Hight Speed Thermal Printhead
(300DPI ; dots / inch)
NF3004-VA20A
The NF3004-VA20A is a flat thin film thermal printhead that supports medium speed and high speed printing, suited
for general purpose compact printers as well as label printers.
!Applications
High definition bar code label printers
High definition ticket printers
General purpose compact printers
!Features
1) High definition of 300 dots / inch.
2) Standard glazed components to accommodate thick paper.
3) High speed clock to facilitate external heat history control.
4) Using a hard conductive film as a protective film on the heating element offers excellent resistance to electrostatic
damage.
5) Compatible with the NF2004-VA20A (8dots / mm) in mechanical specifications, to facilitate the making of a series of
printers.
