KD3008-DF54A
Using its expertise in LSI technology, ROHM has developed new high density driver chips for use in the KD3008-DF54A.
Capable of being employed for bot h thermal and therm al transfer pr inting, with a print speed of 10 0mm/s, the resulti ng
print heads are the fastest in their class. The 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
Label 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 100mm/s with using thermal history control, the
fastest in its class.
2) Standard printheads in the line up are capable of 300d pi. They achieve the high re solution needed for graphi cs and
other complex print patterns.
