Printheads Under development
High speed thermal printhead
(with thermal historical control)
SE3002-DC70A
High speed, high quality, and high durability are achieved by using step free structure with high performance partial glaze
and highly conductive overcoat la yer. SE300*-DC70A series are lined up which can accommodate with all types of
barcode labeling printers from Direct to Thermal Transfer, normal to high speed (over 300mm/s).
zApplications
Bar code printer
Label printer
Packaging printer
ATM
Ticket printer
zFeatures
