Abstract: An articulated flag member arrangement detects bi-directional passage of an object. In embodiments, the articulated flag member arrangement comprises a first flag member and a second flag member wherein the first and second flag members interact with each other to detect bi-directional passage of an object, for example, using the same sensor.

Abstract: An articulated flag body member permitting bi-directional passage of an object. The articulated flag body member has a flag body pivotably connected to a flag foot. As rotation of the flag foot occurs in one direction, the flag body rotates by engagement of a recess of the flag foot with a stop member extending along a projecting leg of the flag body. As the flag body rotates, a notch at the upper portion of the flag body changes positions such that light, or other signals, may no longer pass through the notch. Thus, positional indication of an object detected by rotation of the flag body. As rotation of the flag foot occurs in an opposite direction, an object may be extricated or removed.

Abstract: A printer for generating an image on a media sheet has a printer body with a media path extending from a media supply in a downstream direction to a media exit. An output tray and a media ejection mechanism are connected to the printer body adjacent the media exit. The ejection mechanism has a number of drive roller pairs, each of which includes a first roller and a second roller contacting each other at a nip defining a nip plane. The first rollers of the respective roller pairs are coaxial with each other, and the second rollers of the respective roller pairs are coaxial with each other. The nips of the drive roller pairs occupy a common plane, and the drive roller pairs are spaced apart from each other to define a gap. The ejection mechanism includes at least one corrugation roller positioned in the gap, rotatable on a corrugation roller axis, and having a curved surface portion displaced from the nip plane.

Abstract: A media sheet handling system and a method of duplex printing are disclosed wherein a media sheet is imaged with a phase change ink on both sides of the media sheet without smudging or remelting the images and the media sheet is partially exited from the printer into a media output tray and then is drawn back into the printer along a duplex path of travel that automatically reverses the media sheet so that the trailing edge becomes the leading edge during the imaging of the second side of the media sheet. The stiffness of the media sheet facilitates the media sheet moving above and beyond a stationary media path diverter prior to reversing its direction of travel along and passing along the duplex path of travel back to the imaging station.
