(8 dots / mm)
KD2003-DC10A
The KD2003-DC10A is a 24 V standa rd thick film the rmal printhead w ith a printing speed up to 6 inches / s that has been
developed mainly for label printer use .
zApplications
High speed label printer
High speed bar code printer
High speed ticket printer
Various high speed terminal printers
zFeatures
1) Newly developed thick-film fast response thermal element is empl oyed for th is series an d 6 inches / s o r 150 mm / s i s
possible without thermal history contro l. It is possible to print 10 inches / s or 250 mm / s if external thermal history
control is used.
2) 150km life realized by attributing durable new protection film .
3) New partial glaze construction makes it compatible with the thermal transfer application.
