Abstract
In an example, a media conveyor includes a media support platform having a suction hole, and a valve to selectively close the suction hole. A valve actuator to actuate the valve includes an air tube having an air inlet and a seal to selectively seal the air inlet.
Claims15
A media conveyor comprising:
- a media support platform comprising a suction hole;
- a valve to selectively close the suction hole;
- and
- a valve actuator to actuate the valve and comprising an air tube, the air tube comprising an air inlet, and a seal to selectively seal the air inlet.
1 more element
A media handling apparatus comprising:
- a media support platform comprising a plurality of suction holes and, in association with a first suction hole of the suction holes, a first valve to selectively close the first suction hole, the first valve comprising a diaphragm having a position which is responsive to a pressure differential;
- a valve actuator comprising an air tube having a selectively sealable air inlet, the valve actuator being to selectively actuate the first valve;
- a negative pressure source to cause suction of air through the first suction hole when the first suction hole is open;
- and
- processing circuitry to determine, based on an attribute of a media being handled by the media handling apparatus, if the first suction hole should be open or closed and to control the valve actuator according to the determination.
2 more elements
A method comprising:
- receiving, on a media support platform of a media handling apparatus, a media sheet;
- generating a negative pressure;
- generating an actuation signal to selectively seal an inlet of an air tube and thereby cause a pressure operated valve to communicate the negative pressure to the media sheet as an applied suction;
- and
- conveying the media sheet on the media support platform under the applied suction.
