(perform three times life time by coefficient of abrasion wh ich is about is about 1/10 of current mass-producing coat.) 2) build in thermal high speeded heater and perform high printing 4 ips. (100mm / s) 3) available for thermal transfer printing by adopting specific partial glaze. z dimensions (unit : mm) jst b6ps-vh hirose hif3fc-20pa-2.54ds (19) 15?.3 15.3?.3 17.8?.2 7.3?.3 80?.3 3-m3(effective depth 3) 95?.3 (20.8) 25?.5 (effective depth 3) 3h10 length 4 14.208?.2 (effective depth 3) 3h10 40 0.3 118 max. 20 max.5.5 dot #1 dot #1280 (4.792) (3) max.36 max.45 #1 #6 #20 #19 #2 #1 max.10 (5) 6.1?.4 type of printhead 108.416(effetive print width)
