in fact this should not happen. The scan in general starts
after inserting the sheet. BUT: on startup the paper sensor
will be asked and if it detects paper the driver ejects it,
after that the driver waits for inserting the next sheet.
So the procedure, insert, start scanimage, scan will not work.
Start scanimage, insert sheet, scann should work

The calibration is done with a plain white sheet. The driver does
the black calibration by switching off the light and not by reading
black marks on a calibration sheet - that's the difference.
