If the letterpress printing machine encounters a printing failure, it will affect the normal use, so how to solve the printing failure of the letterpress printing machine?
First. The machine does not print on the right.
1. The left and right inverters alarm.
2. The machine potentiometer is faulty, replace the new potentiometer and governor.
Second. The machine does not work when semi-automatic.
1. Check the power supply.
2. Check the foot switch and start button.
3. Check whether the controller and inverter alarm.
Third. Manual and semi-automatic all do not move.
This kind of fault is that the switching power supply of the machine is burned out, and the new switching power supply is updated.
Fourth. The cylinder action slows down.
This type of failure is caused by water ingress or aging of the control solenoid valve or cylinder. A new solenoid valve or cylinder needs to be replaced.
Fifth. Automatic and semi-self-starting does not drop.
This kind of failure occurs when the proximity switch on the right side of the horizontal slide is faulty or not sensed, the selector switch is faulty, and the single-action switch interlock point is damaged. The solution is to adjust the proximity switch induction or replace the right proximity switch, replace or repair the selector switch and Single action switch.
Therefore, when the letterpress printing machine fails, it must be solved in time.
