remains after the thread is
trimmed, the needle may
become unthreaded when
embroidering begins again.
Set the remaining length of
thread to “Long Tail” on the
second page of the settings
screen.
p.227
The upper thread
does not reach
the bobbin thread
when
embroidering
begins.
There is no more thread in the
bobbin, the thread does not
feed from the bobbin, or the
thread that is fed from the
bobbin is too short.
Correctly thread the lower
thread.
p.38
Although the
thread is not
broken, a broken
thread error
occurs and the
machine stops.
If the thread breakage sensor in
the thread tension disc of the
thread tension knobs cannot
detect that the thread is being
fed, even if the machine is
running, a broken thread error
occurs and the machine is
stopped. If the thread came out
of the thread tension disc, even
though the thread is not broken,
the machine detects that the
thread is not being fed and stops.
Clean the tension unit.
Correctly pass the thread
through the thread tension disc.
If the broken thread error
occurs after the machine is
cleaned and rethreaded, the
sensor may be damaged.
Consult your nearest Brother
dealer.
