Abstract: In some examples, the disclosure describes a device that includes a first media tray positioned at a media input of a pick and separation mechanism, a second media tray positioned at the media input of the pick and separation mechanism, a media scan guide to position a sheet of print media at the media input of the pick and separation mechanism, a shared media path comprising a turn roller to receive the sheet of print media from the pick and separation mechanism from a first direction and provide the sheet of print media to a print zone in a second direction, and an output zone to receive the sheet of print media from the shared media path.

Abstract: An example support structure assembly is described as including a brace, a media guide, and a compression member. An example brace includes a structure defining a mount area on a first surface of the brace and a first protrusion extending from a second surface of the brace. An example media guide includes a blade member, a hinge member, and a second protrusion extending away from the hinge member. An example compression member is coupled to the first protrusion of the brace and the second protrusion of the media guide to place a force on the media guide where a vector defines the force with a first component magnitude in a first direction towards the mount area that is greater than a second component magnitude in a second direction away from the mount area.

Abstract: An example apparatus includes a cap to seal a printhead in a printhead assembly, where the cap includes a priming port and a venting port. A vent connected to the venting port is sealed by a cam controlled vent-arm while a vacuum pump connected to the priming port applies a vacuum to prime the printhead. The vent is unsealed by the cam controlled vent-arm and the vacuum pump clears ink from the priming cap.

Abstract: An example system includes a pressure plate actuating portion. The pressure plate actuating portion includes a cam gear coupled to a cam arm and a pressure plate arranged to be driven by the cam arm as the cam arm rotates with the cam gear through a pick-up cycle, the pressure plate being biased in a first direction toward the cam arm with a pressure plate spring. The example system also includes a pressure plate release control portion, the pressure plate release control portion being arranged to transfer potential energy from the pressure plate spring in a gradual manner.

Abstract: In an example, a roller lock may include a lock to engage with a roller of a feed system, and a leadscrew to engage with the lock. The lock may include a coupling to operably engage with a complementary coupling of the roller. The leadscrew may include an advancer to engage with the lock such that the advancer may translate the lock along a longitudinal axis of the roller so that the lock may engage and disengage with the roller to intermittently prevent the roller from rotating in a forward direction.

Abstract: In one embodiment, a device for a printer includes a movable tray for supporting a print media. The tray is movable between an open position in which media may be moved on to the tray and a closed position in which media is blocked from moving on to the tray. The device also includes a rotatable media drive component for moving print media on to the tray and a movable restraint operatively connected to the tray. The restraint is movable between: a first position, corresponding to the open position of the tray, in which the restraint does not restrain the media drive component; and a second position, corresponding to the closed position of the tray, in which the restraint restrains rotation of the media drive component.

Abstract: In an implementation, an example method of indexing a media feed shaft in a media feed device includes rotating a media feed shaft and transmitting the rotation to an output gear that is remote from the media feed shaft. The method also includes sensing a feature of the rotating output gear and indexing the media feed shaft to the feature.

Abstract: In one example in accordance with the present disclosure an apparatus for attaching to a shaft using a wedge is described. The apparatus includes a disc having a longitudinal axis. At least a portion of the disc is insertable into a shaft and is expandable against an inside diameter of the shaft. The disc has a recess at the longitudinal axis. A wedge to be inserted into the recess pushes the portion of the disc that is insertable into the shaft against an inside diameter of the shaft.
