Top 20 Janome 1600P-DB Mechanical Sewing Machine Questions & Answers

No errors coming up? Cleaned unit inside or Air cleaned unit, sometimes these units, if inside bobbin area or threading pattern, if there is dust, fluff or something they will cause unit to be intermittent. Try rethreading and blowing out unit

Take it in for service. It could be the spring has become depressed (when storing the machine, make sure the presser foot is always stored in the Down position), or something has become detached or loose. ...

Could be the machine is out of time. However, be sure that you are not pulling/pushing the fabric through the machine. The feed dogs should be pulling the fabric without assistance. (Is the weight of the fabric hanging over the edge of the table, pulling against the machine? The weight of the fabric should be resting on the table, and to make it easier, create a "puddle" with the fabric around the foot to reduce the amount of weight.) If the machine is having difficulty with the fabric, try using a walking foot. Also, check that the thread is not too large for the needle's eye. Could also possibly need a presser foot pressure adjustment to compensate for the thickness/weight.

Is the tension too tight? Are the tension discs clean? Remove bobbin case, clean it and re-thread as this may be jammed.

What does the left over piece look like?

Check that the thread is hooked into the little slit on the top side (pull down to hook in). It should trail across the centre of the bobbin. Check your needle as well. Lift the bobbin lid and turn the wheel to see what is going on down there. Also, make sure bobbin is not upside down. Side with little slit should be on top. Good luck

it is possible that the tension disk is going bad and needs to be replaced.

Try using a different brand of thread. I do quilting and have been using good quality thread and no problem.

Factory standard tension setting is the midway point between high & low number. However, machines vary.

These are some causes. The thread guide has been missed so re-thread the machine. Tension is too tight. Needle is blunt or bent. Thread is getting caught on the rough edge of the spool so turn spool around. Hope this helps

Normal top tension is 3-4; normal bobbin tension (iirc) is 35 grams. I'm betting, though, that a new needle, right way around and the correct size, would solve your skipping problems.

possible problems 1) too thick for the feed dog to move the fabric forward need; lighter tension 2) are the upper and lower threads the same kind of thread? 3) is the thread feeding properly from above? sometimes the spool can snag the thread causing the tension to jump and skip stitches

Ya, that's not good. Sounds like a set scew on the shaft has come loose (hopefully), other wise, could be looking at broken gears and that is more extensive. Take it to a service tech, or your Janome dealerSewing Tech

Check the needle to see if it is bent. If not then check the needle to hook timing. Turn the hand wheel until the needle is at it's lowest position. Start to bring the needle upward. As the needle gets to the edge of the hook/bobbin race the point of the hook should pass slightly above and behind the needle. If it isn't the timing is out. I would suggest bringing it to a trusted sewing machine repair person to reset the hook timing and check for any other damage.

I don't own a Juki but I know with my Bernette to always thread in the order shown on the diagram inside the front cover, usually upper looper, lower looper, then the right then left needles. Then raise the pressure foot and draw all four threads under it and out to the left rear of the sewing platform, lower the presser foot, press the foot pedal and hopefully, chain off.Also check that you are getting the thread into the tension dials correctly, pull downwards and there should be resistance on the thread, if this isn't there at all, then take thread out and try threading around the dial again to seat thread in fully.Sometimes, walking away, having a cup of tea, then coming back and starting fresh works. Clean and oil it, change needles, rethread from start to finish and hopefully it behaves.

Hi Leann: Think about how a sewing machine works. Now think about what kind of difference an 1/8th of an inch distance would make. Yes. You will need to adjust your top tension when you do free motion work. Keep in mind that plate is not just stopping your feed dogs from working... it's holding your materials that far away from the bed of the machine... so when the thread makes a loop and tightens for the stitch it has the extra 1/8th of an inch to make up for... if the tension isn't right... you got loops. There are no "specific" settings for tensions... you learn by doing you stitch a few stitches on like materials and tighten until you see a good stitch.

First ensure that it is not going to invalidate any warranty or guarantee by doing so ...and at the risk of repeating myself as per previous posts get in touch with http://www.janome.co.uk/index.php?option=com_chronocontact&Itemid=14

try adjusting the top thread tension for the loops try changing the needle and see if that help any if not then take the machine back and tell them what the machine is doingif the machine was adjusted, then they should have checked the stitches to make sure that the stitches were normal both forwardand backwards.

then it would be a good idea to have the machine servicedto find out if the lever is broken or stuck.
