High speed thick film thermal printhead
(11.8 dots / mm)
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 both thermal and thermal transfer printing, with a print speed of 100mm/s, the resulting
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 element structure, along with new high-density driver chips 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 300dpi. They achieve the high resolution needed for graphics and
other complex print patterns.
