Patent ID: 8317285

Claim:
A printer that is configured to print an identification card or a passport, comprising: a print station having a print mechanism with a print head configured for printing on the identification card or the passport; a transport mechanism in the print station that transports the identification card or the passport input into the print station in a transport direction; a first sensor capable of sensing an edge of the identification card or the passport to ready the print head for printing; a second sensor downstream from the first sensor in the transport direction and spaced from the first sensor by a fixed distance, the second sensor capable of sensing the edge of the identification card or the passport to initiate printing by the print head; the first sensor and the second sensor are adjustably mounted together for simultaneous change in position in the transport direction within the print station so that the fixed distance between the first sensor and the second sensor remains the same; and the first sensor and the second sensor are disposed on an upstream side of the print mechanism and sense a trailing edge of the identification card or the passport; and further comprising a third sensor that is capable of sensing a leading edge of the identification card or the passport to ready the print head for printing, and a fourth sensor downstream from the third sensor, the fourth sensor is capable of sensing the leading edge of the identification card or the passport to initiate printing by the print head; the third sensor and the fourth sensor are disposed on a downstream side of the print mechanism; and the third sensor and the fourth sensor are adjustably mounted together for simultaneous change in position in the transport direction within the print station.
