POS cash registers troubleshooting principles as high reliability products, the lower the probability of its failure. However, due to changes in the external power supply or external environmental changes caused by product failure, may also be because of a serious collision handling, causing hardware failure, but the situation is the failure of the hardware itself is still relatively small. Therefore silver machines, POS machines when failure should be based on "first soft and hard, the outside after the first" "fault determination and the principle of exclusion, specifically that: (1) First check the system software, application software if there is a problem ( 2) test outreach cable is connected properly, the external device is correct (if the network fails, check network cable is normal, the switch is normal) (3) should be used to determine faults alternative, which precludes the use of a variety of suspicious components normal equipment (eg: Test the network cable, network cable can be used to test whether the normal equipment of normal) (4) device hardware failure (failure especially in the power supply section 128 state licensing silver machine, emitting a smell or significantly abnormal sound), first off electrical inspection, only the exclusion of all possible apparent reason (short circuit burned parts, etc.), in order to increase the electrical inspection. (5) determine the host interface or peripheral fault, CHECK.EXE test run should be run in pure dos. (6) Test the keyboard port equipment should be carried out under pure dos.
