KF2004-GM50

KF2004-GM50A Printheads Thick film thermal printhead (with thermal historical control) KF2004-GM50A GM50 series is the new product that newly added the future history control and driver LSI which has the function of thermal historical control, to GL50 series which is employing the convertional thick-film fast response thermal element. !Applications High speed label printer High speed bar code printer High speed ticket printer Various high speed terminal printers !Features 1) Newly developed thick-film fast response thermal element and driver LSI with the function of thermal history control which is added the future history control are employed for this series. It is possible to print with super high speed of 10 inches / s or 250mm / s. 2) 150km life realized 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. !External dimensions (Units : mm) LABEL 118 104 (Effective Print Width) (7) 3-M3 (Effective Depth 3) 6.1±0.4 (5) 80±0.3 12±0.2 40±0.3 (19) Dot #832 Dot #1 95±0.3 15±0.3 Max.45 Max.36 φ2 0 25±0.5 (20.8) (3) 15.3±0.3 Max.12 Max.5.5 φ3H10 Length 4 (Effective Depth 3) φ3H10 (Effective Depth 3) #2 #20 #6 #1 #1 CONNECTOR A #19 CONNECTOR B 17.8±0.2 7.3±0.3 KF2004-GM50A Printheads !Equivalent circuit VH (COM) 100µF×2 35V DOT #832 DOT #1 GND 0.1µF 50V VDD (+5) / STB2 / STB1 / RESET LATCH REGISTER CLKIN2 DI2 DO2 CLKOUT2 CLKIN1 DI1 DO1 / LOAD START INC SEL2 SEL1 TM TM THERMISTER 30kΩ B: 3950 TO EACH IC DI, STB DIVISION DOT No. CORRESPONDENCE DI No. DI2 DI1 DOT No. 832 ∼ 449 448 ∼ 1 / STB No. / STB2 / STB1 DOT No. 832 ∼ 449 448 ∼ 1 CLK No. CLKIN2 CLKIN1 DOT No. 832 ∼ 449 448 ∼ 1 KF2004-GM50A Printheads !Pin assignments 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 (COM) VH (COM) VH (COM) VDD VDD SEL2 SEL1 CLKIN2 (CP) NC DI2 DI1 INC / LOAD 11 12 13 14 15 16 17 18 19 20 / RESET START DO1 DO2 TM TM / STB2 / STB1 CLKOUT2 CLKIN1 GND GND GND !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 104 0.125 832 550 24 0.857 0.490 0.258 832 8 φ20.0 150/(1×10 ) 8 Unit mm mm dots Ω V W/dot ms ms dots MHz mm km/pulses °C 5~45 !Data sheets 1.6 1.4 SLT : 0.82ms / line 1.0 0.9 Level1 Level2 Level3 MAXIMUM ENERGY (mJ/dot) 0.8 0.7 0.6 0.5 OPTICAL DENSITY 1.2 1.0 0.8 0.6 0.4 0.2 0 0.00 0.05 0.10 0.15 0.20 0.25 0.30 0.35 0.40 ENERGY (mJ/dot) Level4 0.4 0.3 Level5 Level6 0.2 0.1 0.0 0 0.2 0.4 0.6 0.8 1.0 1.2 1.4 SCANNING LINE TIME (ms/line) Fig.2 Representative density curve Fig.3 Maximum energy curve
