Question about Janome Jem Silver 662 Mechanical Sewing Machine

1 Answer

Needle not centered

I have been using my Janome Jem for a couple of years now-and just noticed the reason my seams are smaller than everyone elses. My needle is not centered.
How would I make an adjustment to the machine so the needle would be centered? I just checked my straight and zig zag stitches and they are off because of this, making it impossible to do some functions.
Thanks for any and all help,

Turn off and unplug machine FIRST !!
Have a lamp you can move to see what you are doing.

The faceplate is the cover that conceals the needlebar, lamp etc.
There should be a screw at the rear of the machine that secures it, and at the top join, a plastic clip to locate the two sides, be careful when separating, as these clips are prone to breaking with rough handling.

This is a Gem Gold diagram, but will be similar careful to keep the needle eye square to front if it starts to swivel on it's own axis.

Turn the handwheel manually to check current width of zigzag to assess how much you will need to move needlebar, (it will not be very far, probably 1mm max)

Loosen (anticlockwise) screw and then tighten just enough for there to be a little resistance, but enough so that you can still move the needlearm.

Gently turn the handwheel back and forth to assess the position of the needle, make small adjustments until you are happy and centred (in all possible ways !) then gently retighten the screw and reassemble.

While you have the faceplate off, just check for threads caught up around the moving parts, unwind them, not pull or cut, and take the opportunity to clean up lint etc from upper end of the needlearm and etc that is normally hidden.

Be gentle it twice, do it once !

If this image is too small via this method, then use the contact us form on our website and I shall send direct.

Best wishes

Janome Jem Silver 662 will only sew backwards. How do I adjust it so it will feed fabric correctly?

1) Check the feed dog pressure adjustment. 2) Check the feeding mechanism at the bottom. It may be too low to feed your cloth.

The hand wheel is not moving the needle at all

Check the hand wheel. There should be a smaller wheeel in the center of the hand wheel. Make sure it is locked in(turn center wheel clockwise or could be counter clockwise til snug)

I need a manual for this machine

I'mot sure if this will help.
I couldn't find manuals for Jem Silver machines on the Janome website, only Jem Gold or Platinum.
This is the partial manual for the Jem Gold 2, it should be enough to help with the basics of your machine, like threading etc.
Hope this helps!

Skipping stitches and knotting up underneath.

Here are a few things to try.

* Raise your feed dogs if your machine has this feature.

* When you start to sew a seam, hold the upper and bobbin thread tails. Hold them back and out of the way as you sew your first couple of stitches. This will keep them from getting caught in your machine.

* Your fabric may require a different needle. Generally, heavier fabrics require larger needles and thinner fabrics, smaller needles. You may also need a larger needle if you’re sewing through many layers of fabric. And make sure to use a ballpoint needle for knit fabrics and a sharp needle for woven (or a universal needle for either). And make sure your needle is appropriate for the type of thread you’re using.

* Adjust the pressure of your pressure foot, it may be too light for your fabric.

* If your upper thread and bobbin threads are different types, try using the same thread for both. And use a good quality, brand name thread.

* Change your needle plate. Try switching to a needle plate with a smaller hole (a straight stitch needle plate).

Important Note: If you change your needle plate, check to make sure your needle aligns perfectly with this smaller hole before starting to sew. A misaligned needle could hit the plate and break, which could be dangerous. And make sure to change your needle plate back for zigzag and other wide stitches.

Hope this helps.

Download a Janome (Jem 639) sewing machine manual

Just today  i got out my little janome i bought years ago and it is this model.  There was no "manual" with the machine.  All that came with it is a large 20X14 two sided print out.  I can scan and send this to you with an email address.
