Theory of Operation
Card Movement During Printing
• The last time the Main Cover was opened and closed, the ribbon was automatically
“synchronized,” thereby bringing the leading edge of the Black (K) ribbon panel under
the Printhead.
• The leading edge of the card is moved under the Printhead, the Printhead is lowered, and
printing begins.
• After this Black pass is completed, the Printhead is raised; and the card is moved to the
Card Flipper. The card is turned over and is moved back through the printer so the other
side of the card can be cleaned.
• If the printer includes an optional Smart Card Encoder Station, the card is moved to the
Station and encoded.
As the card is encoded, it is checked to verify that it was encoded properly.
If encoding fails, the card is moved past the Printhead directly to the Card Exit and
into the Card Output Hopper. As for a failed Magnetic Stripe Encoding, this is done to
avoid wasting time and ribbon panels on a defective card.
• The leading edge of the card is moved under the Printhead, and the Printhead is lowered.
• Printing continues with the Yellow (Y) ribbon panel, the Magenta (M) panel, the Cyan (C)
panel, and the Black (K) panel.
• When printing is completed, the card is moved to the Card Flipper, raised, and pushed by
the Eject Arm into the Laminator.
• As the card passes through the Laminator, the upper and lower Transfer Rollers apply a
patch of laminating film to the card. At the same time, laminating film is measured, cut,
and rolled onto the Transfer Rollers for the next card.
• The card (with the patch of laminating film) then passes between a pair of heated rollers,
which seals the laminating film to the card.
• The card is moved from the Laminator to the Card Exit, where it falls into the Card
Output Hopper.
