beep for half of a sti tch cycle followed by no beep for the other half. If you hear a constant beep or
no beep at all for a full 360° rotati on of the handwheel, the test has failed and the machine should
be inspected by a qualifi ed Janome repair technician.
To perform the Motor Speed Sensor Test To perform the Motor Speed Sensor Test
The Motor Speed Sensor test helps you determine whether or not there is a problem with the Quilt Maker
Pro 16 speed sensor.
 NOTE: Before performing this test, remove the bobbin case and the top thread.
• Press the Motor Speed Sensor butt on. Then press the Start butt on on the handlebars and the
machine will begin slowly rotati ng. The display will show a number that should stabilize at 100 if the
sensor is functi oning properly. Press Start again to stop the machine and the test.

pressed.
• Press the Keyboard Test butt on. Then press one of the handlebar butt ons. When you press the
key, the name of the key appears in a white box on the screen. When you release the key,
the name disappears.
To perform the Y-Moti on Sensor Test
Use the Y-Moti on Sensor test to verify functi onality of the Y-axis sti tch regulator encoder (the encoder
mounted to the rear left , machine wheel).
• Press the Y-Moti on Sensor test butt on. Slowly move the machine toward and away from you. You
should hear a pulsing beep that pulses faster as you move the machine faster. A solid beep, no
beep, or periods of irregular beeping (with constant moti on) indicate a problem with the Y-axis
encoder.
 NOTE: The most likely cause of a problem is a sti tch regulator wheel that is not making consistent contact
with the track. Check the spring tension on the sensor assembly on the machine to assure that it will easily
return to the fully extended (down) positi on aft er being compressed. Also assure that the track is straight
with no dips or indentati ons and that it is clean and free of contaminati on. Other causes are an unplugged or
damaged cable or possibly an issue with the main control board.
