Zipper foot not coming into contact with the material

a zipper foot is 1/2 a full foot so if push comes to shove and a local sewing machine shop doesn't have a generic foot, simply get another full fut and hacksaw 1/2 off

When I think 'higher lift' and leather - I think 'less pressure on the material' Ergo, release pressure on the pressure foot. Usually atop the left side of any machine. Press down on outer ring, to release pressure. Test on extra material. Hope this helps.

go to a pfaff shop or any sewing machine repair shop and get a 1/2 foot for zippers

Um, not sure what presser foot you are using--there are several.

If it is the invisible zipper foot, there is a groove in the bottom of the presser foot that straddles one strip of zipper teeth which positions it close to the needle. Zipper foot #4 snaps to either side to enable the needle to be close to the zipper teeth. The Narrow Adjustable Zipper/Straight Stitch and the Non-Stick Zipper Feet are moveable left or right.

Just like the regular working foot, most zipper feet look the same regardless of machine. At least, the part of the foot that is actually in contact with the work: small, solid--no thread slot or needle well in the middle--and a small notch on each of the left and right sides.

The zipper foot is the one that is 1/2 there in relation to a sewing foot. It allows the needle to come down next to the zipper teeth

1. Step 1 To prepare the fabric for a centered zipper application, use the standard presser foot to baste the opening of the fabric shut using 5/8 inch seam allowance. Press the seam allowance open. Place the zipper teeth side down on the seam allowance and pin the zipper to the seam allowance only.
   
2. Step 2 Release the standard presser foot from your machine. There may be a button or lever behind the foot that you need to press. Put the standard foot in its holder or someplace where it won’t get lost.
   
3. Step 3 Decide which side of the machine you want to attach the zipper foot to. Zipper feet are asymmetrical, with one side that’s wider than the other. You’ll want to put the narrow side toward the zipper teeth, and the wider side away from the zipper teeth.
   
4. Step 4 Attach the zipper foot to the sewing machine. You may need to line up the bar on the zipper foot with the presser foot holder, then lower the presser foot by lowering the lever. Raise the presser foot and make sure the zipper foot is securely attached.
   
5. Step 5 Place the prepared fabric with the pinned zipper in the sewing machine. Lower the needle into the zipper tape and the seam allowance only, then lower the zipper foot. Stitch the zipper tape to the seam allowance. To sew the other side of the zipper to the seam allowance, remove the zipper foot from the sewing machine and install it on the other side of the presser foot holder.
   
6. Step 6 Topstitch the outside of the fabric to each side of the zipper tape, making sure that the zipper foot is on the appropriate side of the machine for each side. Remove the basting with a seam ripper.
   

That should be your foot I'm guessing?!? The machine should have come with several?!? Like, a zipper foot, button hole foot etc. Mine (Janome SX 2122) are stored in my machine, in the top section where you load the thread. , you can use one of the others. Mine also has a spare basic foot...have a look and see if it's there either in or with your machine or with some of the extra parts it should have come with (may run into troubles if it's second-hand though...as you may not even have all of the parts)...if you don't have a basic foot you can often just use one of the other feet (like a zipper foot or something), which may not quite hold the material down, depending on what you're sewing, at least until you get a chance to get another basic foot...which you can get from any store that sells material or sewing machines. Hope that helps :)
