Abstract
An inkjet printer is disclosed that has a substrate support; a calibration module disposed adjacent to the substrate support and comprising a stage member; and a print assembly disposed across the substrate support, the print assembly comprising a printhead and a calibration imaging device positionable to face the stage member.
Claims18
An inkjet printer, comprising:
- a substrate support;
- a calibration module disposed adjacent to the substrate support and comprising a stage member with a vacuum extension that provides a chucking force for a test substrate that is greater at peripheral areas than central areas the vacuum extension comprising a vacuum surface, an internal plenum, and openings in the vacuum surface that provide fluid flow from the surface to the internal plenum;
- and
- a print assembly disposed across the substrate support, the print assembly comprising a printhead and a calibration imaging device positionable to face the stage member.

An inkjet printer, comprising:
- a substrate support;
- a calibration module disposed adjacent to the substrate support and comprising a stage member with a vacuum extension that provides a chucking force for a test substrate that is greater at peripheral areas than central areas the vacuum extension comprising a vacuum surface in fluid communication with an internal plenum;
- and
- a print assembly disposed across the substrate support, the print assembly comprising a printhead and a calibration imaging device movable independently from the printhead and positionable to face the stage member.

An inkjet printer, comprising:
- a substrate support;
- a calibration module disposed adjacent to the substrate support and comprising a stage member with a vacuum extension having a flat vacuum surface that provides a chucking force for a test substrate that is greater at peripheral areas than central areas, wherein the flat vacuum surface engages with a test substrate to provide a deviation from flatness of the substrate surface that is less than about 5 μm;
- and
- a print assembly disposed across the substrate support, the print assembly comprising a printhead and a calibration imaging device movable independently from the printhead and positionable to face the stage member.
