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。
