SH3004-DC90A Tentative Printhead Near edge thermal printhead (300 dots / inch) SH3004-DC90A SH-DC90 series was developed with two key structures step-free and near edge for the packaging printer market which requires high speed continuous printing. It is suitable for printers in factory line where high speed 24 hours continuous printing is required. zApplications Barcode printers Label printers Packaging printers ATM Ticket printers Scale printers zFeatures 1) ROHM new technology “STEP FREE” structure will provide, high corrosion resistance, better resistance against scratching damage, high efficiency. 2) 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 200mm/s can be achieved at 300dpi with clear print image. With history-control, 300mm/s printing is also possible at 300dpi. zExternal dimensions (Unit : mm) 124±0.5 DOT No.1 6±0.5 108.416 MAX.51 BU9630 Print Direct ion (7.792) Max.4.5 Max.11 #2 Type of PRINTHEAD #1 #20 CONNECTOR:A #19 #6 #1 CONNECTOR:B 100±0.2 (21.2) 20.45±0.2 2.8±0.2 (43) 31.0±0.5 7.3±0.3 3-M3 Effective Depth 3 10±0.2 φ3 H10 Effective Depth 3 φ3 H10 Length 4 Effective Depth 3 14.208±0.3 40±0.3 80±0.3 DOT No.1 1/3 SH3004-DC90A Tentative Printhead zEquivalent circuit DOT#1 DOT #1280 VH 220µF 35V GND BEO STB2 STB1 LAT LATCH 641 1280 1 640 DI 2 DI 1 CLK VDD 0.1µF 50V GND TM TM DI No. DOT No. DI 2 1280 to 641 DI 1 640 to 1 STB No. DOT No. STB2 1280 to 641 STB1 640 to 1 2/3 SH3004-DC90A Tentative Printhead zPin assignments HIROSE JST No. Circuit No. Circuit No. Circuit 1 VDD 2 BEO 1 VH 3 GND 4 DI2 2 VH 5 N.C. 6 CLK 3 VH 7 LAT 8 GND 4 GND 9 GND 10 DI1 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 Parameter Symbol Typical Unit Effective printing width − 108.4 mm Dot pitch − 0.0847 mm Total dot number − 1280 dots Rave 850 Ω VH 24 V Average resistance value Applied voltage Applied power PO 0.57 W / dot SLT 0.42 ms Maximum number of dots energized simultaneously − 1280 dots Maximum clock frequency − 10 MHz Maximum roller diameter − φ 50 mm Running life / pulse life − 150 / 108 km / pulses Operating temperature − 5 to 45 °C Print cycle 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.
