Voyager: Manually Extending and retracting the Catcher (for testing purposes)
1.  Power the machine on.
2.  Lower the presser foot using the P.FOOT button.
3.  Find the gap, shown below, under the fixed head, and with a screwdriver, extend the catcher as shown in the animation to check that it extends cleanly between the thread holder.  You can perform this same step 3 in reverse if the catcher fails to return to its full-closed position.
