If the card reader can't complete a
calibration on the leading edge of the ballot, then the reader sends 0's on
it's SCANDATA signal to the AccuVote. The AccuVote gets no timing marks
and sees this ballot as a blank paper.
Yep.
Uncalibrated scans can
happen for a few reasons. The leading edge being fed can be dirty
or smudged, the ballot may be printed on colored paper stock that is out
of spec, a corner may be torn out of the ballot, etc.
Don't forget
interference due to cosmic rays.
Whether the ballots
have bad Karma or not is probably not worth debating. They read fine the
second time.
