The maintenance of the coin dispenser of the payment machine is very important.
First, clean it regularly and use a soft brush to clean the coin channel and coin slot to prevent dust, paper scraps and other foreign objects from blocking and affecting coin recognition.
Secondly, check the sensor of the coin dispenser to see if there is dirt or damage. If there is dirt, wipe it gently with a clean soft cloth; if it is damaged, replace it in time.
At the same time, check the transmission parts, such as gears, belts, etc., to ensure their normal operation and add lubricants appropriately.
In addition, the recognition function should be checked by testing the coin input to ensure that the coin denomination and authenticity can be accurately identified.
