Thick Film Thermal Printhead (300d pi)
KD3004-DC92A
KD3004-DC92A is developing type of GL40 se ries which are de veloped mainly for label printe rs.
We have adopted low coefficient of abrasio n and c ond uctive pr otect ion co at to GL40 seri es which are possib le for h igh sp eed and
good printing quality.
That is KD3004-DC92A which is 24V standard thick film therm al print head with high spee d, high qu ality of p rinting, h igh dura bility ,
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 coe fficient o f abrasion w hich is about is about 1 /10 of current mass-p roducing coat.)
2) Build in thermal high speeded heater and perfo rm high printing 4 IPS. (100mm / s)
3) Available for thermal transfer printing by adopting specific partial glaze.
