Today to share the knowledge that the wireless scanner can not be charged, which will also explain the scanning gun can not be charged, if you happen to solve the problem you are now facing, don't forget to pay attention to the site, now start!
< ul>Possible cause: Poor contact at the AC plug. The power converter (the rectifier power supply that comes with the scanner) is damaged. The power converter wire is damaged (disconnected).
The adapter may be bad, you can use everythingExcept for all possibilities: for example, try to change a USB cable, try to change the jack, try to connect to a different computer.
This is because some models of scanners have a lock, the purpose of which is to lock the mirror set to prevent vibration in transit, so the lock should be opened before turning on the scanner power switch. 2. The scanner didn't respond when it was powered up. Some models of the scanner are energy efficient, and the tube lights up only after entering the scanning interface, and automatically turns off once you exit. 3. "Scanner not Found" is displayed when scanning.
Here's the solution: Plug it in again and see what your scanner or printer showsThe light is not on. Open the Add and remove program dialog box, (double-click my computer, open the control panel, double-click Add and remove program) see if there is your scanner and printer driver, if there is, you remove it (may be the previous driver has a problem,) install again on the line, I used to use this method to solve this problem.
When the scanner is just powered on, there is a power-on self-test action, but this action needs to be completed with the driver in the computer, if there is a problem with the driver, there will be no self-test action, if it is a software problem, there should be"Image processing equipment ".
Several possibilities: The data cable is unplugged or loose. The scanners are powered down. Some scanners are powered down and the scanners still light up, but the power is insufficient. You can check it with a multimeter. Driver dropped, reinstall the driver. The USB port is broken. Try another port. If it is sisc interface, see if the card is not broken. Generally restart or reinstall the driver is good.
There are two possibilities: The power supply does notIt's plugged in so the computer can't find the device you're looking for. The driver has a problem. The solution: Plug it in again and see if the scanner or printer's display light is on.
[Fault analysis] There are two kinds of scanner faults: A. The main voltage of the switching power supply is abnormal, and B. The scanning driver circuit is abnormal. [Solution] Check the voltage at the output end of the switching power supply normally. If there are damaged components should be replaced, if repaired, the power supply voltage can be normal output power supply. If the test machine does not work, it is the drive circuit fault.
