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.

摘要： A method of determining a relative speed between two separately driven members in an image forming apparatus, includes the steps of: transporting a print medium using a print media transport assembly including an exit nip, the print media transport assembly operable at a first transport speed; driving a rotatable member associated with an entrance nip using an electric motor at a second transport speed which is independent from the first transport speed; transferring the print medium from the exit nip to the entrance nip; detecting an electrical characteristic of the motor when the print medium is present in each of the exit nip and the entrance nip; and determining a relative speed between the first transport speed and the second transport speed.
