发明名称 Methods of moving a media sheet from an input tray and into a media path within an image forming device
摘要 The application is directed to methods for moving a media sheet through the media path of an image forming device. In one embodiment, the media sheet may be moved by a pick mechanism having a pick roll from an input tray. The pick roll in the input tray may maintain contact with the media sheet and drive the sheet at a first elevated speed as it moves towards the nip. The pick roll may then slow as it brings the leading edge into contact with the nip. This slower speed may reduce the amount of nip shock or compression that may cause reengagement of the pick mechanism and an unintentional double sheet feed. Moving the media sheet at the fast speed a majority of the distance along the media path between the input tray and nip may increase media throughput.
