KD2004-DC10A Printheads Thick film thermal printhead (8 dots / mm) KD2004-DC10A The KD2004-DC10A is a 24 V standard thick film thermal printhead with a printing speed up to 6 inches / s that has been developed mainly for label printer use. zApplications High speed label printer High speed bar code printer High speed ticket printer Various high speed terminal printers zFeatures 1) Newly developed thick-film fast response thermal element is employed for this series and 6 inches / s or 150mm / s is possible without thermal history control. It is possible to print 10 inches / s or 250mm / s if external thermal history control is used. 2) 150km life realized by attributing durable new protection film. 3) New partial glaze construction makes it compatible with the thermal transfer application. zExternal dimensions (Unit : mm) 6.1±0.4 (5) 118 104 (EFFECTIVE PRINT WIDTH) DOT #1 DOT #832 + Ma + x.φ 20 Max.45 Max.36 (3) (7) Max.10 #2 #20 #1 #6 #1 Max.5.5 #19 CONNECTOR A CONNECTOR B 3-M3 (EFFECTIVE DEPTH 3) (19) 80±0.3 12±0.2 40±0.3 15±0.3 φ3H10 LENGTH 4 (EFFECTIVE DEPTH 3) 17.8±0.2 15.3±0.3 7.3±0.3 (20.8) 25±0.5 95±0.3 φ3H10 (EFFECTIVE DEPTH 3) 1/3 KD2004-DC10A Printheads zEquivalent circuits DOT #832 VH DOT #1 VSF L/S #832 GND #641 #640 #449 #448 #257 #256 #1 VDD STB4 STB3 STB2 STB1 /LAT LATCH REGISTER CLK SHIFT REGISTER SHIFT REGISTER SHIFT REGISTER SHIFT REGISTER DI4 DO4 DI3 DO3 DI2 DO2 DI1 DO1 TM THERMISTOR 30kΩ B : 3950K TM CONNECTOR VSF : Usually VSF and VH are connected.
