Research On And Design Of Plot Controller Of Color Inkjet Plotter

This paper presents the design of plot controller of a wide format color inkjet plotter through the analysis of its principle and construction. Instead of using ASIC this design is a distributing microcomputer system which consists of general SCM whose functions are appropriate to the design.The paper gives a detailed introduction to the direct current PWM servo driver of print-head carriage, the high precise position technology of print-head using the linear grid-shaped capacitive position transducer and the algorithm and programming of controller software.The design has some advantages of simple construction, convenient debugging, low production cost, high reliability, and high performance. The research and practice in this paper possess certain practical significance and referential value in promoting the development of inkjet plot technology, especially of the industrialization and independence of inkjet plotter.
