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 media tray assembly for a printer includes an output tray that is removably and pivotally mounted onto an input tray. The output tray is configured such that it can be easily installed into and quickly removed from the printer. In addition, the output tray can be pivoted upward from a substantially horizontal position and latched into an inclined position in one continuous motion by a user.

A pick-up mechanism and a method for performing a pick-up cycle in a reproduction machine. The pick-up mechanism comprises a pick-up control pinion which is firmly coupled to a control cam, and a drive gearing including a first rocker driving gear and a second rocker driving gear. The first and second rocker driving gears are mounted to a rocker device to be alternately engaged into and disengaged from, respectively, the pick-up control pinion. Upon starting the pick-up operation, the second rocker driving gear is drivingly engaged into a toothed section of the pick-up control pinion, and, in the course of the pick-up operation, the first rocker driving gear is drivingly engaged into the toothed section of the pick-up control pinion.

A sheet media handling system for aligned feeding of sheet media of different widths is disclosed. This sheet media handling system caters to a wide-format printer which has two media trays, a main tray and a bypass tray positioned above the main tray. In such a printer, a larger width sheet medium in the bypass tray is insufficiently supported when a stack of smaller width sheet media is present in the main tray. Such a situation may result in skewing or jamming of the larger width sheet medium. The sheet media handling system overcomes such a problem by having a secondary pressure plate in addition to a primary pressure plate. This secondary pressure plate is moveable independently of the primary pressure plate so that the secondary pressure plate is operable to provide appropriate support for the partially supported larger width sheet medium in the bypass tray.
