| KF3003-GL50A Printheads Thick Film Thermal Printhead (300DPI) KF3003-GL50A KF3003-GL50A is developing type of GL40 series which are developed mainly for label printers. We have adopted low coefficient of abrasion and conductive protection coat to GL40 series which are possible for high speed and good printing quality. That is KF3003-GL50A which is 24V standard thick film thermal print head with high speed, high quality of printing, high durability, long life, and strong resistance to abration. !Applications High speed label printer Food label printer High speed ticket printer High speed terminal printer !Features 1) Perform 150km life time adopting new protective coat. (Perform three times life time by coefficient of abrasion which is about is about 1/10 of current mass-producing coat.) 2) Build in thermal high speeded heater and perform high printing 6 IPS. (150mm / s) 3) Available for thermal transfer printing by adopting specific partial glaze. 4) Use the structure of thermal G-series which had good actual results. And these good results will guarantee high reliability of GL-series. 5) Line-up for 2 and 4 inches. !External dimensions (Units : mm) TYPE OF PRINTHEAD 91 6.10.4 (5) 3H10 Length 4 (Effective Depth 3) 3-M3(Effective Depth 3) 20.6560.2 400.3 200.3 DOT #960 (4.844) 81.312(Effetive Print Width) DOT #960 DOT #1 250.5 Max.45 Max.36 2 0 (20.8) (3) 15.30.3 Max.10 #2 #20 #6 #1 Max.5.5 60.50.3 20.50.3 3H10 (Effective Depth 3) #1 #19 HIROSE HIF3FC-20PA-2.54DS JST B6PS-VH 17.80.2 7.30.3 KF3003-GL50A Printheads !Equivalent circuit VH GND 15 VDD STB4 STB3 STB2 STB1 64 OUTPUT EACH DOT #960 DOT #1 14 13 12 9 8 5 4 2 1 LAT LATCH REGISTER CLK SHIFT REGISTER SHIFT REGISTER SHIFT REGISTER SHIFT REGISTER DI4 DO4 DI3 DO3 DI2 DO2 DI1 DO1 TM TM CONNECTOR THERMISTOR 30k B : 3950 DI No. DI1 DI2 DI3 DI4 DOT No. 1~256 257~512 513~768 769~960 STB No. STB1 STB2 STB3 STB4 DOT No. 1~256 257~512 513~768 769~960 Fig. 1 !Pin configuration CONNECTOR A No. 1 2 3 4 5 6 7 8 9 10 Circuit No. Circuit CONNECTOR B No. 1 2 3 4 5 6 Circuit VH VH VH GND VDD GND VDD STB4 11 12 13 14 15 16 17 18 19 20 TM TM DI3 DO3 DI2 DO2 STB2 STB1 DI1 DO1 GND GND GND CLK DI4 DO4 STB3 LAT KF3003-GL50A Printheads !Timing chart Min.30ns CLOCK (CLK) Min.30ns DATA IN (DI) "High" : BLACK "Low" : WHITE DATA OUT (DO) "High" : BLACK "Low" : WHITE Min.10ns Max.120ns Min.200ns LATCH (LAT) "High" : HOLD "Low" : THROUGH Min.50ns Min.100ns STROBE (STB) Min.300ns Max.10s DRIVER OUT Max.10s Fig.2 !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 roller diameter Running life / pulse life Operating temperature Symbol Rave VH PO SLT TON Typ. 81.31 0.0847 960 1250 24 0.42 0.83 0.284 960 8 20.0 150 / 1x10 5~45 8 Unit mm mm dots V W / dot ms ms dots MHz mm km / pulses C KF3003-GL50A Printheads !Data sheet 0.40 0.35 0.30 ENERGY : (mJ / dot) 1.6 1.4 1.2 SPEED : 4IPS RESISTANCE : (k) 180 160 140 120 100 80 60 40 20 0 0.02 0.04 0.06 0.08 0.1 0.12 0.14 0.16 0.18 0 -20 -10 0 10 20 30 40 50 60 70 0.25 O.D 1.0 0.8 0.6 0.4 0.2 0 0.5 1 1.5 2 2.5 0.20 0.15 0.10 0.50 0 0 SLT : (ms / line) ENERGY : (mj / dot) TEMPERATURE : (C) Fig.3 Maximum energy curve Fig.4 Representative density curve Fig.5 Thermistor curve |
