One of the most important things about maintaining a cash machine is dust removal. In humid areas, if the dust accumulation is more, it will have a great impact on the power of the machine. In dry regions, the dust with a large number of free charge, and bundle of printing machine in the process of bundle of money also can produce a part of free charge, this will result in free charge accumulation on money, eventually produce point discharge, namely "static". The electrostatic discharge phenomenon will affect the machine, the light will affect the fake, and the heavy will cause irreparable damage to the integrated circuit of the machine. Regardless of these adverse effects on the machine, dust is also harmful to the human body. So the most important task of maintaining a machine is to remove dust.

       The place where dust accumulates more in the machine is ultraviolet lamp tube. Ultraviolet lamp tube is a kind of light source which USES optical technology to detect and fake it. When it is shielded, the intensity of the light source will be decreased, so the sensitivity of the detector will also be reduced. In most cases, the optical sensor is very close to the light source, and if the tube is more dusty, it will also cover the sensor, so the sensitivity of the detector is lower. The dust here can be cleaned with a brush or a cloth, but it is important to remember that you must first pull the power cord out of the machine to avoid electric shock! After cleaning the dust on the lamp tube, we will clean up the dust box of the machine. The vacuum machine with the dust collection device, the dust collected by the dust collection device is installed in the dust box, which can be removed and cleaned. The mechanism of the machine is very complicated. Do not touch the machine with brush or cloth, or it will damage the machine easily.

       The vulnerable parts of the banding machine mainly include the rubber device and the ultraviolet lamp tube. The money machine is a machine that imitates the human banknote. It mainly imitates friction, so it USES some rubber parts. After a period of time, the friction of the rubber device will decrease due to wear, and thus the performance of the machine will be reduced. In this case, the corresponding rubber device needs to be replaced. In addition, uv light emission capability is also reduced after a period of work, which results in a decrease in the machine detection ability, which also requires the replacement of ultraviolet lamp tube. It is generally easy to change their methods, so long as the corresponding parts are removed by the method required by the instruction manual, and then the new device will be installed.
