A card singularization gate for use in an identification card printer includes a roller support, a guide roller, and a card stop. The roller support is positioned between a card feeder and the card transport mechanism. The guide roller is supported by the roller support for rotation about an axis that is substantially parallel to a card feed plane and transverse to a card path. The guide roller includes a card engaging side adjacent the card feed plane where non-abrasive contact of a first surface of the lead card is made during the card feed operation. The card stop is positioned adjacent a side of the guide roller that is opposite the card engaging side. During card feed operations, the lead card is allowed passage to the card transport mechanism along the card engaging side of the guide roller while cards that are stacked upon the lead card are blocked by the card stop.
