Handheld scanner common problems and solutions

With the advent of the informatization period, major industries are willing to introduce more high-end equipment for more efficient management and work. We know that handheld scanners usually refer to keyboards or operators with cable connections. Then we will encounter many problems in the process of application. Generally, we will have a description book in what we buy, but there are also many friends who watch it. I don't understand, or do not elaborate on the common problems and maintenance methods of handheld devices.

Let's start with an introduction to the handheld scanner. The handheld scanner refers to a portable data processing terminal with the following features: an operating system such as WINDOWS Mobile6.1/6.5 WinCE5.0/6.0, LINUX, Android, etc.; memory, CPU, graphics card, etc.; screen and keyboard: data transmission disposal; itself has a battery, can be moved. Handheld scanners are generally classified into industrial-grade handheld terminals and consumer handheld terminals. Industrial-grade handheld terminals are better at performance, stability, and battery durability than consumer.

What problems will you encounter after using the equipment? Let me explain the following ten points:

First, the device can not be turned on, what should I do?

Check if the battery is installed correctly, and whether the battery back cover can be completely covered; please check if the battery has power; if the battery has electricity and the correct device battery, please do a cooling operation (FN key + reset button); Charge the battery for 10 minutes and try to turn it on again.

Second, during the scanning process, the scanning head emits light but the barcode is not recognized, and the system is very stuck when scanning. What should I do?

Recalibrate the scan head. Operation method: Double-click "Scanner" on the desktop, open the scan head, reset the scan head, and reset the victory; please confirm whether the scanned barcode is intact or not; if the scan head is recalibrated, and confirm If the barcode is not damaged, you can restart the device.

Third, can't connect to the WIFI network?

First check whether the encryption method is correct, that is, check whether the encryption mode of the handheld device and the local network are different; check whether the password is correct; check whether the network is normal; restart the device or delete the network and reconnect (network configuration after wireless configuration) Select the interface advanced, delete the network you want to delete in the list box of the preferred network, press the affirmative button to complete the operation)

Fourth, can't connect to the GPRS network?

Check the local signal strength; check whether the SIM card can be installed correctly; check whether the SIM card can open the Internet function; whether the access point can be set correctly; check whether the SIM card can be owed or the SIM card can be damaged (SIM card is installed to stop the phone) Can the test be damaged or owed).

Fifth, the wireless network automatically disappears after startup, what should I do?

After the wireless is enabled, the status bar displays the network icon, but it disappears automatically after two seconds. Don't worry, you can see the wireless network connection as a cross mark in the "Start - Settings - Network Connection", view the properties, set it to Enable it.

Then, the common problems and maintenance methods for using handheld terminal equipment are explained here, and the comparison is clear. I hope I can help you. In fact, when we are consuming consumer terminal devices, we must also look at whether manufacturers can be professional, whether the quality of production can pass, and after-sales service, then we can consult after-sales service without knowing.
