Presser Feet for XR-7700

Are you using the correct presser foot for your machine? Presser feet shanks come in different lengths. There are also a couple of presser feet (like darning or free-motion-quilting feet) that are shorter than standard because they are made to be used with the feed dogs dropped and the fabric can be manually manipulated. If it's the correct foot, then the machine probably needs to be adjusted.

Would suggest taking your machine for service. Could be the feed dogs need adjustment or realignment. Also, make sure you are using the correct presser foot for your machine. With all the new machines that have 7mm and 9mm presser feet (most older machines have 4mm or 5mm), using the incorrect width presser foot may cause the fabric to skew.

There are most likely some numbers missing from the model number you provided. Usually, there is a 3-digit beginning number, ie 115, 385, 401...

I am unable to find model information based on your number, but you can most likely get a user's manual through Sears or try searching the internet (Make Model manual), ie:

Kenmore Sewing Machine Manuals Instruction and Repair Manuals

Sewing machines generally have two ways to disable feed dogs. One way is a lever or knob on the machine itself that physically "drops" the feed dogs so they are below the needleplate. The feed dogs will continue to operate but since they are below the sewing surface, they will not have an effect on the fabric movement. The other way is an accessory that attaches to the needleplate which covers the feed dogs and creates a flat sewing surface.

Another item that is important for free motion quilting is a darning foot or free motion foot. These presser feet are physically shorter in height than a standard presser foot. This means the darning foot, when lowered, does not apply "pressure" to the fabric when it is lowered. It, instead, provides leeway between the presser foot and the fabric so there is room to manually maneuver the fabric while stitching.

You'll just need to CONFIRM that the presser foot shank is correct for your machine (low shank, high shank, slant shank).

There are probably a multitude of designs available for your machine, either Kenmore or generic brands. Once you've determined your machine's shank, it would be a personal decision as to the design you'd prefer, which could be metal or plastic, closed, open, or clear see-thru as well as various shapes, round, oval, etc. There are also some feet that are spring-loaded so they "hop" while you stitch, or feet that are solid.

These are examples of different darning/free motion presser feet.

Your 440QE takes the new style Bernina feet (the ones with red writing on them.) Where it attaches to the presser foot bar, the front is flat and the back has a little square cut-out. Be sure you buy the narrow foot not the wider foot (& wider stitch) for the machines with a bigger foot print. (You'll be looking for 5mm wide, not the ones with the bigger foot print--7mm.) I do have a couple of 7mm feet for my 440QE and they do work but I read somewhere that they may be a little *hard *on* the 440, so I don't use them a lot. The 7mm presser foot is wider than the feed dogs on the 440QE.

Ugh, Fixya thinks I'm using bad language. Not!

If the width of both machines' presser feet are the same, the only thing you need to worry about is the shank and the form of attachment the shank has to the machine.

According to this, the feet may be compatible:
Generic Presser Feet Accessories
You'll need to verify that the shanks are the same between both machines. Perhaps the Juki dealer can tell you if the feet are compatible.

However, if the presser feet are not compatible with both machines, you can purchase an snap-on adapter shank for the Juki and pick up a kit of snap-on presser feet (these are generic, not Juki made) and you will be set to go for very little outlay of finances. In addition, you could pick up a snap-on adapter for the Husqvarna and you would be able to use the snap-on feet on both machines (in case you don't have some feet for your existing machine).

Has that particular presser foot worked in the past? Do the other presser feet work?

If it hasn't been used before, check that it is the correct foot for the machine. Is it perhaps a darning foot or free motion foot? If so, those particular feet are made to Not rest on the feed dogs so that the fabric can be manually moved without the use of the feed dogs.

If none of the presser feet work with the machine, then the needlebar has probably shifted. It may be best to take it for service as it may require specific tools and gauges to adjust it properly.

You need a special foot for free motion quilting--it is slightly shorter in height than a regular presser foot, which essentially provides space between the presser foot and the needle plate to manually move the fabric. Sometimes machines came with a standard darning foot accessory. Your Pfaff dealer probably has at least one style in stock. But there are other specialty feet you can probably use, ie Big Foot, clear free motion foot, C-shaped, oval, etc. You can also purchase a shank adapter (verify it is the correct shank for your machine) and use it with a kit of snap-on presser feet so you can have a variety of presser feet for different functions.

Your machine feed dog is ageing or need to be realigned or if you have a satin presser feet try to use this feet instead.

You probably do not have lever to put the feed dogs down. That's why you have a cover. To free style embroider or darn you don't need a foot but the presser foot has to be down and as you run the machine, YOU will be doing the stitching by moving your fabric back and forth. This is usually done with a wooden embroidery hoop so that your fabric stays taught. I have done it on jeans without a hoop. Hope this helps.

The switch for the FEED DOGS is on the left side of the machine.
