Abstract: A diverter to direct media within an image forming apparatus along one of three media paths. A first gate and a second gate are positioned in an overlapping arrangement and each is movable between up and down positions. Each of the gates includes a biasing member to bias the gates towards the down position. An actuator contacts the second gate to move it to the up position. The overlapping arrangement of the first and second gates causes the first gate to also be moved to the up position when the second gate moves to the up position. A second actuator contacts the first gate to move the gate from the down position to the up position independently of the second gate.

Abstract: An imaging apparatus includes a machine frame, a printhead housing containing a printhead for generating a laser beam, and a position sensing device. The position sensing device includes a position sensing device frame and a position sensor for sensing a position of the laser beam. The position sensing device frame is interposed between the machine frame and the printhead housing. Each of the machine frame, the printhead housing and the position sensing device frame include at least one reference feature that in combination accurately reference the position of the printhead housing to the machine frame.

Abstract: A printer has one or more stacked sheet output units on top of it for increasing the printer's output capacity. Each unit includes a housing having a diverter as does the printer. The position of each diverter is controlled by a diverter/drive mechanism in the unit stacked on top of it. In its first position, the diverter of the printer or the unit diverts a fed sheet from a substantially vertical path therein to a sheet receiving area. In its second position, the diverter allows the fed sheet to be advanced by driven rolls to the unit thereabove. The feed rolls of a unit are driven only when the diverter in each of the printer and in any unit therebeneath are in the second position.
