A safe tiltable sheet feeding apparatus including a tiltable sheet support tray having a lead edge and a trail edge, for supporting a stack of sheets to be fed lead edge first from the stack. The tiltable sheet feeding apparatus also includes a feed head adjacent the sheet support tray for feeding a top sheet of the stack from the stack and an elevator assembly for independently raising, lowering and tilting the trail edge of the sheet support tray. The elevator assembly includes elevator drive motors, a controller, side frames defining lead edge elevator slots, and trail edge elevator slots. Importantly, the tiltable sheet feeding apparatus includes an overtilt safety sensor device mounted within the trail edge elevator slots and connected to the controller, for sensing overtilt of the trail edge of the sheet support tray, and for preventing resulting damage to the tiltable sheet feeding apparatus.

A modular control assembly for controlling a plurality of electromechanical components in a printing machine for producing prints on a substrate is provided. The assembly includes a body, a plurality of electrical components mounted onto the body. The assembly further includes a plurality of electrical conduits. Each of the conduits is electrically connected to at least one of the electrical components. The assembly further includes a plurality of electrical connectors. Each of the connectors is electrically connected to at least one of the electrical conduits. The electromechanical components are quickly electrically connectable and disconnectable to the assembly at the connectors.

Modular control assembly for xerographic printer

A commutating connector which electrically connects conductive paths of a rotating electroded donor roll to a voltage source. The connector includes a housing made of an electrically insulating material. The housing defines a chamber to receive the donor roll. An electrically conductive brush is disposed in the chamber. The brush is mounted in pressing engagement against the conductive paths on the electroded donor roll to electrically connect the voltage source to the conductive paths on the electroded donor roll. The chamber is divided by a partition into a commutating and a non-commutating area. The housing has ports for receiving air to prevent particulate matter from accumulating between the brush and donor roll.
