Remove the metal cover by removing the screws along the bottom left edge and one in the rear top right corner, and loosening the ones at the hinge in the top center. Then remove the screw on the media sensor, and pull the ribbon cable out of it's socket. The sensor slides out from the circuit board side of the center plane.

It's called "Present Distance" and it can be set to "0" in the printer's control panel. Look under Print Control.

There's a "Media Sensor" in the Datamax that is evidently having trouble seeing the labels. The sensor is inside of a horizontal bar above the labels and just behind the Printhead. That bar is movable. Make sure that the vertical mark, usually white, is positioned over the label - best if it is the center of the label. Also make sure that there is no label or ribbon material stuck in that area. Hold "Feed" button down for a few seconds after checking those two things to "Re-calibrate" the sensor.
