What Does JACK A4B Err-06 Mean for the Electromagnet Circuit?
Exact model: JACK A4B-A/C
Safety: Disconnect mains before clearing thread or checking motor/solenoid connections.
A.
Start with the accessible checks
What this suggests: On the matched JACK A4B RA6 table, Err-06 concerns an electromagnet/solenoid output.
What to do
- Disconnect power and manually inspect the corresponding lever/solenoid mechanism for thread wraps, binding and broken return springs.
- Clear the mechanical jam and restore a loose plug or crushed harness at the specified actuator.
Still not fixed? Continue to the next check.

If the problem remains after the first checks
What this suggests: Link it to the operation being attempted: thread trimming, reverse feed or presser lift.
What to do
- If the same operation still produces Err-06 with free movement, qualified personnel should inspect the correct coil and output drive and replace the diagnosed matching solenoid, not an unrelated actuator.
Confirm the repair
The selected trimming/reverse/lift action completes without binding or Err-06, and normal stitching remains synchronized.
