Abstract: A printer fir printing on a print medium includes a base unit with a primary media supply tray. An input option unit is positioned below the primary media supply tray. An output option unit is coupled with the input option unit.

Abstract: A label support for an integrated label, which includes a label portion and a thinner paper portion, includes a base having a support surface with its rear end higher than its front. When the label support is supported by a support surface of a media support tray, its front end is closest to an inclined dam of the media support tray. The label support has at least its rear end spaced from the support surface of the media support tray. In one embodiment, the base of the label support has a first substantially horizontal portion connected by an inclined portion to a second substantially horizontal portion, which rests on the support surface of the media support tray. This embodiment extends for less than the length of the support surface of the media support tray for sliding along the support surface of the media support tray to accommodate varying lengths of the integrated label.

Abstract: A dam has a slat disposed therein with protrusions along its sheet-engaging surface. If more than one sheet is fed from a stack to the dam, the sheets strike the slat surface and protrusions, causing the sheets to buckle and then separate from each other.

Abstract: A sheet feeding apparatus having an edge aligned system always maintains a nip between an intermittently driven pick roll and a friction or separator pad. When a top sheet of a stack is being advanced by the pick roll, a first spring exerts a first force on the friction or separator pad to enable advancement and separation of the top sheet. When the pick roll is stopped, a second spring exerts a second force substantially smaller than the first force on the friction or separator pad but sufficient to maintain the nip between the pick roll and the friction or separator pad to retard.

Abstract: A self-adjusting wrap spring clutch has a spring overlying driving and driven arbors and in engagement with each. One end of the spring is loosely connected to a control collar, which surrounds the spring and at least a portion of each of the arbors, while its other end is connected to the driven arbor. The control collar is held against rotation by a spring biased pawl engaging one of a plurality of preferably equiangularly spaced teeth on its circumference. When a solenoid is energized, the pawl is withdrawn from the tooth on the control collar and the spring tightens on the driving arbor to transmit torque to the driven arbor from the driving arbor. The pawl rides on a cam surface on a gear hub, which rotates whenever the driven arbor rotates, until the pawl falls into an opening or low dwell in the cam surface so that the pawl can engage one of the teeth on the control collar.

Abstract: A sheet support tray has its bottom support wall formed with a lower level planar portion and an upper level planar portion. The upper level planar portion extends from a reference edge a distance so that only one of two feed rollers can engage its sheet support surface, which has a last sheet restraint pad on it for engaging the one feed roller after the last sheet has been fed. The other feed roller cannot engage a last sheet restraint pad on the lower level planar portion so that narrow width sheets can be fed without skewing by the one feed roller.
