have a good day
concern Error E004 can you please tell me the control Box model? generally E004 means:
1-Synchronizer lower position sensor failure ( SC-500 / SC-510 )
cause :
======
• When position detection signal is not input from the sewing machine head synchronizer.
• When the synchronizer has broken.
points check:
==========
• Check the synchronizer connector (CN33) for
loose connection and disconnection.
• Check whether the synchronizer cord has broken
since the cord is caught in the machine head.
otherwise make sure first connection for synchronizer connected securely.
