    摘要: A method and apparatus for controlling curl in a liquid ink printer. The liquid ink printer deposits an anticurl material on the side of a printed sheet opposite the one having printing deposited thereon. The anticurl material is a fluid which counteracts the steady state curl in the direction of the printed image resulting from active drying of the printed sheet. The back side of a printed sheet has deposited thereon an anticurl fluid which can contain water, a penetrant, and a humectant like material such as diethylene glycol, ethylene glycol, sulfolane and glycerin. The anticurl material is deposited with a roller made of a foam material for absorbing the anticurl fluid or a roller having dimples disposed on the surface thereof. In addition, the anticurl fluid can be deposited by a spray device or a thermal ink jet printhead ejecting anticurl fluid.

    摘要: An electrostatic microelectromechanical system (MEMS) based fluid ejector comprises a movable piston structure and a stationary faceplate. A fluid chamber is defined between the piston structure and a substrate. The piston structure 110 may be resiliently mounted on the substrate by one or more spring elements. A fluid to be ejected is supplied in the fluid chamber from a fluid reservoir through a fluid refill hole formed in the substrate. The faceplate includes a nozzle hole through which a fluid jet or drop is ejected. In various exemplary embodiments, the piston structure moves towards the faceplate by electrostatic attraction between the piston structure and the faceplate. As a result of the movement of the piston structure, a portion of the fluid between the piston structure and the faceplate is forced out of the nozzle hole, forming a jet or drop of the fluid.

    摘要: A boundary layer disturber for removing heat from the platen of a copier is in the form of an improved scanning reflector which has a portion thereof in the form of a "scoop". During scanning motion, the reflector entrains air flow which disturbs and peels the thermal boundary layer from underneath the platen glass, thus passively improving platen glass cooling. Also, the reflector is contoured to allow air to entrain over the lamp assembly, resulting in enhanced cooling. As a result of changing the form of the reflector there is increased cooling characteristics in the optics cavity, thus allowing blowers with lower power and noise levels to be utilized in the optics cavity.

    摘要: A recording element printing and treating system and method are provided. The system includes a printhead for dispensing a liquid comprising a carrier onto a recording element. A carrier removal station positioned downstream from the printhead removes a predetermined percentage of carrier present in the recording element. A converting station positioned downstream from the carrier removal station increases a durability characteristic of the recording element. In one embodiment, printing, carrier removal, and converting are accomplished in a single unit. In an alternative embodiment, printing is accomplished in a stand alone unit while carrier removal and converting are accomplished in a second stand alone unit. In this alternative embodiment, transfer of the recording element can be accomplished automatically using a mechanical device or manually by a system user.
