Features 1) ROHM unique “STEP FREE” structure contributes to better anti-corrosion characteristics, less scratch break down, and better heat efficiency. 2) Thermal head contacts with the media by angle at the print, so that good print quality can be obtained for the thick media. 3) It has good anti-ESD characteristic by applying hard, conductive layer as the heat element protective coating. 4) Mounting space can be minimized, which contributes to the downsizing of the printer.
