Abstract: Examples of the method may comprise providing a print media under a printhead of the printing system, obtaining an actual height profile signal, related to a height between the printhead and the print media, based on measurements taken at a plurality of positions across the width of the media during at least one pass, comparing said actual height profile signal to an earlier height profile signal, obtained based on measurements taken at said plurality of positions across the width of the media during at least one earlier pass on the same print media, and determining a media malfunction condition based on said comparison.
Abstract translation: 该方法的示例可以包括在打印系统的打印头下方提供打印介质，基于在跨越打印头的宽度的多个位置处进行的测量获得与打印头和打印介质之间的高度相关的实际高度分布信号 所述介质在至少一次通过期间将所述实际高度分布信号与先前的高度分布信号进行比较，所述早期高度分布信号是基于在相同的打印介质上的至少一次以前的传播期间穿过所述介质的宽度在所述多个位置处进行的测量而获得的，以及 基于所述比较确定介质故障状况。

Abstract: The present disclosure discloses a method implemented by a printer to control a fluid firing unit of a printhead, when said printhead is coupled to the printer, to operate according to any one of a normal printing mode and a recovery mode. According to the method, if the fluid firing unit is operated according to the normal printing mode, a first voltage is applied to the fluid firing unit to fire the fluid firing unit during a printing operation; and if the fluid firing unit is operated according to the recovery mode, a second voltage higher than the first voltage is applied to the fluid firing unit to clean the fluid firing unit.
Abstract translation: 本公开公开了一种打印机实现的方法，当所述打印头与所述打印机连接时，根据正常打印模式和恢复模式中的任何一种来操作打印头的流体点火单元。 根据该方法，如果流体点火单元根据正常打印模式操作，则在打印操作期间将第一电压施加到流体点火单元以对流体点火单元进行点火; 并且如果根据恢复模式操作流体点火单元，则将高于第一电压的第二电压施加到流体点火单元以清洁流体点火单元。

Abstract: A printing apparatus includes a media support assembly, a scanning module, and a control module. The media support assembly may position a respective media portion in a print zone to receive a printing fluid thereon. The scanning module may scan the media portion in the print zone and generate a media shape signal corresponding to a shape of the media portion. The control module may compare the media shape signal to a reference signal to form a resultant comparison and determine a media malfunction event based on the resultant comparison.
Abstract translation: 打印装置包括介质支撑组件，扫描模块和控制模块。 介质支撑组件可将相应的介质部分定位在打印区域中以在其上接收打印流体。 扫描模块可以扫描打印区域中的介质部分，并产生对应于介质部分的形状的介质形状信号。 控制模块可以将介质形状信号与参考信号进行比较以形成合成的比较，并且基于所得到的比较来确定介质故障事件。
