Fault Cause
1. XY axis idling speed is too fast
when stopping
2. The trimming module or power
board is broken.
1. Poor contact of motor seat
2. The motor wire is disconnected
or damaged
3. The thread trimming module is
broken

Solution
Cause of failure
When retrieving the origin of the inter-
mediate presser, the sewing machine al-
ways runs to lift the intermediate presser
and read its origin. If you intentionally
lift the intermediate presser by hand, an
error may be caused since the interme-
diate presser interferes with the bushing.
Solution
When this error has occurred, lower the
intermediate presser. Then, reset the
error.

1. Check whether the voltage of the
thread trimmer shaft drive is lower
than 180V, and see if there are high
power devices around the device that
start and stop frequently; a voltage
stabilizer is provided as appropriate.
2. Replace the power board
