ROHM SE3004-DC70A Technical data
SE3004-DC70A
Printhead Under development
High speed thermal printhead
(with thermal historical control)
SE3004-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
Barcode printer
Label printer
Packaging printer
Ticket printer
Scale printer
ATM
zFeatures
1) ROHM new technology “STEP FREE” structure will provide, high corrosion resistance, better resistance against
scratching damage, high ef ficiency.
2) High-hardness protect cote type “W-coat” is employed with 150km abrasion life-time.
3) A built in history-control functionary, high-speed printing up to 300mm / s can be achieved at 300dpi with clear print
image.
