Abstract
Examples described herein include methods and devices for systems that include a conveyor belt comprising an exterior surface and an interior surface, an embedded optical sensor disposed proximate to the interior surface of the conveyor belt to optically detect movement of the conveyor belt, and a driver to move the conveyor belt based on the detected movement of the conveyor belt.
Claims13
A system comprising:
- a conveyor belt comprising an exterior surface and an interior surface;
- an embedded optical sensor disposed proximate to the interior surface of the conveyor belt to optically detect movement of the conveyor belt;
- and
- a driver to move the conveyor belt based on the optically detected movement of the conveyor belt,
- wherein the conveyor belt comprises a triangular ridge formed in the interior surface, the ridge comprising markings detectable by the embedded optical sensor to optically detect the movement of the conveyor belt.
2 more elements
A method comprising:
- activating a conveyor belt driver to move a conveyor belt;
- detecting movement of an interior surface of the conveyor belt optically using markings in a triangular ridge formed in the interior surface of the conveyor belt;
- and
- applying a correction to the conveyor belt driver based on the optically detected movement of the interior surface of the conveyor belt.
1 more element
A printer comprising:
- a print engine to apply printing material to a print media;
- a media handler to move the print media relative to the print engine and comprising:
- a conveyor belt comprising an exterior surface and an interior surface;
- a driver to move the conveyor belt;
- and
- a vacuum handler to hold the print media against the conveyor belt;
- an embedded optical sensor disposed proximate to the interior surface of the conveyor belt to optically detect movement of the conveyor belt;
- and
- a print controller to control the driver or the print engine based on the detected movement of the conveyor belt,
- wherein the conveyor belt comprises a triangular ridge formed in the interior surface, the ridge comprising markings detectable by the embedded optical sensor to optically detect the movement of the conveyor belt.
