Abstract: A printer filter packaging apparatus includes a base for supporting a filter having delicate filter media. Side wraps extend from two opposite sides of the base and cover two opposite sides of the filter. A rear wrap includes a handle, and covers a rear and a top of the filter. A front wrap defines a slit for receiving the handle; the front wrap covers the top and a front of the filter. The wrapped or covered filter may be lifted by the handle, the filter being supported by a combination of the base and front, rear, and side wraps.

Abstract: A printing apparatus includes a printhead module having an ink leakage detector to detect a leaked phase change ink. The ink leakage detector includes a plurality of resistance temperature detectors or resistive thermal devices to detect the leaked phase change ink. A horizontally mounted overdriven thermistor can also be used to detect leaked ink.

Abstract: An ink delivery system for transporting thermally treated ink from different ink reservoirs to multiple print he ads of an imaging device includes a rigid injector assembly, and multiple pliable tubes attached to the injector assembly. The injector assembly includes two T-shaped members made of a conducting material, positioned one a top the of her. Each of the two members has grooves provided within it. The grooves within one of the members align with the grooves within the other member, to create channels, which carry ink to the pliable tubes. The pliable tubes are made of a flexible material, such that the lower end of each pliable tube is freely movable with respect to the injector assembly. A heating mechanism surrounds the injector assembly and the pliable tube, and remains in thermal communication with the system, to keep the ink in molten state all through the transportation path within the ink delivery system.

Abstract: This is an environmental unit useful in a xerographic system that reduces or eliminates pulsation and vibration in the system. This is accomplished by the use of flexible bladders on a wall of the air duct work pumping air into the print housing. When the vibration is abated, the banding problems on images are eliminated.

Abstract: This is a waste cyclone toner dispense system with a controlled gate and a collection bag below the gate. The controlled gate is configured to be opened and closed at a predetermined time thereby permitting the use of relatively inexpensive bags for collection of toner debris. The gate is hinged to permit easy opening by a controller and motor. The controller turns off any pressure while the gate is open. The drop gate conveys when open waste toner from an upper waste collection funnel to the collection bag.

Abstract: This is a novel xerographic marking system having a novel toner waste dispensing assembly. The assembly comprises a hermetically sealed outer box that houses a disposable waste toner container. The container is a biodegradable carton or bag that can be removed from the outer box when filled with waste toner. A feature of this invention is that the dispensing assembly can easily be retrofitted into existing marking systems. Also because the containers are inexpensive and biodegradable, the expensive prior art non-degradable waste containers and their adverse effect on the landfills can be avoided.

Abstract: This is a waste cyclone toner dispense system with a controlled gate and a collection bag below the gate. The controlled gate prevents pressure from entering the bag thereby permitting the use of relatively inexpensive bags for collection of toner debris. The gate has rotating blades tightly pushed against a sealing wall, such as rubber or the like. The wall must prevent pressure from reaching the bag and remaining only above the bag. The rotating blades convey waste toner from an upper collection to the collection bag.

Abstract: This is a toner control system for use in a cleaning station of a xerographic marking apparatus. A sensor is located in the air conduits of the system to measure airflow throughout the system. The sensor is in contact with a controller that is configured to adjust the blower speed to normal conditions (i.e. sea level and clean filter conditions) as the flow rate is reduced due to normal apparatus use. The system has an air blower(s), a filter(s), air conduits, a sensor(s) and a controller(s) in communication with the sensor(s).

Abstract: 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.

Abstract: 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.
