Near edge thermal printhead
(with thermal historical control)
SH2004-DC70A
SH2004-DC70A
SH-DC70 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.
zApplications
Bar code printer
Label printer
Packaging printer
ATM
Ticket printer
zFeatures
1) ROHM new technology “STEP FREE” structure will provide, high corrosion resistance, better resistance against
scratching damage, high efficiency.
2) Head inclination by near-edge structure, applicable to the large-size platen. Resin type thermal-transfer ink-ribbon can
be used.
3) High-hardness protect cote type “W-coat” is employed with 150km abrasion life-time.
4) A built in history-control functionality, high-speed printing up to 300mm / s can be achieved with clear print image.
