The ribbon synchronizes to it’s “starting” position whenever the Print Cover is opened
and then closed. For a YMCKO ribbon, the starting position is with the leading edge of
a Yellow Panel at the printhead location.
The figure below shows how the YMCKO ribbon and card move relative to each other
during printing.

printed on either side of the card.
