Entrance guide for friction/retard feeding systems |
摘要 |
A substrate feeding system, and printers that use such feeding systems, that includes a feed roll and a retard roll that form a nip, a nudger roll for advancing a substrate from a substrate stack toward the nip, and an entrance guide between the nudger roll and the nip. The entrance guide has a contact surface that forms an angle of more than 100 DEG with the direction of motion of the substrate. The entrance guide further including a top section over which the substrate moves as it advances into the nip. The entrance guide is beneficially pivotally mounted such that when a retard roll is removed the entrance guide pivots out of the way, and such that when a retard roll is in place the entrance guide moves into position.
