Diagnostics Tests
Motor Sensor Test
The “Motor” Sensor test can help you determine whether
there may be a problem with the Janome Quilt Maker
Pro 18 motor. Slowly rotating the handwheel should
result in a pulsing audible “beep.” If you get a constant
solid “beep” or no “beep” at all, this indicates a failed
test and the machine should be inspected by a qualified
Janome repair technician. (Figure 45)
Press the “Main” button to return to the “Regulated” or
“Manual” menu screen or the “Back” button to return to
the “More” menu screen.
Needle Sensor Test
The Needle Sensor test will indicate whether the needle
position sensor is functioning properly. Rotating the
handwheel should result in a “beep” for half of a stitch
cycle followed by no “beep” for the other half. (Figure 46)
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 qualified
Janome 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 functionality 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 47)
Press the “Main” button to return to the “Regulated” or
“Manual” menu screen or the “Back” button to return to
the “More” menu screen.
