摘要： A computer printer having a frame contained within a housing, a media transport and printing mechanism attached to the frame within the housing is provided with at least one debris shield positioned above the printing mechanism to protect it from falling debris. The at least one debris shield may be positioned below an air flow path generated by printer ventilation, and the printer may employ a transfer surface on which an image is generated prior to transfer to a media sheet, and above which the debris shield is positioned. Stripper fingers strip the media sheet from the transfer surface and webs between the stripper fingers form an air flow barrier to prevent debris transmission through gaps between the fingers.

摘要： A method and an apparatus (10) for cleaning an ink jet print head (12) draws contaminates from orifices (20) in the print head onto an orifice plate (14) and then wipes the orifice plate. The maintenance apparatus includes a purge cap (24) that has a recessed region (40) with an open end (36). The top side margins (42) of the open end define a periphery (44) around which a seal (60) is positioned. A positioning system (30) urges the orifice plate against the seal. A heating system (128) and a vacuum system (74) cooperate to create a differential pressure across the orifices to draw contaminates carried by liquid ink out of them and onto the orifice plate. A resilient wiper assembly (26) including a spring-mounted wiper blade (78) is positioned in and nominally extends outwardly of the recessed region of the purge cap. The positioning system moves the purge cap downwardly against the orifice plate so that the wiper blade engages and wipes the contamination from the orifice plate.
摘要翻译： 用于清洁喷墨打印头（12）的方法和设备（10）将污染物从打印头中的孔（20）中抽出到孔板（14）上，然后擦拭孔板。 维护装置包括具有开口端（36）的凹陷区域（40）的净化帽（24）。 开口端的顶侧边缘（42）限定周边（44），密封件（60）围绕该周边定位。 定位系统（30）将孔板推向密封件。 加热系统（128）和真空系统（74）协作以产生穿过孔口的压差，以将液体墨水携带的污染物从它们中抽出并流到孔板上。 包括弹簧安装的刮水片（78）的弹性擦拭器组件（26）定位并且标称地延伸到清除盖的凹陷区域的外侧。 定位系统将吹扫帽向下移动抵靠孔板，使得刮水片与孔板接合并擦拭污染物。
