KD3004-DF10A Printheads Compact high speed thick film thermal printhead (12 dots / mm) KD3004-DF10A Using its expertise in LSI technology, ROHM has developed new high density driver chips for use in the KD3004-DF10A . 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. zApplications Label printers Ticket printers Terminal printers zFeatures 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 1000Ω ± 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. zDimensions (Unit : mm) 118 108.416 (EFFECTIVE PRINT WIDTH) DOT #1 No.15 φ2 0.0 2.6±0.1 Max. 20 DOT #1280 5.1±0.4 4±0.2 No.1 No.15 No.1 CONNECTOR A 4±0.2 110±0.2 5.1±0.1 (10.2) CONNECTOR B 2-M3 (EFFECTIVE DEPTH 3) Rev.A 1/4 KD3004-DF10A Printheads zEquivalent circuit DOT #1280 VH DOT #1 VH GND GND L /S VSF 10 9 8 7 6 5 4 3 2 1 VDD STB1 ST B4 STB2 ST B3 LAT L A T C H R E G I S TE R DI 2 S H IF T RE G I S T E R D O2 TM CLK DO1 DI1 S H I F T R E G I S TE R TH E R M I S TO R 30kΩ B:3950 TM CONNECTOR B CONNECTOR A STB No. Dot No. dots / STB DI No. Dot No. dots / STB 1 1 ∼ 384 384 1 1 ∼ 640 640 2 385 ∼ 640 256 2 640 ∼ 1280 640 3 641 ∼ 896 256 4 897 ∼ 1280 384 Fig.1 Rev.A 2/4 KD3004-DF10A Printheads zPin assignments CONNECTOR A CONNECTOR B No. Circuit No. Circuit 1 VH 1 GND 2 VH 2 GND 3 VH 3 GND 4 VH 4 GND 5 DI1 5 STB3 6 DO1 6 STB4 7 LAT 7 VDD 8 CLK 8 TM 9 STB1 9 TM 10 STB2 10 DO2 11 GND 11 DI2 12 GND 12 VSF 13 GND 13 VH 14 GND 14 VH 15 GND 15 VH zTiming chart tw CLK CLOCK (CLK) t setup DI DATA IN (DI) "High":BLACK "Low" :WHITE t hold DI td DO DATA OUT (DO) "High":BLACK "Low" :WHITE t hold LAT t setup LAT LATCH (LAT) "High":HOLD "Low" :THROUGH tw LAT t setup STB STROBE (STB) tdo tdo DRIVER OUT Fig.2 Rev.A 3/4 KD3004-DF10A Printheads zCharacteristics Symbol Typical Unit Effective printing width − 108.416 mm Dot pitch − 0.0847 mm − 1280 dots Rave 1000 Ω Parameter Total dot number Average resistance value Applied voltage VH 24 V Applied power PO 0.49 W/dot Print cycle SLT 0.83 ms Pulse width TON 0.26 ms Maximum number of dots energized simultaneously − 640 dots Maximum clock frequency − 16 MHz Maximum roller diameter − φ18.0 mm Running life / pulse life − 50/5×107 km/pulses Operating temperature − 5 to 45 °C zElectrical characteristic curves 0.8 0.8 1.8 0.6 1.4 0.5 0.4 0.3 0.2 SLT : 0.82ms/line 0.7 0.6 ENERGY (mJ/dot) 1.6 OPTICAL DENSITY ENERGY (mJ/dot) Paper : KF50-HDA (OJI) 0.7 1.2 1.0 0.8 0.6 1 2 3 4 5 SCANNING LINE TIME (ms/line) 0.0 0.00 0.05 0.10 0.15 0.20 0.25 0.30 ENERGY (mJ/dot) Fig.3 Adaptive speed chart 0.3 0.1 0.2 0 0 0.4 0.2 0.4 0.1 0.5 Fig.4 Representative density curve 0 0 1 2 3 4 5 SCANNING LINE TIME (ms/line) Fig.5 Maximum energy curve 180 160 RESISTANCE : (kΩ) 140 120 100 80 60 40 20 0 −20 −10 0 10 20 30 40 50 60 70 TEMPERATURE : (°C) Fig.6 Thermistor curve Rev.A 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.
