NF2004-VA20A
The NF2004-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
!
Bar code label printers
Ticket printers
General purpose compact printers
Features
!
1) Standard glazed components to accommodate thick paper.
2) High speed clock to facilitate external heat history control.
3) Using a hard conductive film as a protective film on the heating element offers excellent resistance to electrostatic
damage.
4) Compatible with the NF3004-VA20A (300dpi) in mechanical specifications, to facilitate the making of a series of
printers.
