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.
Claims20
An inkjet printer, comprising:
- a substrate support;
- a calibration module comprising:
- a stage member with a vacuum extension that comprises a flat vacuum surface, an internal plenum, and openings in the vacuum surface that provide fluid flow from the surface to the internal plenum;
- and
- a tensioner comprising a metal strip;
- 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.
