How to solve the failure connection of the piezoelectric printer? Fedar piezoelectric printer manufacturers share several possible causes and solutions for your reference.
 
1. Software error
Solution: Reinstall the fedar printer driver software.
2. The piezoelectric printer driver is not recognized
Solution: Open the device manager and check whether the USB is recognized normally.
3. The origin switch is damaged
Solution: Push the piezoelectric printer car to the middle of the printing panel and turn it on. If the car moves to the left, the origin sensor may be broken; if the car moves to the right and hits the right baffle, it is necessary to check whether the position of the carriage stopper can be inserted into the origin sensor or the origin sensor is broken.
4. The motor and motor drive board are damaged
Solution: Push the car to the middle of the printing panel and start it. If the car does not move, block the origin sensor with a card. If it can be connected, it may be a problem of the motor and the motor drive board.
5. Computer system failure
Solution: Replace the computer or reinstall the computer system.
6. Main board failure
Solution: Replace the fedar piezoelectric printer main board.
