"Motor-A has an open-circuit. There may be a loose connection, or the motor may have failed. "
HMS_0300_0600_0001_0001: Motor-A has an open circuit. There may be a loose connection, or the motor may have failed.
There are several current sensors on the MC board of the printer to sample the current of the motor, when the printer is turned on each time, the resistance of the motor will be detected through the current sensor to determine whether the motor is broken. If the resistance of motor is abnormally high, it is considered that the motor has an open circuit error.
The error that Motor-A has an open-circuit may be caused by the following reasons:
Please turn off the printer and disconnect the AC cable during operation
First please refer to this wiki to remove the rear cover of printer and check the MC board.
Motor A is the same as motor B, but motor Z is different, so if HMS reports “Motor-A/B has an open-circuit”(Assume that motor A has an open-circuit):
if HMS reports “Motor-Z has an open-circuit”,please:
