High speed thermal printhead

(300 dots / inch)

NF3002-VA30A

NF-VA30 series are the thermal printheads developed for high-speed / high-resolution printing for the market of bar-code

printer & scale-printer, based on “step-free” structure.

These printheads realize ultra-highspeed printing with long life & high reliability.

Applications

Bar code printer

Label printer

Packaging printer

ATM

Ticket printer

Features

1) High dot reproducibility with step-free structure.

2) High-hardness protect cote type “W-coat” is employed with 150km abrasion life-time.

3) Even without history-control, high-speed printing more than 300mm / s can be achieved at 300dpi with clear print

image. With history-control, 500mm / s printing is also possible at 300dpi.
