Abstract

A plastic card printer that is provided with a printhead guard that is movable between a covering position, where the printhead guard covers one or more sensitive portions of a printhead of the plastic card printer, and a non-covering position, where the printhead guard does not cover the one or more sensitive portions of the printhead thereby allowing the printhead to perform a printing function on a plastic card. The printhead guard can be at the covering position when the printhead is at a non-printing position, for example during servicing of the card printer, to protect the one or more sensitive elements when the printhead is at the non-printing position, and the printhead guard can be at the non-covering position when the printhead is at a printing position where the printhead is ready to perform printing.

Claims (22)

1. A plastic card printer, comprising:

a card input through which a plastic card is input for printing;

a printhead that is configured to print onto the plastic card, the printhead is movable between a printing position at which the printhead can print onto the plastic card and a non-printing position at which the printhead cannot print onto the plastic card;

a printhead guard associated with the printhead, the printhead guard is movable relative to the printhead between a covering position where the printhead guard covers the printhead and a non-covering position where the printhead guard does not cover the printhead; and

wherein the printhead guard is at the covering position when the printhead is at the non-printing position, and the printhead guard is at the non-covering position when the printhead is at the printing position.

2. The plastic card printer of claim 1 , further comprising a card transport mechanism that transports the plastic card from the card input to the printhead for printing on the plastic card.

3. The plastic card printer of claim 1 , wherein the printhead guard is automatically movable from the non-covering position to the covering position as the printhead is moved from the printing position to the non-printing position, and the printhead guard is automatically movable from the covering position to the non-covering position as the printhead is moved from the non-printing position to the printing position.

4. The plastic card printer of claim 1 , wherein the printhead is a thermal printhead with a dot row; and further comprising a print ribbon associated with the printhead.

5. The plastic card printer of claim 4 , wherein the print ribbon comprises a plurality of cyan, magenta, yellow and black panels.

6. The plastic card printer of claim 4 , further comprising a printer housing having a panel that is pivotable between a closed position and an open position; and the printhead is fixed to and movable with the panel whereby the printhead is at the printing position when the panel is at the closed position and the printhead is at the non-printing position when the panel is at the open position.

7. A plastic card printer, comprising:

a printer housing that has a panel that is pivotable between a closed position and an open position;

a card input hopper attached to the printer housing, the card input hopper is configured to hold a plurality of plastic cards to be printed on;

a print station within the printer housing at which a plastic card fed from the card input hopper is printed on, the print station including a thermal printhead with a dot row, and a removable print ribbon;

the thermal printhead is fixed to and moveable with the panel for movement between a printing position at which the thermal printhead can print onto the plastic card and a non-printing position at which the thermal printhead cannot print onto the plastic card; the thermal printhead is at the printing position when the panel is at the closed position and the thermal printhead is at the non-printing position when the panel is at the open position;

a printhead guard associated with the thermal printhead, the printhead guard is movable relative to the printhead between a covering position where the printhead guard covers the dot row of the thermal printhead and a non-covering position where the printhead guard does not cover the dot row of the thermal printhead; and

wherein the printhead guard is at the covering position when the thermal printhead is at the non-printing position, and the printhead guard is at the non-covering position when the thermal printhead is at the printing position.

8. The plastic card printer of claim 7 , wherein the printhead guard is automatically movable from the non-covering position to the covering position as the thermal printhead is moved from the printing position to the non-printing position, and the printhead guard is automatically movable from the covering position to the non-covering position as the thermal printhead is moved from the non-printing position to the printing position.

9. The plastic card printer of claim 7 , wherein the print ribbon comprises a plurality of cyan, magenta, yellow and black panels.

10. The plastic card printer of claim 7 , wherein the printer housing includes a front, back, top, bottom, first side and second side; and the panel is disposed at the top of the printer housing.

11. The plastic card printer of claim 10 , wherein the card input hopper is disposed at the front of the printer housing.

12. The plastic card printer of claim 11 , wherein the printer housing further includes a card outlet that is disposed at the front.
