Improvement of the Printing Position Accuracy for an Impact-dot-printer to Print on the Continuous Multi-layer Paper. The impact printers used with computers can use continuous multi-layer paper for printout. But when the paper is fed improperly, the printing position on the top sheet of multi-layer paper slips off from the position of tile bottom sheet. A study was made to improve the function of the paper feeding mechanism. As the paper feeding function, the input was the indicated amount of paper feeding and the output was the actual fed amount of paper. For the noise factor, the positions of top and bottom layers was considered. Zero Point Proportional equation was used for SN ratio calculations. A gain of 3.5 db was estimated and 4.0 db was confirmed.
