Hight Speed Thermal Printhead
(8dots / mm)
SE2003-DC94A
High speed, high quality, and high durability are achieved by using step free structure with high performance partial glaze
and highly conductive overcoat layer. SE200*-DC94A 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).
Implementation of ROHM Unique technology, Anti Sticking Treatment, reduces sticking problems (print skip at media
feed direction) under the tough print conditions at low print speed, using label media with over coated.
zApplications
Bar code label printers
Ticket printers
General purpose compact printers
zFeatures
1) Anti Sticking Treatment reduces sticking problems and achieves high print quality at any environmental conditions.
2) ROHM new technology “STEP FREE” structure will provide, high corrosion resistance, better resistance against
scratching damage, high efficiency.
3) Standard glazed components to accommodate thick paper.
4) Using a hard conductive film as a protective film on the heating element offers excellent resistance to electrostatic
damage.
5) Compatible with the SE3003-DC90A 300dpi in mechanical specifications, to facilitate the making of a series of
printers.
