Abstract: An example apparatus includes a gear comprising a gear hub; a swing-arm rotationally engaged with the gear hub; and a spring circumferentially engaged with the gear hub and the swing-arm to apply a radial clamping force between the swing-arm and the gear hub. Torque is frictionally coupled from the gear hub to the swing-arm to lock a capped print head assembly (PHA) in a non-printing location.

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.

Abstract: An example ink tank includes an ink tank and a cap assembly attached to the ink tank with a preloaded hinge. The hinge rotates the cap assembly from a closed position to an open position when the cap assembly is unlatched. The cap assembly includes a bung to seal the ink tank during a partial rotation of the cap assembly when the cap assembly is unlatched. The ink tank also includes spring-loaded linkage connected to a valve in the ink tank. An effector extending from the cap assembly engages the spring-loaded linkage when the cap assembly is latched and disengages from the spring-loaded linkage after the cap assembly is unlatched. The spring-loaded linkage opens the valve when engaged with the effector, and closes the valve when disengaged from the effector, while the bung maintains a tank seal until the internal valve is closed.

Abstract: In one example, a printing device is described. The printing device may include a transport roller to move a print medium through the printing device, a sensor to detect a trailing edge of the print medium, a processor, and a non-transitory computer-readable medium storing instructions. In one example, the instructions, when executed by the processor, cause the processor to move the print medium toward an output of the printing device via the transport roller after a printing to the print medium, detect the trailing edge of the print medium via the sensor during a movement of the print medium via the transport roller, and hold the print medium in a position in contact with the transport roller, in response to a detection of the trailing edge of the print medium via the sensor.

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: 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.
