ROHM KD3003

Thick Film Thermal Printhead (300dpi)
KD3003-DC92A
KD3003-DC92A is developing type of GL40 series which are developed mainly for label printers.
We have adopted low coefficient of abrasion and conductive protection coat to GL40 series which are possible for high speed and
good printing quality.
That is KD3003-DC92A which is 24V standard thick film thermal print head with high speed, high quality of printing, high durability,
long life, and strong resistance to abration.
zApplications
High speed label printer
Food label printer
High speed ticket printer
High speed terminal printer
zFeatures
1) Perform 150km life time adopting new protective coat.
(Perform three times life time by coefficient of abrasion which is about is about 1/10 of current mass-producing coat.)
2) Build in thermal high speeded heater and perform high printing 4 IPS. (100mm / s)
3) Available for thermal transfer printing by adopting specific partial glaze.
