During these days,we are talk aobut some information about the Man Roland Parts,we know that the Circuit maintenance is also an important part of printing machine maintenance. We can divided it into four parts: the components detection, control components, drive circuit, actuators,Circuit wiring.
Detecting element is used to detect the status of the printer. Detection device including the safety switch, stop pin switch, protection switch dangerous parts. Detecting element also includes some running status detection switch, such as gauge before magic eye detection, magnetic reed switch, the misdiagnosis of these switchs or not work, may cause the machine can not operation normally.
Control element is used to control the drive circuit, but its signal comes from the detecting element,the signal control circuit accepted must be normal, otherwise it may cause error action, or will damage the circuit, thus the requirement of the anti-interference is strict for the control circuit,it is better to add the noise filter to the sensitive components,or use the special materials to block it up.
Driver circuit are generally high power components, its fever is big, so cooling is an important part of the maintenance for these components. If the motor fan stalling is dangerous, the motor is covered by the paper or other objects, can also cause the damage of the motor.
Actuator Belongs to the mechanical loop, such as motor rotor, etc. If the mechanical circuit is uneven, the drive energy of the circuit can't work, and can only be converted to heat, makes the temperature rise sharply, causing damage of the motor. So must ensure the machinery smooth all the time.
Circuit wiring must be carefully considered: one is to prevent the collision of mechanical parts, cause a cutting-out or disconnection, so you should put it in place. Second, cables should be protected careful, prevent its surface aging, such as using the snakeskin tube, etc.What's more,you should try to avoid oil droping onto the wire. In addition, also should pay attention to the line interface fracture due to vibration.
