Abstract
A printing apparatus comprises a jetting assembly including a plurality of nozzles for ejecting droplets on a substrate moving relative to the jetting assembly, a mechanism for increasing the displacement of the jetting assembly relative to the substrate, and a sensor configured to activate the mechanism for increasing the displacement of the jetting assembly upon detecting a predetermined dimension of the substrate surface relative to the jetting assembly.
Claims15
A printing apparatus comprising:
- a jetting assembly including a plurality of nozzles for ejecting droplets on a substrate moving relative to the jetting assembly;
- a mechanism for changing the displacement of the jetting assembly relative to the substrate;
- and
- a sensor configured to activate the mechanism for changing the displacement of the jetting assembly upon detecting a predetermined dimension of the substrate surface relative to the jetting assembly.

A method of printing on a substrate comprising:
- positioning a jetting assembly above a conveyer;
- placing the substrate on the conveyer;
- detecting a portion of the substrate extending beyond a pre-determined distance from the conveyer;
- and
- raising the jetting assembly in response to detecting a portion of the substrate extending beyond a pre-determined distance from the conveyor.
