Abstract
An inkjet printer is described. The inkjet printer has a gas cushion substrate support having a metal support surface; a print assembly with a dispenser having ejection nozzles facing the support surface; a gas source fluidly coupled to the gas cushion substrate support by a gas conduit; and a thermal control system coupled to the gas conduit.
Claims20
A method, comprising:
- using a gas cushion substrate support to support a substrate, the gas cushion substrate support comprising a metal support surface and a plurality of holes formed through the metal support surface;
- flowing a gas through a gas conduit and through the plurality of holes to form a gas cushion between the substrate and the metal support surface to support the substrate;
- depositing a print material on the substrate while the substrate is supported by the gas cushion;
- and
- thermally controlling the substrate by adjusting a flowrate of the gas, adjusting a temperature of the gas using a thermal control system coupled to the gas conduit, or both.

A method, comprising:
- using a gas cushion substrate support to support a substrate, the gas cushion substrate support comprising a metal support surface and a plurality of holes formed through the metal support surface;
- flowing a gas through a gas conduit and through the plurality of holes to form a gas cushion between the substrate and the metal support surface to support the substrate;
- exhausting gas from the gas cushion through a plurality of gas escape passages formed through the gas cushion substrate support;
- depositing a print material on the substrate while the substrate is supported by the gas cushion;
- and
- thermally controlling the substrate by adjusting a flowrate of the gas, adjusting a temperature of the gas using a thermal control system coupled to the gas conduit, or both.

A method, comprising:
- using a gas cushion substrate support to support a substrate, the gas cushion substrate support comprising a metal top member, a support plate, and a plurality of holes formed through the metal support member and the support plate;
- flowing a gas through a gas conduit and through the plurality of holes to form a gas cushion between the substrate and the metal support surface to support the substrate;
- exhausting gas from the gas cushion through a plurality of gas escape passages formed through the top member and the support plate;
- depositing a print material on the substrate while the substrate is supported by the gas cushion;
- controlling the gas cushion by controlling a flowrate of the gas;
- and
- thermally controlling the substrate by adjusting a temperature of the gas using a thermal control system coupled to the gas conduit, the thermal control system comprising a thermal unit that circulates and controls a thermal medium and a heat exchanger that thermally couples the thermal medium with the gas.
