Adjusting The Hopping Foot Adapter - Janome QMP16SU Manual

Adjusting the Hopping Foot Adapter

The Janome QMP16SU features the "KinetiQuilt" hopping mechanism, enabling the hopping foot to move
(hop) up and down, and dwell on the fabric when the needle is in the fabric.
This enables fabric to move through the machine similar to a sewing machine with feed dogs. The dwell
time provides a longer hesitation of the hopping foot on the fabric and completion of the stitch cycle. The
results are better tension, less needle breakage, and increased hook life.
The factory default for the bottom of the presser bar, without a hopping foot or mount adapter, should be
about 1.5 inches above the needle plate when the needle is in the lowest position.
Check
With the hopping foot mount adaptor screwed into the presser bar about 13 turns there will be about 6
-8 exposed threads below the foot mount adaptor jam nut. Check the number of exposed threads below
the jam to confirm that it is close to this number. If it is not close to 6-8 exposed threads, this will alert
you that someone has adjusted the adaptor in or out. This may cause too much or too little tension on
the internal presser bar spring and may cause clicking in the mechanism.
 IMPORTANT: If there is improper spring tension on the presser bar the result will be stitch
problems, including skipped stitches.
 IMPORTANT: Check and adjust this if necessary before resetting the presser bar height internally
on screw C.
Adjust if necessary
Tool: 8 mm open-end wrench
1. Attach the hopping foot to the foot mount
adaptor. This helps you align the foot to the
needle it the final step.
2. Loosen the jam nut with the 8mm open-end
wrench.
3. Screw the mount adaptor in or out until there
are about six exposed threads below the jam
nut when tightened.
4. While holding the foot firmly, tighten the jam
nut while making sure the hopping foot ring is
centered on the needle.
