How to troubleshoot POS cash register failure
Touching the POS cash register as a high-reliability product has a low probability of failure. However, due to external power supply changes or external environmental changes, product failure may also result in hardware failure due to serious collisions during transportation, but the hardware itself is still less faulty. Therefore, when the POS cash register system is faulty, the fault should be judged and eliminated according to the principle of “soft first, then hard first, then first inside and outsideâ€, specifically:
(1) First check whether there is a problem with the system software or application software;
(2) Verify that the external cable is connected correctly and the external device is normal (if the network is unreachable, check whether the network cable is normal and the switch is normal);
(3) When determining the fault, an alternative method should be used, that is, normal equipment is used to eliminate various suspicious components. (For example, if the test cable is used, the normal device can be used to test whether the network cable is normal);
(4) When a hardware failure occurs in the equipment (special power supply failure, odor or obvious abnormal noise), the power should be checked first. Only after eliminating various possible obvious causes (short circuit, burnt parts, etc.) can power up. an examination;
(5) When determining the host interface or peripheral failure, run the check.exe test provided randomly under pure dos;
(6) Test keyboard port equipment should be carried out under pure dos.
The printer does not print
(1) Check that the printer cable is properly connected and the power is normal.
(2) Check if the printer status is normal and there is no paper or paper jam.
(3) It is normal to replace the printer test or connect the printer to other machines.
(4) Test whether the printing is normal in CHECK and determine whether to apply a software error.
Printer characters are blurred or missing strokes
(1) The ribbon has no color and the ribbon is replaced.
(2) The print head breaks or the print head cable breaks.
(3) The needle printer has two-way printing positioning offset, and the belt is loose.
(4) Print the ticket character offset.
A malfunction caused by a bad head cable.
The printer cannot self-test; it does not stop feeding, does not feed paper; the printing is interrupted; the printing is unclear, less lines, and ghosting.
A malfunction caused by severe wear of the main transmission gear of the printer.

How to deal with the display darkening after using one stage
(1) Check if the monitor signal line is loose.
(2) Make sure that the display power indicator and the host power indicator are normal.
(3) Adjust the brightness of the display, and make sure that the touch POS cash register is not in the sleep state.
(4) Replace the display and pay the manufacturer for repair.
The guest is not bright
(1) Make sure the communication cable is wired correctly and securely, check that the power settings are correct or the output is normal.
(2) Run CHECK, test whether the customer is correct, replace the serial port test is correct, determine whether the serial port is wrong.
(3) Open the monitor to check if the air vent of the VFD screen is broken.
How to open a stuck cash box
If it is caused by too much money, use a thinner ruler to gently push in the money and then open the cash box.
Money box pops up without power
(1) After using for a period of time, lubricating oil may be added due to insufficient lubricating oil and increased friction.
(2) The pulse width of the open cash box is insufficient (the delay is insufficient).
(3) The spring or the crank arm that pushes the cash box is insufficiently elastic.
Emergency treatment after the keyboard is flooded
(1) Quickly remove the keyboard.
(2) Turn the keyboard over and try to pour out the liquid inside.
(3) Open the keyboard case screw and blow it against the surface of the circuit board and the key body with a blower to dry the water.
(4) Install the screws and leave the keyboard for 24 hours (preferably in a ventilated area).
