Printheads
Hight Speed Thermal Printhead (8dots / mm)
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- -DC90A series are lined up which can acmodate with all types of barcode labeling printers from Direct to Thermal Transfer, normal to high speed (over 300mm/s). z Applications Bar code label printers Ticket printers General purpose pact printers z Features
1) ROHM new technology “STEP FREE” structure will provide, high corrosion resistance, better resistance against scratching damage, high efficiency. 2) Standard glazed ponents to acmodate thick paper. 3) High speed clock (10MHz) to facilitate external heat history control. 4) Using a hard conductive film as a protective film on the heating element offers excellent resistance to electrostatic damage. 5) patible with the SE3002-DC90A (300dpi) in mechanical specifications, to facilitate the making of a series of printers. z External dimensions (Unit : mm)
