How to fix a Janome 1600P when the needle thread is not cut?
- B
  Brian FernandezAug 1, 2025
  If the needle thread is not being cut, it could be because the static cutter is dull, in which case you should replace or grind the static cutter blade. Another possibility is that the static cutter blade is out of position, requiring adjustment. It may also be caused by skipped stitches before thread cutting, so reset the needle at the proper angle, reduce the check spring stroke, and adjust the needle to hook timing.

What to do if my Janome Sewing Machine skips stitches at the beginning of the seam due to a too short tail of the thread after thread cutting?

  If you're experiencing skipped stitches at the beginning of the seam because the thread tail is too short after cutting, it could be due to several factors. The auto tension release might not be sufficient, so adjust it. The needle to cutter cam timing might be too early, requiring adjustment. The thread drawing lever could be out of position, so adjust its position. Also, the static cutter blade might be out of position, so adjust that as well.

Why is the bobbin thread not cut on my Janome Sewing Machine?

  Amanda KerrAug 11, 2025
  If the bobbin thread isn't being cut, it could be due to the thread cutter blade being out of position; in this case, adjust the stroke of the thread cutter blade. Another cause could be the thread guide plate being out of position, so adjust its position. Finally, ensure that you are using the proper hook.

Why does the tail of the needle thread appear on the right side of the fabric with my Janome Sewing Machine?
- B

  If the tail of the needle thread appears on the right side of the fabric, it could be due to a few reasons. The pretension might be too loose, in which case you should tighten it. Alternatively, the needle to cutter cam timing may be too late, requiring adjustment. Finally, the static cutter blade might be out of position and need adjustment.

What to do if the needle thread bunches up on the wrong side of the fabric at the beginning of the seam with my Janome 1600P Sewing Machine?

  Daniel JohnsonAug 21, 2025
  If the needle thread bunches up on the wrong side of the fabric when starting a seam, it's possible that too long a tail of the needle thread is left after thread cutting. To resolve this, you may need to adjust the needle to cutter cam timing, or adjust the position of the static cutter blade.

  If the thread slips out of the needle eye when you start sewing, it could be because the needle to cutter cam timing is too late, so you should adjust it. Another possibility is that the thread drawing lever is out of position, requiring you to adjust its position.
