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.

A print media detection apparatus may include a movable scanner bar for scanning media, a feeder tray for supplying the print media, a print media indicator and a controller. The print media indicator may include a first portion to interact with the print media within the feeder tray and a second portion coupled to the first portion to move in response to movement of the first portion. The scanner bar is to sense the second portion of the media indicator. The controller is to determine a characteristic of the print media within the feeder tray based upon sensing of the second portion by the scanner bar.

In a method for compensating for media linefeed errors in a media feed apparatus, a first correction parameter is applied during a first length of a media feed operation and a second correction parameter, which differs from the first correction parameter, is applied during a second length of the media feed operation.
