ABSTRACT:
An apparatus, system and method for detecting ink errors in optical disk printing are provided. The apparatus, system and method include a sensor mount structure and a plurality of optical sensors mounted on the mount structure and in registration with a print table. A controller selectively activates the optical sensors in accordance with a relative motion between the optical sensors and the printing station such that the optical sensors each scan an assigned region of the print table to detect ink outside of an area where an object to be printed is placed.
