SF3004-EC10A printheads 1/4 for color photo printers (300dpi ; dots / inch) SF3004-EC10A the sf3004-ec10 series are suitable for small photo printers which can make direct print out from digital still cameras and mobile phones. rohm?s technology based on ?step-free? structure enables battery drive, and high resolution printing quality. z applications home printers mobile photo printers photo kiosk terminals ?print club? (color photo printer) terminals z features 1) sf3004-ec10 is drivable with batteries, thanks to it?s low energy consumption. 2) sf3004-ec10 enables full color printing by keeping the adjacent resistance variation less than 1.5%. 3) employing of the driver ic capable of high-speed data transfer at 3.3 circuit supply voltage makes the gradation printing control easier. 4) high dot reproducibility with step-free structure. z external dimensions (unit : mm) dot #1 114.2 0.2 108.16 (3.02) 10 (5.835) max.14 dot #1280 cl
