Dot Matrix Printer Mechanism IP1 Series thermal printers The IP1 printer has the following character: long life, high reliability and high print resolution. It usually used on ECR, fiscal cash register, etc. IP1 Features 鈼咮idirectional printing 鈼咹igh speed 鈼咹igh reliability 鈼咮lack mark director 鈼哖aper width:58mm and 76mm 鈼唌ultipe copy Specifications ITEM: IP1 Printing method: Impact dot matrix Printing width: 4.4 lines/s (42 English characters per line) 5.6 lines/s (30 English characters per line) 8.9 lines/s (15 English characters per line) Paper feed speed: 13.9 mm/s or 33 lines/s (line heigth: 4.23mm) Dot pitch(mm): 0.355 Printing dots: 210 totally, can print 420 places Paper width: 58 or 76 Printer moving resolution (mm): 0.3024 Paper feed resolution (mm): 0.176 Dimension (mm): 127x98.2x53 Weight (g): 470 Head temperature detection: thermistor Paper detection: Photo-sensor In place detection: Photo-sensor Black mark detection: Photo-sensor Color bar: ERC-39 Connecting lines: 1.25 mm 27PIN FCC or FPC Totally width:35 mm, thickness:0.3 mm Mechanism life: 9 million lines Printer head life: 3 hundred million dots/ needle Operation voltage range(V): 24V卤10% Logical voltage(V): 5.0卤5% Operating temperature(掳C): 0锛?0 Operating humidity(RH): 10锛咃紞90锛?/p Storage temperature(掳C): 5锛?5 Storage humidity(RH): 40锛咃紞70锛?/p Thermal Print head configuration Dots of line: 9 needles, vertical distribution Needle circle resistance: 18.7卤10%惟 Dot pitch: 0.355 mm Operation voltage range(V): 24V卤10% Logical voltage(V): 5V卤5% Printer head life: 3 hundred million dots/needle 1.1 Energy consumption Drive conditionspecification 1Standard conditions: e24V,room temperature6.9mJ/dot Drive width 346碌s 2Max. energy consumption 26.4V, 0鈩?/span16.1mJ/dot Drive width 322碌s 3Performance calculationInput energyJ* printing dot/ dirve time (s) 4The average energy consumption to print the following K character33.4W e脳18dot/(0.413ms脳9) 5Peak current11.7A锛?/spanstandard condition锛?/span 15.3A锛?/spanmax锛?/span Note: drive voltage will be not higher than 21.6V. 1.1 Characters Itemcodeconditionnumberunit inputForward voltageVFIF=10mA-1.21.6V Reverse forward voltageIRVR=5V 10碌A wavelength位PIF=10mA 940 Nm outputCollector to emission voltageBVCEOIC=0.5mA30 V Emission to collector voltageBVECOIE=0.1mA5 V Collector dark currentICEOEe=0mW/cm2 VCE=20V 1碌A Collector light currentILVCE=5V IF=10mA RL=1K1.52 mA Saturation voltage dropVCE(SAT)IF=10mA IC=0.1mA 0.4V Coupling characterRise timetrVCE=5V IC=2mA RL=100惟 5 碌s Fall timetf 5 碌s 1.1 Stepper motor phase Step number place1234 A--++ B+--+ /A++-- /B-++- If you use half step, there are 8 places (from right to left). Step number place12345678 A--- +++ B+ --- ++ /A+++ --- /B- +++ -- Power on A and B coils, use 66% current drive to reduce heating when half step drive. You are advised to use 100% current drive during speeding up to increase power. 1.1 stepper motor drive 1, Use PWM way to advoid motor over heating. you can choose chips: L6219,L2916,L3967 or others; 2, motor should move 24 steps at least to avoid the color bar destroy when printing as the color bar is also drive by printer head. 3, the motor drive should be finished according to HOME place detection. When it is in HOME, the step motor allowed to move 27 steps toward the right, 228 steps toward to left. 4, the motor drive should be slow stared and stopped.
