Stef,
On my Visioneer Strobe XP 100, revision 3, I can calibrate and clear calibration from within XSane without a problem.

But when I try:
$scanimage -d genesys --clear
or
$scanimage -d genesys --calibrate
I get the following:
scanimage: sane_start: Error during device I/O

(With the command line calibrate, it does feed the calibration sheet into the scanner, just like it does with xsane).

So, maybe Andrey could try to calibrate using xsane, instead of the command line. In xsane, click on the "window" tab and check "show advanced options" and you should get a calibrate button.
