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.
