Whether the printer works normally or not, the quality of the motor plays a very important role. The long life of the motor is not easy to damage, so we must first determine whether the motor is damaged before replacing the motor, such as removing the boot cover and observing whether the motor rotates, because of the damage of the transmission belt and the problem of gear engagement, the failure of the car and the paper feed can also occur.


If the problem is determined by the motor, the motor can be replaced according to the following steps:

1. Disconnect the power supply and use a screwdriver to remove the cover of the printer.
2. Remove the connection cable of the motor. Before unplugging the connection cable, you must remember where it was originally connected. Otherwise, the wrong interface will burn the motor and cause damage to the main board.
3. Take off the transmission belt, pay attention to the process, and do not damage the motor with too much force.
4. Remove the old motor and install the new one.


The installation process must be noted that the whole process can be completed with a screwdriver. You cannot use a hammer or the like to strike, because the photo machine is a precision device, and it may cause damage to the piezoelectric printer.
