Fault one: The machine is running normally. After printing a paper, it stops. After washing blankets, paper, and then turning on the machine, feeder automatically raises the paper without raising it. It was normal, but suddenly a sudden failure occurred. Check that the electromagnet is not burned and the line is not broken. According to an inspection by an electrician, the original relay with 36V and 5A had loose screws and the fault was eliminated.
Fault 2 : The paper is sloping and the skewed paper is taken out. Feida is reopened and the paper is fed, but it is not pressed. Open the shield and check that the electromagnet wiring is not broken. Obtain an electrician and check the electrical wiring and electrical components of the electrical box. No problems are found. After measuring the current voltage plate, it was found that a voltage plate was too low, hands-on adjustment, and normal pressure.
Fault 3: Parking after washing the blanket, and then boot, the machine does not run, the positive and negative points can move. Turn on the motor without turning, check the fuse and found no problem. Check the button and its line and found no abnormality. Continue to check the electrical box, after measuring the original AC contactor is broken, replace the troubleshooting.
The common feature of the above three cases of faults is the coincidence failure of the machine due to temporary suspension of printing under normal conditions. The difference is that the first case is a hidden fault, that is, the relay screws may have loosened, and in the case of a non-connected case, poor contact due to repeated vibration. The second example is the concurrency failure, that is, the paper is skewed, the paper shape is mutated, and the front gauge voltage sheet is too low. When the power is turned on again, the paper cannot be in place and the voltage chip cannot break away from the contact and form a fault. The third example is the coincidence of electrical damage.
