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.
External dimensions
!
Note: No heat history control function inside the thermal printhead. External heat history control is required for high speed printing.
