Abstract: A media supply system (40) suitable for use in an imaging apparatus (30) to remove sheets of imaging media from a stack of one or more sheets of imaging media. Media supply system (40) includes a pickup assembly (50) and an actuator system (52). Pickup assembly (50) is moveable between at least a first position and a second position, wherein at least a portion of the pickup assembly is configured to selectively engage a first sheet of imaging media of the stack when the pickup assembly is in the first position. Actuator system (52) is selectively coupled to pickup assembly (50) and is configured to move pickup assembly (50) between at least the first position and the second position and to vibrate at least the portion of the pickup assembly engaging the first sheet of imaging media at a desired frequency after moving the pickup assembly from the first position, wherein the desired frequency is based on characteristics of the sheets of imaging media.

Abstract: An actuator system for use with a sheet transport system having a first roller and a second roller. The actuator system includes an idler assembly and a drive assembly. The idler assembly is coupled to the first roller and is biased to hold the first roller in a closed position engaging the second roller for transporting a sheet. The drive assembly is configured to engage the idler assembly to move the first roller between an open position spaced from the second roller and the closed position and to disengage the idler assembly when the first roller is in the closed position so that the first roller is held in the closed position solely by the idler assembly.

Abstract: A mechanical element having a slot adapted to receive a shaft. The slot comprises a circular portion; a planar portion; and two reliefs. Each relief is disposed intermediate the circular portion and the planar portion. In addition, each relief comprises a circular section and extends at least about 90 degrees. Each relief is coupled to the planar portion by a radius tangential to the planar portion.

Abstract: A system for opening and closing a resealable cartridge having a tray and a flexible cover resealably engaged with the tray. The system comprises: a base for receiving the tray of the cartridge; a roller shaft having means for engaging the cover of the cartridge; positioning means operably connected to the roller shaft to affect positioning of the roller shaft relative to the cartridge between a first position wherein the roller shaft is spaced from the cartridge and a second position different from the first position wherein the roller shaft is not spaced from the cartridge; and a motor for rotating the roller shaft in a first rotational direction to wind the cover about the roller shaft, thereby removing at least a portion of the cover from the tray, and for rotating the roller shaft in a second rotational direction to unwind the cover from the roller shaft thereby resealably engaging the cover with the tray.
