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.
zApplications
Bar code printer
Label printer
Packaging printer
ATM
Ticket printer
zFeatures
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.
