SE2004-DC94A

SE2004-DC94A Printheads Hight Speed Thermal Printhead (8dots / mm) SE2004-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). Applications Bar code label printers Ticket printers General purpose compact printers Features 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 SE3004-DC94A (300dpi) in mechanical specifications, to facilitate the making of a series of printers.
