Announced in 1981, this was Mitsubishi Electric's first online kanji (Chinese character) printer. It employed the OFT (Optical Fiber Tube) system used in offline printers. The M8310 had a printing speed of 2,440LPM (line/min) at 6LPI (line/inch). Both 9 point (30×30dot) and 12 point (40×40dot) character sizes could be used, and 12-point-character patterns were automatically synthesized from 9-point-character patterns. This printer also had overlay printing and copy functions.
