Hight Speed Thermal Printhead  
(8dots / mm)  
SE2004-DC90A  
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 accommodate with all types of  
barcode labeling printers from Direct to Thermal Transfer, normal to high speed (over 300mm/s).  
zApplications  
Bar code label printers  
Ticket printers  
General purpose compact printers  
zFeatures  
1) ROHM new technology “STEP FREE” structure will provide, high corrosion resistance, better resistance against  
scratching damage, high efficiency.  
2) Standard glazed components to accommodate thick paper.  
3) High speed clock 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) Compatible with the 300dpi in mechanical specifications, to facilitate the making of a series of  
printers.
