HMS_0300_0600_0001_0002: Motor-A has a short-circuit. It may have failed.
" Motor-A has a short-circuit. It may have failed. "
when the printer is turned on each time, the motor self-check program will start and sample the current through the motor by injecting voltage. If the sample current is abnormally large, it means that the motor has a short-circuit.
The error that Motor-A has a short-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.
From the above figure, we can see the socket postions of three motors. Motor A is the same as motor B, but motor Z is different, so if HMS reports “Motor-A/B has a short-circuit”(Assume that motor A has a short-circuit):
If HMS reports “motor Z has a short-circuit”, this is usually due to the motor is broken but there is also a small probability that the MC board is broken.
