Motor Speed Sensor Test
The “Speed” Sensor test can help you determine whether
or not there is a problem with the Janome Quilt Maker Pro
18 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
machine. (Figure 48)
Press the “Main” button to return to the “Regulated” or
“Manual” menu screen or the “Back” button to return to the
“More” menu screen.
Y Motion Sensor Test
Use the Y Motion Sensor test to verify functionality of the
“Y” stitch regulator encoder (the encoder mounted to the
rear power pod side machine wheel). As you slowly move
the carriage toward and away from you, 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 “Y” 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
machine to assure that it will easily return to the fully
extended (down) 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 49)
Press the “Main” button to return to the “Regulated” or
“Manual” menu screen or the “Back” button to return to the
“More” menu screen.
Keypad Test
The Keypad test allows the user to press any of the
four keys on the front or back handles to verify that the
Janome
18
Quilt Maker Pro 18 is reading the buttons as they
are pressed. When a key is pressed the name of the key
that is pressed will appear in the white box. When it is
released, the name will disappear. Perform this test on the
rear display for the rear keys, and the front display for the
front keys. (Figure 50)
Press the “Main” button to return to the “Regulated” or
“Manual” menu screen or the “Back” button to return to the
“More” menu screen.
