Hello Ms. Cindy,
As for your presser foot,...
What you need to know about your presser foot is it's official intended
purpose.
Which is to simply keep the fabric from rising up off the needle plate, if
and only if, the fabric has a tendency to hang on to the needle as the
needle moves up during it's upward stroke. ...Such as when sewing into
dense fabric or fabric with dense embroidered stitches.
I've always said they should change the name to something more like
"fabric
hold down stick" as opposed to "presser foot". Very often people mistakenly
call it the "pressure foot".
There is no official procedure for centering the presser foot that I'm
aware of. If you were to attempt to center it, you could use your good ole
trusty eye balls. It's okay if the presser foot is not perfectly centered
with the needle in front of it. (This is assuming that your needle is
centered with the rotary hook and needle plate like it aught to be.) Now if
your presser foot is on something like a 45 degree angle, you've got a
problem.
What's more important than centering is the spacing between the front of
the presser foot and the back of the needle. If in the process of being
bent from something other than the factory set position, the presser foot
was pushed forward, then you may experience a clicking between the presser
foot and your needles when you color change. If it's bad enough, you could
possibly break needles. I've only seen this twice in my years of servicing
machines.
Now, if you just can't sleep at night due to your presser foot not being
just right, you can try this procedure with patience and a small pair of
sturdy needle nose pliers.
DISCLAIMER*** IF YOU DAMAGE YOUR MACHINE IN THE PROCESS, YOU MAY POSSIBLY
VOID YOUR WARRANTY- IF ANY ARE IN EFFECT.
I suggest you read through these instructions first from start to finish
before attempting.
1) Color change to needle number 1
2) Click on "Maintenance"
3) Click on "Head Timing"
4) Click on "Bottom Center"
-Now the "active needle" and presser foot should be in the "down" position.
-Remove your Right Side Black Plastic Cover. (5 screws)
-This will require a 3mm and a 2.5mm Allen wrench (usually black in color
and shaped like the letter "L")
-With the screws out, I like to rotate the plastic cover 90 degrees counter
clockwise as I remove it from the face of the machine. (To reinstall it
simply rotate the cover in the opposite direction as you position it back
onto the machine.)
-You should now see the anatomy of the presser foot assembly.
-Identify (see) where the presser foot arm is tack welded to the bottom
ringlet that slides up and down on the "presser foot shaft".
-Support (grab) the presser foot just below this welded point with your
needle nose pliers so that you do not put any unnecessary strain on this
joint when bending the presser foot back to it's original position.
-While holding the pliers in your right hand and the bottom end of the
presser foot with your left hand, "encourage" (gently push, pull, bend,...)
the presser foot to the position where it's as vertical as possible when
viewed from the left or right sides of the machine, and relatively centered
with the needle when viewed from the front of the machine.
-*** NOTE!!! IF YOU MAN HANDLE THIS GENTLE PRESSER FOOT TOO MUCH OR BEND IT
TOO FAR, TOO MANY TIMES, YOU RUN THE RISK OF BREAKING THE DARN THING OFF AND
THIS WILL REQUIRE THE SERVICES OF A TECHNICIAN TO REPLACE IT WITH A NEW ONE.
(Unless you're willing to tackle it yourself.) It's only made out of thin
aluminum!
-NOW PUT YOUR BLACK PLASTIC COVER BACK ON THE FACE OF THE MACHINE BEFORE YOU
EVEN THINK ABOUT COLOR CHANGING TO ANY OTHER NEEDLES!
-Now click on "Head Up" on the PC.
-Close the Maintenance window.
-Double check your work.
Hope this helps you out.
Call if you run into any problems.
Good Luck
Your friendly neighborhood Melco Maintenance Man,
That's "E3M" for short.

Can anyone tell me what the procedure for centering the pressure foot
called? I have one machine that is not sewing well and when I look at it,
the needles are not centered with the pressure foot. The needles do look to
be calibrated with the rotary hook and needle plate but not the pressure
foot. Thanks
