SF3004-EC10A
The SF3004-EC10 Series are suita ble for smal l photo printers whic h can ma ke direct p rint out from digital still cam eras
and mobile phones. ROHM’ s techno logy based on “S tep-free ” structure ena bles batte ry drive, an d high resoluti on printing
quality .
zApplications
Home printers
Mobile Photo printers
Photo kiosk terminals
“Print club” (color photo printer) terminals
zFeatu res
1) SF3004-EC10 is drivable with batterie s, thanks to it’ s low energy consump tion.
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.
