Printheads
Near edge thermal printhead (8dots / mm)
SH-DC90 series was developed with two key structures step-free and near edge for the packaging printer market which requires high speed continuous printing. It is suitable for printers in factory line where high speed 24 hours continuous printing is required. z Applications Bar code printers Card 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) Inclined toward the printing surface to provide excellent printing quality even for cards and thick paper. 3) Prints directly on printing medium that cannot be bent. 4) Using a hard conductive film as a protective film on the heating element offers excellent resistance to electrostatic Damage. 5) Being low-profile when installed enables smaller printers. 6) patible with the SH3004-DC90A (300dpi) in mechanical specifications, to facilitate the making of a series of printers. z External dimensions (Unit : mm)
