIR or TMP.
If none of these directories exist, the backend will try to write in
the current working directory. Flatbed scanners also make use of the
calibration file as a cache to avoid calibration before each scan. Cal‐
ibration file name is the name of the scanner model if only one scanner
is detected. In the case of several identical model, the file name will
be the name of the logical USB device name. The expiration time manages
the time a calibration is valid in cache. A value of -1 means forever,
0 means no cache.
Optionen:
--clear-calibration
Clear calibration cache data, triggering a new calibra‐
tion for the device when the next scan will happen.
--calibration-file
Specify the calibration file name to use. At least the
directory containing the file must exist, since it won't be cre‐
ated. This option is disabled if the backend is ran as root. It
maybe used in case of sheet-fed scanners to share a calibration
file for several users.
Du kannst in xsane mal nachsehen, ob dort ein Schalter für kalibrieren vorhanden ist oder per scanimage --calibrate eine neue Kalibrierdatei erzeugen lassen.
