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.

First claim

What is claimed is:

1 . An inkjet printer, comprising:
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.

2 . The inkjet printer of claim 1 , wherein the stage member comprises a vacuum extension.

3 . The inkjet printer of claim 2 , wherein the vacuum extension comprises a porous body.

4 . The inkjet printer of claim 3 , wherein the vacuum extension further comprises a holder and the porous body is embedded in the holder.

5 . The inkjet printer of claim 4 , wherein the calibration module is configured to receive a test substrate and to position the test substrate between the vacuum extension and the print assembly.

6 . The inkjet printer of claim 5 , wherein the calibration module is configured to receive a removable test substrate assembly containing the test substrate and the calibration module further comprises a lifter to position the test substrate for installation of the removable test substrate assembly.

7 . The inkjet printer of claim 5 , wherein the test substrate assembly is a roll-to-roll assembly.

8 . The inkjet printer of claim 1 , wherein the test module further comprises a tensioning member for engaging with a test substrate.

9 . The inkjet printer of claim 1 , wherein the tensioning member is a passive tensioning member.

10 . An inkjet printer, comprising:
a substrate support; a calibration module disposed adjacent to the substrate support and configured to receive a removable cassette housing a test substrate, the calibration module 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.

11 . The inkjet printer of claim 10 , wherein the stage member comprises a vacuum extension.

12 . The inkjet printer of claim 11 , wherein the vacuum extension comprises a porous body.

13 . The inkjet printer of claim 12 , wherein the vacuum extension further comprises a holder, and the porous body is embedded in the holder.

14 . The inkjet printer of claim 13 , wherein the calibration imaging device and the printhead are independently movable.

15 . The inkjet printer of claim 14 , wherein the calibration module further comprises a tensioning member for engaging with the test substrate.

16 . The inkjet printer of claim 15 , wherein the tensioning member is a passive tensioning member.

17 . An inkjet printer, comprising:
a substrate support; a calibration module disposed adjacent to the substrate support and comprising a stage member that has a vacuum extension comprising a porous body; 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, wherein the printhead and the calibration imaging device are independently movable.

18 . The inkjet printer of claim 17 , wherein the porous body is ceramic.

19 . The inkjet printer of claim 17 , wherein the vacuum extension further comprises a holder for the porous body.

20 . The inkjet printer of claim 17 , wherein the calibration module is configured to receive a removable test substrate assembly containing a test substrate.

21 . The inkjet printer of claim 17 , wherein the calibration module comprises a linear positioner.
