SE3004-DC94A Printhead High speed thermal printhead (300 dots / inch) SE3004-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. SE300*-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 Barcode printers Label printers Packaging printers ATM Ticket printers Scale 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. zDimensions (Unit : mm) DOT No.1 6±0.2 (26) Min. 4.3 (3.5) (7.792) Max. 48 Max.φ20 124±0.5 108.4 Max.5 #2 TYPE OF PRINTHEAD #1 #26 #6 #25 JST B6PS-VH HIROSE HIF3FC-26PA-2.54DS Max.10 #1 3-M3 EFFECTIVE DEPTH 3 100±0.2 2.8±0.2 7.3±0.3 17.8±0.2 (21.3) 25±0.5 (36) 10±0.2 14.208±0.2 φ3 H10 EFFECTIVE DEPTH 3 φ3 H10 LENGTH 4 EFFECTIVE DEPTH 3 40±0.3 (22) 80±0.3 DOT No.1 Note: No heat history control function inside the thermal printhead.
