Abstract: In example implementations, an apparatus and method are provided. The apparatus includes a movable carriage, an energy source coupled to the movable carriage and a plurality of shutters coupled to the movable carriage. In one example, the plurality of shutters is coupled to the movable carriage along a length of the energy source. Each one of the plurality of shutters may be coupled to the movable carriage via respective coupling mechanism that provides a continuously variable movement of each one of the plurality of shutters.

Abstract: According to an example, an apparatus to prevent media transport jams may include an actuator to load and advance a media within a media path width. The apparatus may also include a first sensor and a second sensor to detect respective edges of the media, in which the first sensor and the second sensor may be positioned outside of a media action area and on opposite sides of the media path width. The apparatus may further include a controller to prevent the actuator from advancing the media along the media path in response to a detection of one or both of the first edge of the media by the first sensor and the second edge of the media by the second sensor.

Abstract: According to examples, an apparatus may include a chassis having an interior region and a first printing fluid reservoir arranged within the interior region of the chassis. The chassis may fix the first printing fluid reservoir relative to a second printing fluid reservoir. The apparatus may also include a bottle seat that may define a charging port in fluidic communication to the first printing fluid reservoir to convey refill printing fluid received at the charging port to the first printing fluid reservoir. A fluidic interface may be arranged on the chassis and fluidically coupled to the first printing fluid reservoir to convey the printing fluid outside the chassis to a print head.

Abstract: A printing device has a reservoir of colorant that is fillable from an external colorant supply temporarily connectable to the printing device. A selectable fill mode of the reservoir is enabled from a number of fill modes. The fill modes include a restricted fill mode in which the reservoir is filled from the external colorant supply responsive to determining that the external colorant supply can be emptied into the reservoir. The fill modes include an unrestricted fill mode in which the reservoir is filled from the external supply regardless of whether the external colorant supply can or cannot emptied into the reservoir. The printing device, responsive to temporary connection of the external colorant supply, controls filling of the reservoir from the external colorant supply in accordance with the selected fill mode.

Abstract: An extraction pump of a printing device fluidically connected to a reservoir of the printing device is set to a specified rotational velocity. A pulse-width modulation (PWM) value of the extraction pump correspondingly increases until the extraction pump rotates at the specified rotational velocity. While the power of the extraction pump is monitored, a power of a supply pump of the printing device fluidically connected between the extraction pump and the reservoir is continually increased; the power of the extraction pump correspondingly decreases to maintain rotation of the extraction pump at the specified rotational velocity. Responsive to the power of the extraction pump decreasing to a characterized value for the specified rotational velocity, the power of the supply pump ceases being increased.

Abstract: An example of a device (100) may include a valve body (108). The device may include a printing substance transfer window (122) through the valve body (108). The device (100) may include a printing substance dispensing nozzle (110) rotatable within the valve body (108) between a first orientation with an orifice of the printing substance dispensing nozzle (110) facing an internal face of the valve body (108) and a second orientation with the orifice (126) of the printing substance dispensing nozzle (110) facing the printing substance transfer window (122). The device (100) may include a dispensing-side gasket material (132) slideable against the internal face of the valve body (108) when rotating the printing substance dispensing nozzle (110) between the first orientation and the second orientation.

Abstract: Examples of the present disclosure relate to a container. The container has a chamber for storing build material for a three-dimensional printing system. The container comprises an opening co-axial with the chamber for coupling to the three-dimensional printing system. The container is configured such that rotation of the chamber in a first direction conveys build material in the chamber to the three-dimensional printing system and rotation of the chamber in a second direction conveys the build material away from the three-dimensional printing system.
