Janome 3160QDC user manual

QDC in Janome 3160QDC stands for Quilter's Decorative Computer. This implies that the machine is computerized and is designed not only for quilting but also for decorative sewing.

The Janome 3160QDC sewing machine weighs approximately 12 pounds (5.4 kg).

The specific settings for your Janome 3160QDC sewing machine may vary depending on the type of fabric and stitch you are using. However, here are some general recommendations:
1. Stitch type: Select the desired stitch pattern on the machine's stitch menu. This can be done by turning the stitch selector dial or using the digital display if your machine has one.
2. Stitch length and width: Adjust the stitch length and width according to your project requirements. Smaller stitch length for finer fabrics and larger stitch length for stronger seams. Stitch width can be adjusted for decorative stitches.
3. Tension: Adjust the tension dial to control the tightness of the stitches. The ideal tension setting may vary depending on the fabric you're using. Test sew on a scrap piece of fabric to ensure the stitches are balanced and not too loose or too tight.
4. Presser foot pressure: Some machines have a presser foot pressure adjustment feature that controls how firmly the presser foot holds the fabric. Adjust it based on the thickness of your fabric. For lightweight fabrics, reduce the pressure, and for thicker fabrics, increase it.
5. Needle position: Use the machine's needle position selector to set the needle in the desired left, center, or right position.
Remember to refer to your sewing machine's manual for detailed instructions on adjusting specific settings for your model. Additionally, experimentation and practice will help you determine the best settings for different sewing projects.

There could be several reasons why your Janome sewing machine is not sewing properly. Here are a few common issues and their potential solutions:
1. Improper threading: Make sure the machine is threaded correctly, following the instructions provided in the user manual. Check that the thread is properly inserted in the tension discs and guides, and ensure that the bobbin is inserted correctly.
2. Tension problems: Improper tension settings can lead to issues like loose, tight, or skipped stitches. Consult the manual to adjust the upper and bobbin tension to the recommended settings for the type of fabric you are working with.
3. Bent, dull, or incorrect needle: A damaged or wrong needle can cause issues with stitching. Make sure you are using the correct needle size and type for your fabric. Replace the needle if it is bent or dull.
4. Incorrect stitch selection: Verify that you have selected the appropriate stitch for the desired sewing technique. Some stitches may not work well with certain fabrics or purposes.
5. Dirty machine or jammed bobbin: A dirty machine can cause problems with the sewing process. Clean the machine, removing any lint or debris, and make sure the bobbin area is clear of any thread jams.
6. Machine maintenance: Regular maintenance is crucial to keep your sewing machine in good working condition. Check if any parts need lubrication or if there are any broken or worn-out components that require replacement.
If you have checked and attempted these solutions without success, it may be beneficial to consult a professional sewing machine technician or contact Janome's customer support for further assistance.
