KD3004-DC70A Printhead Thick film thermal printhead (with thermal historical control) KD3004-DC70A DC70 series has our own internally developed heat-history control function. This product is best suited for applications which require 24 hours operation like factory production lines. zApplications High speed label printer High speed bar code printer High speed ticket printer Various high speed terminal printers zFeatures 1) Newly developed thick-film fast response thermal element and driver LSI with the function of thermal history control which is added the future history control are employed for this series. It is possible to print with super high speed of 10 inches / s or 250 mm / s. 2) 150km life realized by attributing durable new protection film. 3) New partial glaze construction makes it compatible with the thermal transfer application. zExternal dimensions (Unit : mm) 3-M3(Effective Depth 3) LABEL 118 80±0.3 (19) 14.208±0.2 (5) 40±0.3 Dot #1 15±0.3 17.8±0.2 7.3±0.3 15.3±0.3 Ma x.φ 20 (20.8) 95±0.3 25±0.5 108.416(Effective Print Width) Dot #1280 (3) Max.36 Max.45 (4.792) 6.1±0.4 Max.12 Max.5.5 #2 #20 #1 #6 φ3H10 Length 4 (Effective Depth 3) φ3H10 (Effective Depth 3) #1 #19 CONNECTOR A CONNECTOR B 1/3 KD3004-DC70A Printhead zEquivalent circuit DOT #1 DOT #1280 VH(COM) 100µF×2 35V GND 0.1µF 50V VDD(+5) / STB2 / STB1 / RESET LATCH REGISTER CLKIN2 DI2 DO2 CLKOUT2 CLKIN1 DI1 DO1 / LOAD START TO EACH IC INC SEL2 SEL1 TM THERMISTOR 30kΩ B : 3950 TM DI No. DOT No. / STB No. DOT No. CLK No. DOT No. DI2 1280~641 / STB2 1280~641 CLKIN2 1280~641 DI1 640~ / STB1 1 640~ 1 CLKIN1 640~ 1 Fig.1 zPin assignments CONNECTOR A CONNECTOR B No. Circuit No. Circuit No. Circuit 1 VDD 11 / RESET 1 VH (COM) 2 VDD 12 START 2 VH (COM) 3 SEL2 13 DO1 3 VH (COM) 4 SEL1 14 DO2 4 GND 5 CLKIN2 (CP) 15 TM 5 GND 6 NC 16 TM 6 GND 7 DI2 17 / STB2 8 DI1 18 / STB1 9 INC 19 CLKOUT2 10 / LOAD 20 CLKIN1 2/3 KD3004-DC70A Printhead zCharacteristics Parameter Symbol Typical Unit Effective printing width − 108.416 mm Dot pitch − 0.0847 mm Total dot number − 1280 dots Rave 1000 Ω Average resistance value Applied voltage VH 24 V Applied power PO 0.51 W/dot SLT 0.41 ms Maximum number of dots energized simultaneously − 1280 dots Maximum clock frequency − 8 MHz Maximum roller diameter − φ20.0 mm Running life / pulse life − 150/(1×108) km/pulses Operating temperature − 5 to 45 °C Print cycle zData sheets 1.6 SUPPLY ENERGY (Max.)
