Guangzhou State Association, state licensing 118 supermarket cash register, silver machine provided by the Guangzhou State Association. We are Guangzhou City State Association Information Technology Co., Ltd. (www.gzdb899.com) located: Guangzhou specializes in: cash register, scanner, bar code machines, management software, small ticket machines, cash registers, cash registers shredders Troubleshooting principle cash registers as high reliability products Easy Exhibitor K2000 supermarket POS cash register, 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, when the POS machine failure, should be based on "first soft and hard, the outside after the first," "the principle of fault determination and exclude state licensing 138 super silver machines, specifically that: (1) First check the system software, application software if there is a problem (2) Inspection 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 the fault alternative silver machine, which precludes the using the normal equipment of various suspicious components. (example: test network cable, network cable can be used to test whether the normal equipment of normal) (4) device hardware failure (failure especially in the power section, emitting a smell or significantly abnormal sound), first Check off only apparent reason to exclude all possible (short, burned parts, etc.), in order to power-examination. (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. supermarket cash registers to buy standard supermarket to buy cash registers, when a number of factors need to be considered from the state licensing 118 supermarket cash register, such as supermarket time scale, product number, etc., cash registers are generally two types of what we often say that electronic cash registers, so when selecting a specific device, even if the same grade of equipment is still a great choice of Van, we have chosen One should be cautious standards, from a hardware point of view must choose the performance and high reliability devices, currently used by more brands on the market are: Kawasaki ECR POS cash registers and LEADER, provides a standard interface. Since most of the cash register is split combination, so the display is relatively easy. standard two, from a software point of view we must choose a simple and reliable system drivers can be secondary development of the device, the driver or the driver command the bottom as possible. standard three, brand and quality is an issue that must be considered, brand name is obtained through a variety of tests and obtained through the actual test, but higher brand-name prices. standard four, technical service support is also an important choice standard, when cash registers failure to get timely maintenance, to ensure that users will not suffer losses due to machine failure. standard five, according to the needs of the system for equipment selection, we must ensure that the introduction of cash registers can indeed strengthen management, enabling managers to work out from the complex out and give more consideration to how to run a benefit.
