Abstract: In an example of the disclosure, service rotation of a drum along a longitudinal axis of the drum is caused. The service rotation is to apply a centrifugal force upon a liquid held by the drum. The centrifugal force pushes gas bubbles in the drum away from a curved surface of the drum and towards the longitudinal drum axis. The gas bubbles evacuate from the drum via an outlet tube positioned adjacent to the longitudinal drum axis. A production rotation of the drum is caused after the service rotation.

Abstract: In one example, a conduit for returning liquid printing material to a liquid printing material storage tank in a printer comprises a first tubular section and a second section for receiving a flow of liquid printing material from the first tubular section. The second section is arranged to convert the flow of liquid material received from the first section into a falling liquid curtain of liquid printing material that is output from the second section to flow to the liquid printing material tank.

Abstract: In certain examples, a printing system comprises: a depositing system to deposit printing fluid on a print medium; a reservoir; and a displacement pump to move printing fluid to the depositing system from the reservoir. The displacement pump comprises: a pump body defining a chamber, an inlet to fluidly connect the chamber to the reservoir, and an outlet to fluidly connect the chamber to the depositing system; and a displacement member movable relative to the pump body; the displacement member having an outer surface and comprising a cavity located in a portion of the outer surface disposed in the chamber. In use, the displacement member is movable to close the inlet and to force printing fluid in the chamber through the outlet to the depositing system.

Abstract: Offset print apparatus comprises a blanket arranged in a closed loop around a plurality of rollers. Each of the plurality of rollers is rotatable about a respective roller axis to support and convey the blanket around the closed loop. The plurality of rollers comprises: a primary steering roller rotatable about a primary roller axis and being pivotable about a primary steering axis perpendicular to the primary roller axis; and a secondary steering roller rotatable about a secondary roller axis and being pivotable about a secondary steering axis perpendicular to the secondary roller axis. The primary and secondary steering rollers are each independently pivotable. The offset print apparatus further comprises an actuator to actuate pivoting of the primary steering roller and the secondary steering roller.

Abstract: An example printing fluid apparatus, for a printing system, comprises a printing fluid reservoir to store printing fluid for use in a print job and a printing fluid channel to route printing fluid from the reservoir to the reservoir and to route printing fluid from a printing station of the printing system to the reservoir. The fluid channel comprises a port to introduce printing fluid from a printing fluid cartridge into the fluid channel such that the introduced printing fluid from the printing fluid cartridge at least partially mixes with printing fluid in the fluid channel.
