KF2003-GL50A Printheads Thick film thermal printhead (8 dots / mm) KF2003-GL50A The KF2003-GL50A 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 150 mm / s is possible without thermal history control. It is possible to print 10 inches / s or 250 mm / s if external thermal history control is used. 2) 150km life realized for GL50 by attributing durable new protection film. 3) New partial glaze construction makes it compatible with the thermal transfer application. 4) Market-proven G-series printhead construction ensures high reliability. zExternal dimensions (Units : mm) 91 6.1±0.4 (5) φ2 0 (3) Max.45 Max.36 80 (EFFECTIVE PRINT WIDTH) DOT #1 DOT #640 Max.10 #2 #20 #1 #6 Max.5.5 #1 #19 CONNECTOR A CONNECTOR B 3-M3 (EFFECTIVE DEPTH 3) 40±0.3 20±0.3 DOT #640 20±0.2 7.3±0.3 15.3±0.3 17.8±0.2 (20.8) 25±0.5 φ3H10 LENGTH 4 (EFFECTIVE DEPTH 3) 60.5±0.3 φ3H10 (EFFECTIVE DEPTH 3) 20.5±0.3 KF2003-GL50A Printheads zEquivalent circuit DOT #640 VH DOT #1 P−GND L−GND 10 9 8 7 6 5 4 3 2 1 VDD 64 OUTPUT EACH STB2 STB1 LAT LATCH REGISTER CLK SHIFT REGISTER SHIFT REGISTER DI4 DO4 DI3 DO3 DI2 DO2 DI1 DO1 TM TM SHIFT REGISTER THERMISTOR 30kΩ B: 3950 CONNECTOR DI No. DOT No. STB No. DOT No. DI1 1∼192 STB1 1∼ 320 DI2 193∼320 STB2 321∼ 640 DI3 321∼512 DI4 513∼640 Fig. 1 zPin assignments CONNECTOR A CONNECTOR B No. Circuit No. Circuit No. Circuit 1 L-GND 11 TM 1 VH 2 VDD 12 TM 2 VH 3 L-GND 13 DI3 3 VH 4 VDD 14 DO3 4 P-GND 5 STB2 15 DI2 5 P-GND 6 CLK 16 DO2 6 P-GND 7 DI4 17 N.C.
