Near edge thermal Printhead
SJ3002-EC60A
A near-edge structure and Real Flat glazing technology make it possible to use the NE printhead for straight path printing.
This thermal printhead is made for card and heavy stock paper applications. Because the thickness and quality of the
print media matter little, the NE is suitable for a wide range of applications.
zApplications
Card printers
Ticket printers
zFeatures
1) ROHM new technology “STEP FREE” structure will provide, high corrosion resistance, better resistance against
scratching damage, high efficiency.
2) The use of ROHM’s proprietary G-form structure ensures a compact form and light weight. Naturally, it also means that
the NE can be used without a heat sink. This gives engineers greater freedom when designing the printer mechanics.
3) Owing to the excellent smoothness of the surface of the print face, it is possible to achieve excellent print quality even
when printing on hard card.
4) Inclined toward the printing surface to provide excellent printing quality even for cards and thick paper.
