| Tentative Printheads SH3002-DC90A Near edge thermal printhead (300 dots / inch) SH3002-DC90A SH-DC90 series was developed with two key structures step-free and near edge for the packaging printer market which requires high speed continuous printing. It is suitable for printers in factory line where high speed 24 hours continuous printing is required. Applications Bar code printer Label printer Packaging printer ATM Ticket printer Features 1) ROHM new technology "STEP FREE" structure will provide, high corrosion resistance, better resistance against scratching damage, high efficiency. 2) High dot reproducibility with step-free structure. 3) Head inclination by near-edge structure, applicable to the large-size platen. Resin type thermal-transfer ink-ribbon can be used. 3) High-hardness protect cote type "W-coat" is employed with 150km abrasion life-time. 4) Even without history-control, high-speed printing more than 200mm / s can be achieved at 300dpi with clear print image. With history-control, 300mm / s printing is also possible at 300dpi.
