Avanté User Manual
If you hear a constant beep or no beep at all for a full
360° rotation of the handwheel, this indicates a failed
test and the machine should be inspected by a quali-
fi ed Handi Quilter repair technician.
Press the “Main” button to return to the “Regulated”
or “Manual” menu screen or the “Back” button to
return to the “More” menu screen.
X Motion Sensor Test
Use the X Motion Sensor test to verify functional-
ity of the “X” stitch regulator encoder (the encoder
mounted at the rear of the carriage). As you slowly
move the carriage left and right you should hear a
pulsing “beep” that pulses faster as you move faster.
A solid beep, no beep, or periods of irregular beeping
(with constant motion) indicate a problem with the
“X” encoder. The most likely cause of a problem is a
stitch regulator wheel that is not making consistent
contact with the track. Check the spring tension on
the sensor assembly on the carriage to assure that
it will easily return to the fully extended position
after being compressed. Also assure that the track
is straight with no dips or indentations and that it is
clean and free of contamination. Other causes are
an unplugged or damaged cable or possibly an issue
with the main control board. (Figure 41)
Press the “Main” button to return to the “Regulated”
or “Manual” menu screen or the “Back” button to

Motor Speed Sensor Test
The “Speed” Sensor test can help you determine
whether or not there is a problem with the HQ
18
Avanté speed sensor. Before performing this test,
remove the bobbin case and the top thread. Press
the “Start” button and the machine will begin slowly
rotating. The white box will show a number that
should stabilize at 100 if the sensor is functioning
properly. Pressing “Start” again will stop the ma-
chine. (Figure 42)
Press the “Main” button to return to the “Regulated”
or “Manual” menu screen or the “Back” button to
return to the “More” menu screen.
