I need to replace the metal bar that snaps onto the presser foot.

The Janome Memory Craft 3000 uses a low shank snap-on presser foot with a presser foot holder for most of its standard presser feet. See page 17 (page 19 of the PDF) of the User Manual available from Janome on the retired machine support page: https://www.janome.com/support/retired-machine-manuals/ . The current link to the manual is https://www.janome.com/siteassets/support/manuals/retired/computer/inst-book-mc3000.pdf . For specific presser feet that originally came with the machine, see page 3 of the manual (page 5 of the PDF). You can get presser feet that are known to be compatible at most sewing machine supply vendors, including https://www.sewingpartsonline.com/janome-memory-craft-3000-sewing-machine-parts.aspx?filter.ptype_gmcfeed_1=%20Presser%20Feet&index=39 or https://www.sewingmachinesplus.com/janome-mc3000-parts-accessories.php . A few presser feet have their own shank and require you to take off the holder.

I hope this helps.

Please add a comment with the specific model of Janome Schoolmate sewing machine.

Fpr the Janome Schoolmate S-3015, make sure that the needle is fully up and raise the presser foot. Then press the red button on the back of the presser foot holder to have that foot drop off. Set the pressure dial to 3 before attaching the new presser foot. For snap-on feet, align the pin of the presser foot (the horizontal bar in the middle of the foot) under the presser foot holder. Lower the presser foot holder (using the presser foot height lever) until it locks onto the foot.

For the zipper foot, you need to fit the rear pin on the foot into groove at the back of the presser foot holder. Then lower the presser foot holder onto the zipper foot.

These are shown on page 11 (14 of the PDF) of the manual. You can download the manual here: http://janome.com/en/machines/sewing/schoolmate-s-3015/ . The direct link to the manual is http://janome.com/siteassets/support/manuals/school-models/schoolmate3015.pdf .

For the S-7330, you need to again raise the needle and the presser foot. Press the lever towards (it moves slightly up, not down) the presser foot holder. Then line up the pin on the foot under the presser foot holder and lower the presser foot holder onto the foot so that it locks. This is also in that sewing machine's manual, here: http://janome.com/siteassets/support/manuals/school-models/inst-book-s-7330esf.pdf . See page 14 (18 of the PDF).

I hope this helps.

Unfortunately you are probably not going to be able to fix this.
It needs a sensor adjusted (probably), or a component replaced.

try www.sewingpartsonline.com for replacement parts

http://www.sewingpartsonline.com/presser-foot-shank-elna-janome-kenmore-804509000.aspx looks like it is the one you need I think.

there are 2 type of presser bar foot clamps
one allows you to snap on the foot--raise & then lower the presser foot holder until the cut out is directly above the pin on the foot,,as you lower the presser foot holder the presser foot will automatically engage when put down on the pin area

the second is a shank & foot combined & there is a screw on the presser bar,,unscrew it some & put the shank up around the screw & retighten the screw

i too have the same problem from yesterday .. plzzzz helppp

If you haven't already solved this problem, they are easy to get from a janome dealer

This machine needs to visit an authorized Janome technician.

Not shure you can embroider on an MC4000, i think this is only a sewingmachine.

But to change presser fot:

If it a "snap on" foot, when foot lifted, press the "button" on the back of the needle bar (on the bottom) this would release the presser foot.

If is a large foot, you have to unscrew the screw on the left side of the needlebar, and change the whole foot.
