KD2002-DF10A
Using its expertise in LSI technolo gy , R OHM has developed new high density driver ch ips for use in the KD2002-DF10A .
Capable of being employed for bot h thermal and therm al transfer pr inting, with a print speed of 25 0mm/s, the resulti ng
print heads are the fastest in their c lass. This high-speed and high-density printing answers the needs of POS, ATM,
KIOSK and ticket printing devices, which are increasingly being called upon to produce graphical output.
zApplications
POS printers
ATM printers
KIOSK printers
Ticket 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 with using thermal history control, the
fastest in its class.
2) Standard printheads in the line up are capable of 203 or 300 dpi. They achieve the high resolution needed for graphics
and other complex print patterns.
3) One rank resistance value of 650Ω ± 3% eliminates the inconvenience of rank selection.
4) The required driving voltage of 3.15 to 5.25V allows wide range of power supply voltage setting. This also allows
multiple choice of electronic co mponents fo r printers.
5) 2-inch, 3-inch and 4-inch series are available.
