Printheads

Compact high speed thick film
thermal printhead (8dots / mm)

KD2003-DG12A

KD2003-DG12A built in new and high density driver IC developed by the cutting edge technologies realizes the highest
speed in the same class (250mm/s) at both Thermal Transfer and Direct Thermal.
This Thermal Printhead is suitable for POS, ATM, KIOSK and TICKET industries which require High Speed / High
Density and Graphic printing.
By the implementation of highly durable pro tective coat, it achi eves 150km as the standard abrasion life.

zApplications

Label printers
Ticket printers
POS printers
ATM printers
KIOSK printers
T erminal printers

zFeatures

1) The use of a special partial glaze and the latest heating elemen t structure, along w ith new high-de nsity driver chip s that
can accept big current, has allowed ROHM to achieve print speeds of 250mm/s, the fastest in its class ( with historical
control ).

2) One rank resistance value of 650Ω ± 3% eliminates the inconvenience of rank selection.

3) The required driving voltage of 3.13 to 5.25V allows wide range of power supply voltage setting. This also allows
multiple choice of electronic co mponents fo r printers.

4) With the standard abrasion life of 150km, long life is achieved agains t the largely abrasive thermal paper .
