Abstract
A sensor apparatus for providing two sensing operations within a thermal printer includes a densitometer with at least one light source that discriminates color and that is positioned in a first position for sensing donor patches within the thermal printer; the densitometer while in a second position provides signals from printed receiver media for internal color calibration of the thermal printer. At least one reflector directs light from the light source to the densitometer through a donor web when the densitometer is in the first position; and a switchable device repositions the densitometer from either the first position or the second position.
