Thick film thermal printhead
(8 dots / mm)
KD2004-DC10A
The KD2004-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 respon se th ermal el e ment is emp loy ed for thi s se ries an d 6 inch e s / s o r 1 50mm / s is
possible without thermal history co ntrol. It is possible to print 10 inches / s or 250mm / s if externa l thermal history
control is used.
2) 150km life realized by attributing durable new protection film.
3) New partial glaze construction makes it compatibl e with the th ermal transfer application .
