Abstract
Method and tools for sensing pen-to-reference space (PRS) are disclosed. Example removable pen-to-reference space (PRS) sensing tools for a printer comprise proximity sensors and a body. The body has a printer mounting portion, corresponding to a printhead mounting socket of the printer, and a sensor portion, hosting the proximity sensor.
Claims15
A removable pen-to-reference space (PRS) sensing tool for a printer, comprising:
- a proximity sensor;
- and
- a body having
- a printer mounting portion, corresponding to a printhead mounting socket of the printer, and
- a sensor portion, hosting the proximity sensor.
2 more elements
A printing system, comprising:
- A printbar with a printhead socket;
- A platen below the printbar;
- A controller.
- wherein a distance sensor may be coupled to the printhead socket to measure distance between distance sensor and the platen being the controller to receive distance values measured and to adjust the distance between the printbar and the platen.
1 more element
Method of measuring PRS distance, comprising:
- placing an inductive sensor tool in a printhead socket;
- measuring distance between the inductive sensor tool and a metallic target associated to a platen;
- adjusting distance between printbar and platen in response to distance measured.
