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.
zApplications
Home printers
Mobile Photo printers
Photo kiosk terminals
“Print club” (color photo printer) terminals
zFeatures
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.
