An airborne toner collection manifold for an electrostatographic printer for coupling in fluid flow communication with a vacuum source includes an inlet, a collection duct, a first exhaust duct and a second exhaust duct. The inlet defines a gap slot extending longitudinally between a first end and a second end. The collection duct is adjacent to the inlet and has a first end extending longitudinally at least to the first end of the gap slot of the inlet and a second end extending longitudinally at least to the second end of the gap slot of the inlet. The collection duct defines a cavity in fluid flow communication with the gap slot. The first exhaust duct is in fluid flow communication with the cavity of the collection duct and is configured to be coupled for fluid flow communication with the vacuum source. The second exhaust duct is in fluid flow communication with the cavity of the collection duct and is configured to be coupled for fluid flow communication with the vacuum source. The second exhaust duct is displaced from the first exhaust duct and is positioned relative to the first exhaust duct to be closer to the second end of the collection duct.

Manifold for toner collection and contamination control in xerographic process developer housing

An apparatus for developing a latent image recorded on a movable imaging surface, including: a reservoir for storing a supply of developer material including toner particles, the reservoir including a developer material mixing and transport area; a donor member being arranged to receive toner particles from the reservoir and to deliver toner particles to the image surface at locations spaced apart from each other in the direction of movement of the imaging surface thereby to develop the latent image thereon; and a climate system, associated with the reservoir, for maintaining the supply of developer material at a predefined temperature, the climate system includes a cooling element for supplying cool air to the developer material mixing and transport area, and a heating element positioned within air path for heating air to predefined temperature.

Heating system for a developer housing

An electrophotographic marking device includes a xerographic marking module and an environmental control module which controls temperature and relative humidity inside the marking module. The environmental module has a main plenum chamber and a divided or split plenum chamber to create and supply two air streams with different temperatures and/or different humidities and/or different airflow volumes and/or airflow rates to a marking engine. A primary air stream plenum chamber is closed loop controlled by input from one or more temperature and/or humidity sensors in the xerographic module. A secondary air stream plenum chamber is open loop controlled by means of one or more temperature and/or humidity sensors in one or mode developer housings. Heating of the secondary air stream is achieved by heat generated in the developer housing(s) and/or one or more heaters distinct from the developer unit elements. The system achieves balanced, thermodynamically adjusted, air flows.

Fuser apparatus for heat fusing toner images to a print substrate has a fuser roll and a pressure roll forming a fusing nip therebetween, a system to deliver liquid release agent to the fuser roll including a movable web having a first side and a second side supported between a web supply roll and a web take-up roll, a housing supporting the supply roll and take-up roll such that one of the supply and take-up rolls is on one side of the fuser roll and the other is on the other side of the fuser roll and the first side of the movable web is in contact with the fuser roll along a path parallel to its longitudinal axis. The movable web is impregnated with a liquid release agent and the movable web, supply roll and take-up roll are reversibly mounted in the housing to deliver liquid release agent to the fuser roll initally from the first side of the movable web followed by reversing the location of the supply roll and take-up roll in the support housing so that the second side of the impregnated web is in contact with the fuser roll to deliver release agent. The movable web is urged into delivery engagement with the fuser roll by an open celled foam pinch roll impregnated with liquid release agent.
