NE3104-VC11A Printheads For Photo Color Printers (310DPI;dots/inch) NE3104-VC11A NE3104-VC11 series is newly developed for photo color printers as (color print) thermal printheads, high speed, high quality printing is acheved with several new technologies. Printing method is available for sublimination type of thermal transterence. ● Application Home printer Photo KIOSK ● Features 1) 9° tit-angle with near-edge structure to work with larger platen. 2) High quality printing with less unever imaging by employing the glaze of very little undulation. 3) Resistance variance less than ±1% in the head using special pulse trimming technologies. ● External Dimension (Unit:mm) 114.8 104.96 Dot #1280 5.685 No.1 ction Print Dire 22.7 (1.06) Dot #1 (2.3) No.24 Typ.6° Fig. 1 External Dimension Note：No heat control function inside the thermal printhead. External heat history control is required for high speed printing. 1/4 NE3104-VC11A Printheads ● Equivalent circuit DOT #1280 DOT #1 VH P-GND L-GND 10 9 8 7 6 5 4 3 2 1 Vdd /STB /LAT LATCH REGISTER CLK SHIFT REGISTER 10 DI 10 SHIFT REGISTER 9 SHIFT REGISTER 2 SHIFT REGISTER 1 DI 9 DI 8 DI 7 DI 6 To each Shift Register DI 5 DI 4 DI 3 DI 2 DI 1 TM L-GND DI No. Dot No. DI No. Dot No. 10 1280 to 1153 5 640 to 513 9 1152 to 1025 4 512 to 385 8 1024 to 897 3 384 to 257 7 896 to 769 2 256 to 129 6 768 to 641 1 128 to 1 Fig. 2 Equivalent circuit 2/4 NE3104-VC11A Printheads ● Pin assignments No. Circuit No. Circuit No. Circuit 1 VH 2 VH 3 VH 4 VH 5 P-GND 6 P-GND 7 P-GND 8 P-GND 9 TM 10 L-GND 11 VDD 12 DI10 13 DI9 14 DI8 15 DI7 16 DI6 17 DI5 18 DI4 19 DI3 20 DI2 21 DI1 22 CLK 23 /STB 24 /LAT ● Timing chart tw CLK CLK (CLOCK) t setup DI t hold DI DI (DATA IN) "High”: BLACK "LOW”: WHITE t setup LAT t hold LAT /LAT (LATCH) "High": HOLD "LOW”: THROUGH tw LAT t setup STB /STB (STROBE) tdo tdo DRIVER OUT Fig. 3 Timing chart 3/4 NE3104-VC11A Printheads ● Characteristics Parameter Symbol Typical Unit Effective printing width 104.96 mm Dot pitch 0.0820 mm Total dot number 1280 dots Average resistance value Rave 5400 Ω Applied voltage VH 24 V Applied power P0 0.102 W/dot Print cycle SLT 4.0 ms/line Pulse width TON 2.8 ms 1280 dots Maximum clock frequency 10 MHz Maximum rolls diameter 52 mm Running life/pulse life 2/5×107 km/pulses Operating temperature 5 to 45 °C Maximum number of dots energized simultaneously Electrical characteristic 50 45 40 35 RESISTANCE kΩ ● 30 25 20 15 10 5 0 -20 0 20 40 60 TEMPERATURE (℃) 80 Fig. 4 Thermistor curve 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.
