摘要： The present application is directed to devices for determining the position of a media sheet. An encoder roller is positioned to contact a media sheet. In one embodiment, the encoder roller is positioned within an input area and rests on a top-most media sheet within a media stack. Movement of the media sheet is detected by an encoder. The media sheet is further moved by other means, such as a pick mechanism and transport rollers. The expected movement of the media sheets through these means may be compared to the actual movement detected by the encoder.

摘要： The present application is directed to methods for determining the location and movement of a media sheet within an image forming device. In one embodiment, the media sheet is positioned within an input area of the device. A pick roller is rotated to move the sheet from the input area and into a media path. An encoder roller may be positioned in contact with the sheet to detect the actual movement of the sheet from the input area. A controller may determine the expected amount of movement based on the movement of the pick roller and compare this amount with an actual amount of movement based on the movement of the encoder roller.
