SH2004-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
Bar code printers
Card printers
Ticket printers
General purpose compact printers
zFeatu res
1) ROHM new technology “STEP FREE” structure will provide, high corrosion resistance, better resistance against
scratching damage, high ef ficiency.
2) Inclined toward the printing surface to provide excellent printing qu ality even for cards and thick pap er .
3) Prints directly on printing mediu m 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 w hen installe d enables smal ler printers.
6) Compatible with the SH3004-DC90A (300dpi) in mechanical specifications, to facilitate the making of a series of
printers.
