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.
