| KF2008-GK11A Printheads Thick Film Thermal Printhead (8dots / mm) KF2008-GK11A The KF2008-GK11A use a high durability protective film to accept top coated label sheet. This is a light and small thick film type thermal printhead which achieved 1 inch / s printing speed. !Applications POS terminal printers Label printers CAT printers General purpose compact printers !Features 1) A high durability protective film has been developed newly as a counter measure against static electricity. 2) The clip connector for the FFC specifications has been developed newly using an original technology thereby making it possible to achieve even smaller size. 3) A newly developed 144-bits IC levels the strobe partition and reduces the noise level. 4) One rank resistance value of 15003% eliminates the inconvenience of rank selection. !External dimensions (Units : mm) 230.50.3(HEATSINK WIDTH) Max. 1.7 230(SUBSTRATE WIDTH) (5.1) DOT #1 0 ax . 20 . 2.60.1 216(EFFECTIVE PRINT WIDTH) DOT #1728 Max. 18.0 No.28 No.1 M Max. 10.5 (Open) (ROCK) 36.250.1 33.750.1 0.80.03 1.250.05 0.30.05 5.10.2 2-M3 EFFECTIVE DEPTH3 50.2 220.50.2 Diagrams of appropriate cable for reference(2 / 1) 7 Dimensions of reinforcing panel Min. 4 KF2008-GK11A Printheads !Equivalent circuit 144 OUTPUTS EACH VH GND DOT #1728 DOT #1 12 STB4 STB3 STB2 STB1 11 10 9 8 7 6 5 4 3 2 1 LAT CLK DI1 DO1 DI2 DO2 VDD TM TM CONNECTOR LATCH REGISTER LATCH REGISTER SHIFT REGISTER SHIFT REGISTER THERMISTOR 30k B:3950 Fig. 1 !Pin configuration No. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 Circuit VH VH VH DO2 DI2 CLK LAT STB1 STB2 TM GND GND GND GND No. 15 16 17 18 19 20 21 22 23 24 25 26 27 28 Circuit GND GND GND GND TM VDD STB3 STB4 DO1 DI1 VH VH VH VH KF2008-GK11A Printheads !Timing chart tw CLK CLOCK(CLK) t setup DI DATA IN(DI) High : BLACK Low : WHITE td DO DATA OUT(DO) High : BLACK Low : WHITE t hold DI t setup LAT LATCH(LAT) High : HOLD Low : THROUGH t hold LAT tw LAT t setup STB STROBE(STB) tdo DRIVER OUT tdo 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 - - - - - Typical 216.0 0.125 1728 1500 24.0 0.30 5.0 0.80 432 4 14.0 50 / 5x10 545 7 Unit mm mm dots V W / dot ms ms dots MHz mm km / pulses C KF2008-GK11A Printheads !Data sheet 0.5 0.45 0.4 1.4 1.2 OPTICAL DENSITY SLT : 10ms / line 1 0.9 0.8 ENERGY(mJ / dot) 1 0.8 0.6 0.4 0.2 0 ENERGY(mJ / dot) 0.35 0.3 0.25 0.2 0.15 0.1 0.05 0 4 6 8 10 12 14 16 18 20 22 0.7 0.6 0.5 0.4 0.3 0.2 0.1 0.1 0.2 0.3 0.4 0.5 0 0 5 10 15 20 SCANNING LINE TIME(ms / line) ENERGY(mJ / dot) SCANNING LINE TIME6.5 Fig. 3 Adaptive speed chart Fig. 4 Representative density curve Fig. 5 Maximum energy curve 180 160 140 RESISTANCE : (k) 120 100 80 60 40 20 0 -20 -10 0 10 20 30 40 50 60 70 TEMPERATURE : (C) Fig. 6 Thermistor curve |
