User Manual
• Press the Needle Sensor Test bu琀琀 on. Rotate the hand wheel. While rota琀椀 ng, you should hear a
beep for half of a s琀椀 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° rota琀椀 on of the handwheel, the test has failed and the machine should
be inspected by a qualifi ed Janome repair technician.
T 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 bu琀琀 on. Then press the Start bu琀琀 on on the handlebars and the
machine will begin slowly rota琀椀 ng. The display will show a number that should stabilize at 100 if the
sensor is func琀椀 oning properly. Press Start again to stop the machine and the test.
To perform the Keypad Test
The Keypad test verifi es that the Quilt Maker Pro 16 is reading the handlebar bu琀琀 ons when they are
pressed.
• Press the Keyboard Test bu琀琀 on. Then press one of the handlebar bu琀琀 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-Mo琀椀 on Sensor Test
Use the Y-Mo琀椀 on Sensor test to verify func琀椀 onality of the Y-axis s琀椀 tch regulator encoder (the encoder
mounted to the rear le昀琀 , machine wheel).
• Press the Y-Mo琀椀 on Sensor test bu琀琀 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 mo琀椀 on) indicate a problem with the Y-axis
encoder.
 NOTE: The most likely cause of a problem is a s琀椀 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) posi琀椀 on a昀琀 er being compressed. Also assure that the track is straight
with no dips or indenta琀椀 ons and that it is clean and free of contamina琀椀 on. Other causes are an unplugged or
damaged cable or possibly an issue with the main control board.
