Methods of the present invention relating to an identification card printer include a method of calibrating a ribbon sensor for detecting transition portions between adjoining panels of a ribbon and a method of calibrating tension in a ribbon. Identification card printers in accordance with embodiments of the invention include a sensor positioned downstream of a printhead relative to a feeding direction of a ribbon; support for a printhead that is moveable between print and withdrawn positions; a swing frame supporting a first roll of a ribbon for rotation about an axis about which the swing frame pivots; an adjustable card guide in line with a print path; and a card bender including a pinch roller assembly having first and second rollers, axes of rotation of which are aligned in a plane that is non-perpendicular to a card path.
