KD2002-DC70A

KD2002-DC70A Printheads Thick film thermal printhead (with thermal historical control) KD2002-DC70A DC70 series has our own internally developed heat-history control function. This product is best suited for applications which require 24 hours operation like factory production lines. Applications High speed label printer High speed bar code printer High speed ticket printer Various high speed terminal printers Features 1) Newly developed thick-film fast response thermal element and driver LSI with the function of thermal history control which is added the future history control are employed for this series. It is possible to print with super high speed of 10 inches / s or 250mm / s. 2) 150km life realized by attributing durable new protection film. 3) New partial glaze construction makes it compatible with the thermal transfer application.
