Loosen the wheel nut and apply a little force to pull out the outer reel and ribbon core; install a new ribbon. Put the outer reel and the wheel nut back into the shaft in turn to make contact with the damper disc.
The ribbon is wound in the order of the red line of the structure diagram, and finally the sticker is attached to the empty paper tube in (6). When installing the ribbon, be sure to turn the ribbon surface toward the center of the shaft and roller. When the ribbon passes between (27) and (28), the compression (4) should be pulled upwards to make (28) slightly away (27). After the ribbon has passed, release (4), (28) resets itself under the action of a spring.
The position of the plastic outer retaining ring on the belt guide shaft should be adjusted so that the distance between the two retaining rings is about 1 mm wider than the ribbon.
Depending on the thickness of the printed matter, the length of (9) should be adjusted accordingly. At this point, the two nuts of the double-headed screw of the connecting rod should be loosened. Since the thread of the double-headed screw is left-handed and right-handed, the length of the connecting rod can be changed by simply pulling the hexagonal column of the screw. The correct length of the connecting rod should be such that when the head is at the lowest position, the movable type is 0.5 lower than the highest point of the material to be printed. To do this, place the printed object on the rubber plate and turn it with the Allen key (8) to the bottom dead center position. At this time, when the hexagonal column of the double-headed screw is pulled to make the printed object by hand, there is a slight resistance, indicating that the gap between the movable type and the printed matter is substantially eliminated. At this time, in the direction of the extension of the connecting rod, the third to fourth ribs of the hexagonal column are pulled, and then the nut is locked.
Note: Changes in link length can affect the printing pressure. If the pressure is too high, the printing ribbon will be broken and the printed material will be crushed; if the pressure is too low, the printing will be unclear. Therefore, the operator must pay attention to the length adjustment of the connecting rod.
When (25) reciprocates once, (27) is turned counterclockwise by an angle by a (19) fixed to the right angle bracket, (17) and a one-way motion mechanism, thus driving the ribbon to a distance, the distance Called the step size. If the step size is too large, the ribbon is wasted and the step size is too small, resulting in unclear printing. The optimal step size should be 1 mm larger than the total height of the word column.
In order to adjust the ribbon step, the butterfly nut of (20) should be loosened. The upward movement can reduce the step size, and the downward movement increases the step distance. After adjusting, the wing nut should be tightened.
When the temperature adjustment knob is turned clockwise, the temperature rises; when turned counterclockwise, the temperature decreases.
The machine warm-up time is about 15-20 minutes. If it is used urgently, the temperature can be adjusted to the maximum value. After the temperature is reached, the temperature can be adjusted back to the original position to shorten the warm-up time.
Note: Since the machine adopts the principle of time temperature control and is affected by material properties, thickness, environment and other factors, the optimum temperature should be confirmed according to the printing effect.
This machine can choose two control methods: “continuous” or “speed control”. When the control switch is turned to the left to "speed control", the machine is controlled by the foot switch, and the operator pedals once, then the printer prints once.
When the control switch is turned to the right to "continuous", the machine automatically prints, that is, prints once every interval, and repeats. The speed knob on the control panel is used to adjust the print speed. Turn clockwise and speed up; turn counterclockwise and slow down. With the rotation of the speed knob, we can arbitrarily choose the print speed between 10-100 beats/min.
When the printer is in the printing process, the life word and the printed matter are stuck or other emergency abnormal conditions, press the "emergency rise" button, the printer motor will immediately reverse, which will drive the print head back to the top dead center position. The card can be taken out and the work can be resumed after the fault is removed.
Use of the "Check" button. When debugging the ribbon step, printing effect and debugging the machine, you can use the "foot" control, so that the code machine can be jogged, but you can generally press the "check" button and press it. The code machine can also be used once, which is often more convenient.
Push the print head handle (1.5-2mm) inward and turn the handle 90°-180°. Disengage the hook head, pull out the print head, loosen the fixing screws on the movable seat, replace (26), the installation should be high and low, not skewed, and then installed in the reverse order. Do not hit with a metal rod (26) to avoid damage.
The printing machine is not clear, what is the cause?
1.The temperature is too low, the warm-up time is insufficient, and the warm-up time needs to be lengthened.
2.The connecting rod is not properly adjusted, and the connecting rod needs to be adjusted to increase the pressure.
