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) 65 (4.5) DOT #448 56 (EFFECTIVE PRINT WIDTH) DOT #1 6.1±0.4 (5) Max.45 Max.36 (3) #2 #20 #4 #1 Max.5.5 φ20 Max.10 #19 #1 CONNECTOR A CONNECTOR B 3-M3 (EFFECTIVE DEPTH 3) φ3H10 LENGTH 4 DOT #448 0±0.2 (EFFECTIVE DEPTH 3) 55.5±0.3 55±0.3 25±0.5 (20.8) 7.3±0.3 15.3±0.3 28±0.3 56±0.3 φ3H10 (EFFECTIVE DEPTH 3) 17.8±0.2 KF2002-GL50A Printheads zEquivalent circuit VH P−GND L−GND 7 6 5 4 3 2 1 DOT #448 DOT #1 VDD 64 OUTPUT EACH STB2 STB1 LAT LATCH REGISTER CLK SHIFT REGISTER SHIFT REGISTER DI2 DO2 DI1 DO1 TM TM CONNECTOR THERMISTOR 30kΩ B: 3950 DI No. DI1 DI2 DOT No. 1∼ 192 193∼ 448 STB No. STB1 STB2 DOT No. 1∼ 192 193∼ 448 Fig. 1 zPin assignments CONNECTOR A No. 1 2 3 4 5 6 7 8 9 10 Circuit No. Circuit CONNECTOR B No. 1 2 3 4 Circuit VH VH L-GND VDD L-GND VDD STB2 11 12 13 14 15 16 17 18 19 20 TM TM DI1 DO1 N.C.
