How to deal with problems after using supermarket cash register

The cash register is a must-have commercial machine for every supermarket. After the supermarket has finished shopping, it goes to the cash register area to pay. The machine operated by the cashier is the cash register. , People feel depressed.

What are the common problems encountered in supermarket cash registers? How to deal with it? The following editors will talk to you.

1. The cash register of the supermarket crashes when working

(1) Judgment: Usually, the cash register stops at a position when it is working normally, and no response can be made when the keyboard is tapped. At this time, it can be judged that the machine is dead.

(2) Causes of failure: There are many reasons for the crash. Overheating of the chip and other major components can cause the crash.

(3) Inspection method: first check whether the power supply fan and chip fan are operating normally. If the speed is too low, it can be determined that the chip or power supply temperature is too high and the cash register crashes; then the equipment must be replaced one by one for testing.

2. The cash register is in a stand-alone state

(1) Judgment: Generally, when the cash register fails to connect to the F disk when it is working, it cannot connect to the server, and when the cash collection program is displayed as a single machine, it can be determined that the cash register is in a single machine state.

(2) Failure reason: host failure, network failure, background failure.

(3) Checking method: First of all, it is necessary to determine the point of failure. When the cash register is stand-alone, the network cable of the cash register can be exchanged with other cash registers that can be networked normally. If it can be networked, it can be determined as a non-host failure. For non-host failures, you can exchange the network cable interface of the machine on the HUB with the network cable interface of other cash registers that are normally connected to the network. For example, after the exchange, the normal host computer and network cable can be networked, but the problematic host computer and network cable can not be networked. It is determined that the network cable is faulty. If the network can be connected after replacement, it can be determined that the network cable port is loose; if the normal host and the network cable cannot be networked after the exchange, and the problematic host can be networked, the network cable socket can be determined to be faulty.

3. Printer jam in supermarket cash register

(1) Judgment: After the printer is connected to power, the printing paper cannot enter the paper path normally and the ERROR red light on the control board lights up, it can be judged that the printer is jammed.

(2) Failure reason: there are debris in the paper path and the sensor is damaged.

(3) Inspection method: turn the printer over and pat the bottom, then try again after debris is poured out. If the paper still cannot be fed normally, it needs to be repaired. Note Put the paper on the side of the roll paper gently before putting the paper in the paper path, and then use it after handling some debris (the debris may affect the paper feed, wear gears, etc.).
