PRINTHEAD POSITIONING SYSTEM AND CONTROL

摘要

A printhead positioning system is provided wherein the positioning of the shuttles is done using hybrid motor drive with a high-resolution short stroke motor system mounted on a low-resolution long stroke motor system. By using an embodiment with the combination of a high resolution linear motor of which the stator is mounted on a low resolution long stroke belt drive. High accuracy over a large distance can be attained. This allows for cheaper big size high accuracy positioning systems.
