Abstract: Examples relate to a method to recirculate print agent in a printing system. The method comprises detecting a recirculation device comprising a check valve and detecting a printhead connected in parallel to the detected recirculation device. The method further comprises selecting a printhead circulation mode to circulate print agent through the detected printhead and selecting a recirculation device circulation mode to circulate print agent through the detected recirculation device.

Abstract: According to an example, a printhead storage device comprises a printhead pocket to receive a printhead, a receptacle with an interior chamber wherein printing fluid is provided, and a fluid interconnect device comprising a fluid path with the interior chamber. Upon insertion of a printhead to the pocket, the fluid interconnect device is connected to the printhead, thereby providing a fluid connection between the printhead and the interior chamber and wherein the printhead is not operable when inserted in the printhead pocket.

Abstract: Aspects of the disclosure provide an electronic device comprising a controller. The controller to determine a volume of print fluid in a first tank of the electronic device, monitor current printing conditions of the electronic device disposing print fluid on a substrate, determine, based on the volume of print fluid and the current printing conditions, whether an adverse printing condition exists, responsive to the volume of print fluid being less than a threshold and the adverse printing condition not existing, control a pump to refill the first tank from a second tank at a flow rate determined at least partially according to the determined volume, and responsive to the volume of print fluid being less than the threshold and the adverse printing condition existing, control the pump to refill the first tank from the second tank at a default flow rate determined independent of the determined volume.

Abstract: A media stacker (100) comprises a stacking platform (102), a feed mechanism (104), a media arresting mechanism (106) and a controller (108). The feed mechanism conveys media sheets for dispensing onto the stacking platform, wherein the media sheets are dispensed onto the stacking platform with a momentum imparted by the feed mechanism. The media arresting mechanism reduces the momentum of media sheets. The controller determines that a trailing edge of a media sheet is to be dispensed onto the stacking platform, and further control the media arresting apparatus to reduce the momentum of the media sheet in response to the determination.

Abstract: Stacker device to stack sheets of print media. The stacker device comprises a tray to stack the sheets. The tray comprises an M-shaped tray section to apply an M-shaped profile to a sheet along a direction perpendicular to the sheet's advance direction to reduce curling. The stacker device further comprises a roof. The roof comprises at least one adjustable roof portion to limit a height of a curl of the sheet.
