Abstract: A pick attempt of a media sheet from a media tray is initiated by rotating a pick roller a number of rotations that is set to greater than one in response to the sheet having been designated as a special media sheet type and that is set to one in response to the sheet not having been so designated. In response to a pick sensor detecting the sheet after the pick attempt has been attempted, a turn roller is rotated to advance the sheet to a print engine, and while the turn roller is rotating, the pick roller is rotated to assist advancement of the media sheet. A controller manages per-sheet and per-tray pick attempt counters while the sheet is individually attempted to be picked and advanced, using the counters to determine whether to initiate another pick attempt of the sheet when a current pick attempt has failed.

Abstract translation: 响应于已被指定为特殊介质薄片的薄片，通过旋转拾取滚轮多次旋转来启动介质薄片从介质托盘的拾取尝试，所述多次旋转被设定为大于1 类型，并且为了响应未被指定的纸张而设置为1。 响应拾取传感器在尝试拾取尝试之后检测到片材，旋转转动辊以将片材前进到打印引擎，并且在转动辊转动的同时，拾取辊旋转以协助介质的前进 片。 一个控制器管理每张纸张和每个纸盒的拣货尝试计数器，同时分别尝试拣配和提前纸张，使用计数器确定在当前拣配尝试失败时是否启动纸张的另一次拣配尝试。
