Thick Film Thermal Printhead (300DPI)

KF3004-GL50A

KF3004-GL50A is developing type of GL40 series which are developed mainly for label printers.
We have adopted low coefficient of abrasion and conductive protection coat to GL40 series which are possible for high
speed and good printing quality.
That is KF3004-GL50A which is 24V standard thick film thermal print head with high speed, high quality of printing, high
durability, long life, and strong resistance to abration.

Applications

!!!!

High speed label printer
Food label printer
High speed ticket printer
High speed terminal printer

Features

!!!!

1) Perform 150km life time adopting new protective coat.
(Perform three times life time by coefficient of abrasion which is about is about 1/10 of current mass-producing coat.)

2) Build in thermal high speeded heater and perform high printing 6 IPS. (150mm / s)

3) Available for thermal transfer printing by adopting specific partial glaze.

4) Use the structure of thermal G-series which had good actual results. And these good results will guarantee high
reliability of GL-series.

5) Line-up for 2 and 3 inches.
