NF3004-WA30A Printhead Under development High speed thermal printhead (with thermal historical control) NF3004-WA30A NF-WA30 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 Barcode printer Label printer Packaging printer Ticket printer Scale printer ATM zFeatures 1) High dot reproducibility with step-free structure. 2) High-hardness protect cote type “W-coat” is employed with 150km abrasion life-time. 3) 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. 1/4 NF3004-WA30A Printhead Under development zExternal dimensions (Unit : mm) DOT No.1 124±0.5 6±0.5 108.416 Ma x.φ MAX.51 20 (3.5) (7.792) Max.4.5 Max.11 #2 #1 Type of PRINTHEAD #20 CONNECTOR:A #19 #6 #1 CONNECTOR:B 3-M3 Effective Depth 3 100±0.2 17.8±0.2 14.208±0.3 40±0.3 80±0.3 (21.3) 2.8±0.2 31.0±0.5 (43) φ 3 H10 Effective Depth 3 7.3±0.3 10±0.2 φ 3 H10 Length 4 Effective Depth 3 DOT No.1 2/4 NF3004-WA30A Printhead Under development zEquivalent circuit DOT #1280 VH (COM) DOT #1 220µF 35V GND 0.1µF 50V VDD (+5) / STB2 / STB1 BEO / RESET LATCH REGISTER SHIFT REGISTER SHIFT REGISTER CLK (CP) DI2 DI1 / LOAD START TO EACH IC INC SEL2 SEL1 TM TM THERMISTOR 30kΩ B: 3950K DI, STB DIVISION DOT No. CORRESPONDENCE DI No. DOT No. / STB No. DI2 1280 to 641 / STB2 DI1 640 to DOT No. 1280 to 641 / STB1 1 640 to 1 zPin assignments CONNECTOR : A CONNECTOR : B No. Circuit No. Circuit No. Circuit No. Circuit 1 VDD 2 BEO 1 VH (COM) 2 VH (COM) 3 GND 4 DI2 3 VH (COM) 4 GND 5 5 GND 6 GND GND 6 CLK (CP) 7 /LOAD 8 START 9 INC 10 DI1 11 SEL2 12 SEL1 13 /RESET 14 /STB2 15 /STB1 16 TM 17 TM 18 SENS1 19 SENS2 20 SENS3 3/4 NF3004-WA30A Printhead Under development zCharacteristics Parameter Symbol Typical Unit − 108.416 mm Dot pitch − 0.0847 mm Total dot number − 1280 dots Rave 850 Ω VH 24 V Effective printing width Average resistance value Applied voltage PO 0.57 W/dot SLT 0.28 ms Maximum number of dots energized simultaneously − 1280 dots Maximum clock frequency − 8 MHz Maximum roller diameter − φ20 Running life / pulse life − 150/(1×10 ) km/pulses Operating temperature − 5 to 45 °C Applied power Print cycle mm 8 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.
