Abstract
Paper tray (3) has a camming surface (60). Sets of nip rollers (22 and 24; 26 and 28) are permanent in the printer. One of set of nip roller is pivotally mounted and biased by springs (50, 56) to a follower (54). With the tray inserted, the follower is cammed to stretch the springs to apply desired nip force. The height of the cam surface may be varied to change that force for different paper contained in the tray. With the tray removed, the nip force is removed and jammed paper may be easily removed, particularly since area of the nip rollers is close to the front of the machine and near the opening left when the tray is removed.
