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. 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. !Applications Label printers Ticket printers Terminal 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) One rank resistance value of 1250Ω ± 3% eliminates the inconvenience of rank selection. 3) 2-inch, 3-inch and 4-inch series are available. !External dimensions (Units : mm) 91 81.312 (EFFECTIVE PRINT WITH) (4.844) DOT #960 MAX. 20 DOT #1 5.1±0.4 4±0.2 2.6±0.1 No.15 CONNECTOR B No.1 No.15 CONNECTOR A (10.2) 5±0.2 81±0.2 2-M3 EFFECTIVE DEPTH 3 5.1±0.1 φ1 No.1 8.0 1/4 KF3003-GD31A Printheads !Equivalent circuit VH GND DOT #960 DOT #1 VH GND VDD 8 7 6 5 4 3 2 1 STB1 STB4 STB2 STB3 LATCH REGISTER DI2 DO2 LAT CLK DO1 DI1 SHIFT REGISTER SHIFT REGISTER TM TM THERMISTOR 30kΩ B:3950 CONNECTOR B CONNECTOR A STB No. 1 2 3 4 Dot No. 1 ∼ 192 193 ∼ 448 449 ∼ 704 705 ∼ 960 dots / STB 192 256 256 256 DI No. 1 2 Dot No. 1 ∼ 448 449 ∼ 960 dots / STB 448 512 Fig.1 2/4 KF3003-GD31A Printheads !Pin assignments CONNECTOR A No. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 Circuit VH VH VH VH DI1 DO1 LAT CLK STB1 STB2 GND GND GND GND GND CONNECTOR B No. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 Circuit GND GND GND GND STB3 STB4 VDD TM TM DO2 DI2 VH VH VH VH !Timing chart tw CLK CLOCK (CLK) t setup DI DATA IN (DI) "High":BLACK "Low" :WHITE DATA OUT (DO) "High":BLACK "Low" :WHITE t hold DI td DO t setup LAT LATCH (LAT) "High":HOLD "Low" :THROUGH tw LAT STROBE (STB) t hold LAT t setup STB tdo DRIVER OUT tdo Fig.2 3/4 KF3003-GD31A Printheads !Characteristics Parameter Effective printing width Dot pitch Total dot number Average resistance value Applied voltage Applied power Print cycle Pulse width Maximum number of dots energized simultaneously Maximum clock frequency Maximum roller diameter Running life / pulse life Operating temperature Symbol − − − Rave VH PO SLT TON − − − − − Typical 81.312 0.0847 960 1250 24 0.42 0.82 0.311 512 8 φ18.0 50/5×10 5~45 7 Unit mm mm dots Ω V W/dot ms ms dots MHz mm km/pulses °C !Electrical characteristic curves 0.8 Paper : KF50-HDA (OJI) 0.7 0.6 ENERGY (mJ/dot) OPTICAL DENSITY 1.8 1.6 1.4 1.2 1.0 0.8 0.6 0.4 0.2 ENERGY (mJ/dot) 0.8 SLT : 0.82ms/line 0.7 0.6 0.5 0.4 0.3 0.2 0.1 0 0 1 2 3 4 5 0.5 .
