KD2006-DC70A Printhead Thick film thermal printhead (with thermal historical control) KD2006-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) LABEL 10.1±0.4 182 (7) (9) 168 (Effective Print Width) Dot #1 M ax .φ 20 (3.5) Max.40 Max.48 Dot #1344 Max.5 #2 #10 #34 #33 #1 φ3H10 Length 4(Effective Depth 3) 7.3±0.3 13.3±0.3 17.8±0.2 Max.14.0 CONNECTOR B CONNECTOR A φ3H10 (Effective Depth 3) #1 40±0.3 44±0.2 (Heat Element) 44±0.3 80±0.3 124±0.3 3-M3(Effective Depth 3) 1/4 KD2006-DC70A Printhead zEquivalent circuit DOT #1 DOT #1344 VH(COM) 220µF 35V GND 0.1µF 50V VDD(+5) / STB4 / STB3 / STB2 / STB1 / RESET LATCH REGISTER CLKIN4 DI4 DO4 CLKOUT4 CLKIN3 DI3 DO3 CLKOUT3 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. DI4 1344 to 961 / STB4 1344 to 961 CLKIN4 1344 to 961 DI3 960 to 705 / STB3 960 to 705 CLKIN3 960 to 705 DI2 704 to 321 / STB2 704 to 321 CLKIN2 704 to 321 DI1 320 to / STB1 320 to CLKIN1 320 to 1 1 1 Fig.1 2/4 KD2006-DC70A Printhead zPin assignments CONNECTOR A No. CONNECTOR B Circuit No. Circuit No. Circuit 1 VDD 18 / LOAD 1 VH (COM) 2 VDD 19 / RESET 2 VH (COM) 3 NC 20 START 3 VH (COM) 4 NC 21 TM 4 VH (COM) 5 SEL2 22 TM 5 VH (COM) 6 SEL1 23 DI2 6 GND 7 CLKIN4 (CP) 24 DO2 7 GND GND 8 CLKOUT4 25 DI1 8 9 CLKIN3 26 DO1 9 GND 10 CLKOUT3 27 / STB2 10 GND 11 DI4 28 / STB1 12 DO4 29 CLKIN2 13 DI3 30 CLKOUT2 14 DO3 31 CLKIN1 15 / STB4 32 NC 16 / STB3 33 NC 17 INC 34 NC zCharacteristics Parameter Symbol Typical Unit − 168 mm Dot pitch − 0.125 mm Total dot number − 1344 dots Rave 650 Ω VH 24 V Effective printing width Average resistance value Applied voltage PO 0.75 W/dot SLT 0.49 ms Maximum number of dots energized simultaneously − 1344 dots Maximum clock frequency − 8 MHz Maximum roller diameter − φ20.0 Running life / pulse life − 150/(1×10 ) km/pulses Operating temperature − 5 to 45 °C Applied power Print cycle mm 8 3/4 KD2006-DC70A Printhead zData sheets 1.6 1.0 SLT : 0.82ms/line MAXIMUM ENERGY (mJ/dot) OPTICAL DENSITY Level1 0.9 1.4 1.2 1.0 0.8 0.6 0.4 Level2 0.8 0.7 Level3 0.6 0.5 Level4 0.4 Level5 Level6 0.3 0.2 0.2 0.1 0.0 0.00 0.05 0.10 0.15 0.20 0.25 0.30 0.35 0.40 0.0 0 0.2 0.4 0.6 0.8 1.0 1.2 ENERGY (mJ/dot) SCANNING LINE TIME (ms/line) Fig.2 Representative density curve Fig.3 Maximum energy curve 1.4 4/4 Appendix Notes No technical content pages of this document may be reproduced in any form or transmitted by any means without prior permission of ROHM CO.,LTD.
