Abstract: There is disclosed a sheet media processing machine comprising a media inlet to receive sheet media along a feed direction from a first side of the machine and a media outlet to discharge sheet media along a discharge direction towards the first side of the machine. There is a feed mechanism to convey sheet media from the media inlet to the media outlet, and a re-feed prevention element disposed upstream of the media inlet with respect to the feed direction to inhibit recirculation of discharged sheet media along an external recirculation path between the media outlet and the media inlet. The re-feed prevention element is exposed to contact with sheet media and comprises an elastomer. There is also disclosed a feed guide comprising a re-feed prevention element, and a method in which such a feed guide is installed on a sheet media processing machine.

Abstract: A spittoon system for a printing mechanism includes a reservoir elongated in a longitudinal direction and having a bottom part. The reservoir receives printing fluid residue spit from a print-head onto a first zone of the reservoir. The spittoon system further includes a cleaning element arranged inside the reservoir to transfer, by sliding along the longitudinal direction of the reservoir, the received printing fluid residue from the first zone to a second zone. The second zone includes a drain outlet to drain the printing fluid residue from the reservoir.

Abstract: A spittoon beam system and a printer that includes a spittoon beam system. The system has a spittoon beam spanning and movably mounted to spaced spaced parallel tracks. The spittoon beam is driven along the tracks by a first motor and a second motor coupled to respective ends of the spittoon beam. A first motor driver is coupled to the first motor and a second motor driver coupled the second motor. The system is configured so that the first motor driver controls an output shaft speed of the first motor independently of the second motor driver, and the second motor driver controls an output shaft speed of the second motor independently of the first motor driver.
