KF2002-GD31A
Using its expertise in LSI technology, ROHM has developed new high density driver chips for use in the KF2002-GD31A . Capable of being employed for both thermal and thermal transfer printing, with a print speed of 200mm/s, the resulting print heads are the fastest in their class. 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. Applications POS printers ATM printers KIOSK printers Ticket printers Features 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 200mm/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 800 3% eliminates the inconvenience of rank selection. 4) Achieves the high life expectancy by forming the electrically conductive hard over coating layer on the heat element. 5) 2-inch, 3-inch, 4-inch and 5.5-inch series are available.
