| NF3004-RE10A Printheads Under development For Color Photo Printers (300DPI ; dots / inch) NF3004-RE10A The NF3004-RE10 Series are suitable for small photo printers which can make direct print out from digital still cameras and mobile phones. ROHM's technology based on "Step-free" structure enables battery drive, and high resolution printing quality. Applications Home printers Mobile Photo printers Photo kiosk terminals "Print club" (color photo printer) terminals Features 1) NF3004-VC20 is drivable with batteries, thanks to it's low energy consumption. 2) NF3004-VC20 enables full color printing by keeping the adjacent resistance variation less than 1.5%. 3) Employing of the driver IC capable of high-speed data transfer at 3.3 circuit supply voltage makes the gradation printing control easier. 4) High dot reproducibility with step-free structure. External dimensions (Unit : mm) 114.20.2 (5.835) (3.02) 108.16 Dot #1280 CL Dot #1 Max.14 0 1 Note: No heat control function inside the thermal printhead. External heat history control is required for high speed printing. 1/4 NF3004-RE10A Printheads Equivalent circuit Under development DOT #1280 VH 0.47F GND 1280 1153 ~ DOT #1 1152 1025 ~ 1024 897 ~ 896 769 ~ 768 641 ~ 640 513 ~ 512 385 ~ 384 257 ~ 256 129 ~ 128 1 ~ VDD /STB2 /STB1 /LAT2 LATCH REGISTER 2 LATCH REGISTER 1 /LAT1 CLK1 CLK2 DI 10 DI 9 DI 8 DI 7 DI 6 DI 5 DI 4 DI 3 DI 2 DI 1 TM SHIFT REGISTER 10 SHIFT REGISTER 9 SHIFT REGISTER 2 SHIFT REGISTER 1 To each Shift Register THERMISTOR 10k B3380K GND DI No. 10 9 8 7 6 DOT No. 1280 to 1153 1152 to 1025 1024 to 897 896 to 769 768 to 641 DI No. 5 4 3 2 1 DOT No. 640 to 513 512 to 385 384 to 257 256 to 129 128 to 1 /STB No. 2 1 DOT No. 1280 to 641 640 to 1 Fig.1 2/4 NF3004-RE10A Printheads Pin assignments No. 1 4 7 10 13 16 19 22 25 28 Circuit GND VH GND TM DI 8 DI 5 DI 2 /STB 1 CLK 1 VH No. 2 5 8 11 14 17 20 23 26 29 Circuit VH GND /LAT 2 DI 10 DI 7 DI 4 DI 1 /LAT 1 GND VH No. 3 6 9 12 15 18 21 24 27 30 Circuit VH CLK 2 /STB 2 DI 9 DI 6 DI 3 VDD GND VH GND Under development Timing chart tw CLK CLK (CLOCK) t setup DI t hold DI DI(DATA IN) "High" : BLACK "LOW" : WHITE t setup LAT LAT (LATCH) "High" : HOLD "LOW" : THROUGH t hold LAT tw LAT STB (STROBE) t setup STB tdo DRIVER OUT tdo Fig.2 3/4 NF3004-RE10A Printheads Characteristics Parameter Effective printing width Dot pitch Total dot number Average resistance value Applied voltage Applied power Print cycle Pulse width Maximum number of dots energized simultaneously Maximum clock frequency Maximum rolls diameter Running life / pulse life Operating temperature Under development Symbol - - - Rave VH PO SLT TON - - - - - Typical 108.16 0.0845 1280 2800 13.3 0.061 4.5 2.25 640 16 10 2/5x107 5 to 45 Unit mm mm dots V W/dot ms/line ms dots MHz mm km/pulses C 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.
