ABSTRACT:
The invention is a printer for labels which can determine when the label stock is in position for printing. The printer comprises a print head and label stock having labels on a first side and indicator stripes printed on a second side. The printer uses an emitter for producing infrared light and a detector for receiving the light. A mirror is used to focus and reflect the light, the mirror is positioned with respect to the emitter, detector and label stock so as to reflect light originating at the emitter to the label stock and from the label stock to the detector. The invention is also drawn to the cassette used in the label printer comprising a base, a retainer on the base containing a roll of label stock, a guide plate having a window therein for conveying the label stock, a concave mirror mounted on the cassette adjacent the window, and a sensor hole on the base of the cassette through which light from an emitter and detector passes. The concave mirror is positioned with respect to the window and the sensor hole such that light emitted from an emitter is reflected from the mirror to the label stock and from the label stock to a detector wherein the guide plate, the window, the mirror and the sensor hole are aligned with each other such that the indicator stripe on the label stock can be detected.
