Because of the large amount of people used in automatic lockers, various types of failures often occur. In the automatic locker can not print bar code paper or button is not normal, you need to check the printer for paper jam or out of paper. When the button is pressed, it can be observed whether the button lamp is lit.
Finally, you need to check the scanner port for dust. If it is, it may cause the barcode paper to not be scanned properly. If the barcode paper cannot be scanned, open the chassis to see if the position of the internal scan panel is deviated and adjust it so that it is in a normal state.
