NE3002-VA30A Tentative Printheads Near edge thermal printhead (300 dots / inch) NE3002-VA30A NE-VA30 series are the thermal printheads developed for high-speed / high-resolution printing for the market of bar-code printer & scale-printer, based on “step-free” structure. These printheads realize ultra-highspeed printing with long life & high reliability. zApplications Bar code printer Label printer Packaging printer ATM Ticket printer zFeatures 1) High dot reproducibility with step-free structure. 2) About 8° head inclination by near-edge structure, applicable to the large-size platen. Resin type thermal-transfer ink-ribbon can be used. 3) High-hardness protect cote type “W-coat” is employed with 150km abrasion life-time. 4) Even without history-control, high-speed printing more than 300mm / s can be achieved at 300dpi with clear print image. With history-control, 500mm / s printing is also possible at 300dpi. zExternal dimensions (Unit : mm) 7.104±0.3 40±0.3 6±0.5 DOT No.1 SECTION A 54.208 (13) 20±0.3 φ 3 H10 Length 4 MAX.4.5 #2 #20 #4 MAX.11 7.3±0.3 Print Di rection 0369UB 34.0±0.5 MAX.51 (5.896) 66±0.5 24.455±0.3 DOT No.640 φ 3 H10 Effective Depth 3 #1 M3 Effective Depth 3 CONNECTOR B CONNECTOR A #1 #19 TYPE OF PRINTHEAD Rev.A 1/3 NE3002-VA30A Tentative Printheads zEquivalent circuit DOT#1 DOT#640 VH 220µF 35V GND BEO STB2 STB1 LAT LATCH DI 640 1 CLK VDD 0.1µF 50V GND TM TM DI No. DOT No. STB No. DOT No. DI 640 to 1 STB2 640 to 321 STB1 320 to 1 Rev.A 2/3 NE3002-VA30A Tentative Printheads zPin assignments No. Circuit No. Circuit No. Circuit 1 VDD 2 BEO 1 VH 3 GND 4 DI 2 VH 5 N.C. 6 CLK 3 VH 7 LAT 8 GND 4 GND 9 GND 10 N.C. 5 GND 11 N.C. 12 GND 6 GND 13 VDD 14 STB2 15 STB1 16 TM 17 TM 18 SENS1 19 SENS2 20 SENS3 zCharacteristics Symbol Typical Unit Effective printing width − 54.2 mm Dot pitch − 0.0847 mm Total dot number − 640 dots Rave 850 Ω VH 24 V Parameter Average resistance value Applied voltage Applied power PO 0.59 W / dot SLT 0.28 ms Maximum number of dots energized simultaneously − 640 dots Maximum clock frequency − 8 MHz Maximum roller diameter − φ 50 mm Running life / pulse life − 150 / 108 km / pulses Operating temperature − 5 to 45 °C Print cycle Rev.A 3/3 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.
