Thick film thermal printhead
(8 dots / mm)
KD2004-DC10A
The KD2004-DC10A is a 24 V standard thick film thermal printhead with 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 employed for this series and 6 inches / s or 150mm / s is
possible without thermal history control. It is possible to print 10 inches / s or 250mm / 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.
