Machine will not feed material thru. Needle goes up and down but I cant pull material thru to catch the stitch

Check to make sure the feed dogs have not been dropped. Also, check that the stitch length is set at least to 2. If not that, then you machine probably needs service.

under the foot around the needle, there should be two rows of what look like teeth, these pull the material through and there will be an adjustment mechanism on the machine. Try leaving the foot up while you run the machine, you should see the teeth going up and down; if they are it is most likely just a case of setting up the amount of pull. I think it is adjusted with the wheel that sets the length of stitch.

Try setting the stitch length to a longer stitch. Increasing the stitch length should move the material faster. Also, make sure that the presser foot pressure is not to heavy. This shows up sometimes when you change fabric thicknesses (denim vs lightweight sheer) and the machine has difficulty moving the fabric. Try stitching on different fabric and see if it makes a difference. Also, if the material you are stitching is somewhat sticky, it will stick to the bottom of the presser foot (this is common when sewing vinyl, leather, etc.) If that is the case, you may want to check into getting a leather roller foot (it has wheels built into the presser foot that will turn as the fabric is pulled through by the feed dogs).

The needle may be bent, but surely the material should feed away from you not towards? Is the bobbin in correctly? If you have inadvertently left the feed dogs down the material will not be gripped and stay in the same place instead of moving. Check.

try using maximum stitch length, if still not working try removing needle plate and clean you teeth

I think you are saying no stitch is formed also referred to as the needle not catching thread. Below offers a variety of diagnoses and solutions which are straight forward.

Sewing Machine Needle Not Catching Thread

Below is general advice quoted from 6 common sewing machine problems solved:

Skipped stitches are usually due to a bad needle. The needle may have become damaged or bent by sewing material too thick for the needle, forcing material through the feed dog, or hitting a straight pin. If the problem seems to be consistently reoccurring, it may be due to forcing the fabric. Sewers should allow the feed dog to pull the fabric and only use their hands to guide the fabric through the feed. When sewing knitted fabrics, using a stretch needle can help prevent skipped stitches.

Sewing Machine Anatomy How Stitch is Made

try using a larger needle if your needle isn't large enough for the material you are using the needle may go thru but the thread wont go thru far enough to catch. The needle may be the correct size but just not sharp enough, the thicker the fabric the faster your needle will dull and a dull neele never works correctly

The presser foot is not suppose to feed. It's purpose is to hold the fabric in place as the feed dogs feed the fabric from the front to the back of the machine as stitches are formed.

Check the needle to be sure it is installed with the flat side of the needle shank facing the back of the sewing machine.

Refer to your manual to be sure the bobbin thread is feeding from the bobbin spool in the correct direction and through the guides.

Pull the bobbin thread up by lowering the threaded needed down and then back up. Pull both threads under the presser foot and to the back of the machine.

Set the stitch length to 2.

Place a scrap of fabric under the presser foot. Holding onto the ends of both threads, lower the needle into the fabric for the first stitch.

If the machine still does not stitch, the machine may need to go in for maintenance as the timing may need to be adjusted.

If the feed dogs are not moving, this also needs to be repaired by sewing machine service tech.

Are the feed dogs engaged? Janomes usually have a feed dog sliding switch, either on the back of the sewing machine at the bottom, or behind the accessory case. Be sure the check it out. Hope this helps!
