A printing device includes an input tray in which sheets of media are loadable and a media guide movably adjustable along a dimension of the input tray and positionable against the sheets. The printing device includes a drive conductor electrically exposed parallel to the dimension of the input tray, detect conductors differently electrically exposed parallel to the dimension of the input tray, and a cross-conductor disposed on the media guide. The cross-conductor selectively electrically connects the drive conductor with the detect conductors according to a current media guide position to permit detection of the current media guide position.
