Tentative SE3004-DC90A
Printhead Under development
High speed thermal printhead
(300 dots / inch)
SE3004-DC90A
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*-DC 90A 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
Barcode printers
Label printers
Packaging printers
ATM
Ticket printers
Scale printers
zFeatures
1) ROHM new technology “STEP FREE” structure will provide, high corrosion resistance, better resistance against
scratching damage, high ef ficiency.
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 heat ing element offers excellent resistance to ele ctrostatic
damage.
