    • A printing apparatus comprises a paper path adjacent a media supply. The paper path moves printing media from the media supply through the printing apparatus. Also, a marking engine is positioned adjacent the paper path, and the paper path supplies the printing media to said marking engine. The marking engine prints marking material on the printing media in a printing process, and the printing process generates vapors and ultrafine particles. The printing apparatus includes ducting adjacent the paper path and the marking engine. A fan is positioned within the ducting. The fan moves the vapors and ultrafine particles from around the paper path and the marking engine into the ducting. Further, at least one condensation unit is located within the ducting. The condensation unit is maintained at a temperature sufficient to condense and collect the vapors and ultrafine particles. The condensation unit comprises a base and poles extending from the base, the poles (which can comprise rods, pins, carbon nanotubes, etc.) are sized to maximize condensation and collection of the vapors and ultrafine particles.
    • 打印设备包括邻近媒体供应的纸张路径。 纸张路径将打印介质从介质供应通过打印设备移动。 此外,标记引擎位于纸张路径附近,并且纸张路径将打印介质提供给所述标记引擎。 标记引擎在打印过程中在打印介质上打印标记材料,并且打印过程产生蒸气和超细颗粒。 打印设备包括邻近纸张路径和标记引擎的管道。 风扇位于管道内。 风扇将蒸气和超微粒从纸路径和标记引擎移动到管道中。 此外,至少一个冷凝单元位于管道内。 冷凝单元保持在足以冷凝和收集蒸气和超细颗粒的温度。 冷凝单元包括从基座延伸的基极和极,极(其可以包括杆,引脚,碳纳米管等)的尺寸被设计成使蒸气和超微粒子的冷凝和收集最大化。

    • A printing apparatus comprises a marking device, a media path positioned to supply sheets of media to the marking device, and a media supply tray positioned to supply the sheets of media to the media path. Further, a pair of rollers forms a nip adjacent the media supply tray. The rollers rotate in opposite directions to cause the sheets of media to move from the media supply tray to the media path. Additionally, a first frame structure supports a first roller of the pair of rollers. The first frame structure can be in a fixed position and holds the first roller in a fixed location. A second frame structure supports a second roller of the pair of rollers. The second frame structure is adjustable in a first direction toward the first roller and has a variable pivot position allowing the second frame structure to move in a second direction perpendicular to the first direction.
    • 打印装置包括标记装置,定位成向打标装置提供纸张的介质路径,以及定位成将介质片材供应到介质路径的介质供应盘。 此外,一对辊形成邻近介质供应托盘的辊隙。 滚筒沿相反方向旋转,使介质片从介质供应托盘移动到介质路径。 此外,第一框架结构支撑该对辊的第一辊。 第一框架结构可处于固定位置并将第一辊保持在固定位置。 第二框架结构支撑该对辊的第二辊。 所述第二框架结构在朝向所述第一辊的第一方向上是可调节的并且具有允许所述第二框架结构在垂直于所述第一方向的第二方向上移动的可变枢转位置。
