Abstract: Example implementations relate to initiation of a shortage model in a printing device. For example, initiation of a shortage model may include guidance of a page of print media through a printing device by a feedshaft and an upper paper guide, where the page of print media is held by a media control surface. A shortage model may be initiated based on an amount of data to be printed. An ink nozzle may be turned off based on the initiated shortage model.

Abstract: In one example in accordance with the present disclosure, an additive manufacturing build unit is described. The additive manufacturing build unit includes a vibrating bed on which a volume of build material is to be disposed. The bed is to vibrate to remove excess build material. A non-vibrating frame of the build unit supports the vibrating bed. The build unit also includes a bed-frame interface to: couple the vibrating bed to the non-vibrating bed frame, and isolate vibrations to the vibrating bed. A flexible seal of the build unit is disposed between the vibrating bed and non-vibrating frame. The flexible seal prevents build material from contaminating an additive manufacturing system in which the additive manufacturing build unit is disposed and allows relative motion between the vibrating bed and the non-vibrating frame.

Abstract: A selectable drive printing device includes a drive selector system to select between driving a print drive system and driving a scan drive system based at least partially on a position of a selector swing arm of the drive selector system. The selectable drive printing device includes a shifter to selectively shift the drive selector system between a scanning system drive position of the selector swing arm and a printing system drive position of the selector swing arm.

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.
