Printing system for accommodating various substrate thicknesses

Abstract

A system for printing images on a substrate includes a multiplicity of print heads mounted in a carriage and positioned a distance from the substrate. A sensor detects the thickness of the substrate as the substrate moves through the system, and a control system receives the substrate thickness information detected by the sensor and transmits signals to a motor coupled to the carriage. These signals instruct the motor to adjust the position of the carriage to maintain a desired gap between the print heads and the substrate.
