For Color Photo Printers  
(300DPI ; dots / inch)  
NF3004-VC20A  
The NF3004-VC20 Series are suitable for small photo printers which can make direct print out from digital still cameras  
and mobile phones. ROHM’s energy saving technology 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) NF3004-VC20 is drivable with batteries, thanks to it’s low energy consumption.  
2) NF3004-VC20 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.
