SH3004-DC90A
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.
zApplications
Barcode printers
Label printers
Packaging printers
ATM
Ticket printers
Scale printers
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) Even without history-control, high-speed printing more than 200mm/s can be achieved at 300dpi with clear print image.
With history-control, 300mm/s printing is also possible at 300dpi.
