Printer calibration module
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.
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, wherein the stage member comprises a vacuum extension.
2. The inkjet printer of claim 1 , wherein the vacuum extension comprises a porous body.
3. The inkjet printer of claim 2 , wherein the vacuum extension further comprises a holder and the porous body is embedded in the holder.
4. The inkjet printer of claim 3 , 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.
5. The inkjet printer of claim 4 , 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.
6. The inkjet printer of claim 4 , wherein the test substrate assembly is a roll-to-roll assembly.
7. 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, wherein the test module further comprises a tensioning member for engaging with a test substrate.
8. The inkjet printer of claim 7 , wherein the tensioning member is a passive tensioning member.
9. 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, wherein the stage member comprises a vacuum extension.
10. The inkjet printer of claim 9 , wherein the vacuum extension comprises a porous body.
11. The inkjet printer of claim 10 , wherein the vacuum extension further comprises a holder, and the porous body is embedded in the holder.
12. The inkjet printer of claim 11 , wherein the calibration imaging device and the printhead are independently movable.
13. The inkjet printer of claim 12 , wherein the calibration module further comprises a tensioning member for engaging with the test substrate.
14. The inkjet printer of claim 13 , wherein the tensioning member is a passive tensioning member.
15. 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.
16. The inkjet printer of claim 15 , wherein the porous body is ceramic.
17. The inkjet printer of claim 15 , wherein the vacuum extension further comprises a holder for the porous body.
18. The inkjet printer of claim 15 , wherein the calibration module is configured to receive a removable test substrate assembly containing a test substrate.
19. The inkjet printer of claim 15 , wherein the calibration module comprises a linear positioner.
