KD3002-DF10A printheads 1/4 compact high speed thick film thermal printhead (12 dots / mm) KD3002-DF10A using its expertise in lsi technology, rohm has developed new high density driver chips for use in the KD3002-DF10A . capable of being employed for both thermal and thermal transf er printing, with a print speed of 200mm/s, the resulting print heads are the fastest in their class. the high-speed and high-density printing answers the needs of atm, kiosk and ticket printing devices, which are increasingly being called upon to produce graphical output. z applications label printers ticket printers terminal printers z features 1) the use of a special partial glaze and the latest heating elem ent structure, along with new high-density driver chips that can accept big current, has allowed rohm to achieve print s peeds of 200mm/s with using thermal history control, the fastest in its class. 2) one rank resistance value of 1000 ? 3% eliminates the inconvenience of rank selection. 3) 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 components for printers. 4) 2-inch, 3-inch, 4-inch and 8-inch series are available. z external dimensions (unit : mm) 65 54.208 (effective print width) 55 0.2 2-m3 (effective depth 3) 5 0.2 5.1 0.1 (10.2) dot #640 2.6 0.1 max. 20 dot #1 connector b connector a no. 15 no. 1 no. 1 no. 15 5.1 0.4 4 0.2 20.0
