Tajima TMBR-SC Series: Skipped Stitches and Solutions
Tajima TMBR-SC Series: Skipped Stitches and Solutions
The Tajima Single-Head Embroidery Machine TMBR-SC Series, equipped with a digitally controlled presser foot, is designed for high-quality embroidery across various fabric types. However, one common issue that many operators face is skipped stitches. Skipped stitches not only affect the visual appeal of the embroidery but can also cause frustration during production. Understanding the causes and solutions for skipped stitches can help keep your projects running smoothly.
Common Causes of Skipped Stitches in the TMBR-SC Series
1. Incorrect Needle Size or Type
Using the wrong needle for your fabric or thread is a leading cause of skipped stitches. The needle must be appropriate for both the thread and the material to ensure consistent stitching.
Solution:
- Choose a needle size that matches the type of fabric and thread being used. Thicker fabrics require larger needles (e.g., 90/14 or 100/16), while thinner fabrics work best with smaller needles (e.g., 75/11).
- Use embroidery-specific needles that have a larger eye to accommodate embroidery threads, reducing the chances of skipped stitches.
2. Worn or Damaged Needle
Needles can become dull, bent, or damaged over time, which reduces their ability to properly catch the thread and form stitches, leading to skipped areas in your design.
Solution:
- Replace the needle regularly, especially after completing a large project or after every 8-10 hours of use. A fresh, sharp needle will help eliminate skipped stitches.
- Inspect needles for any signs of damage or wear, and replace them immediately if they are bent or dull.
3. Incorrect Presser Foot Height
The digitally controlled presser foot on the TMBR-SC Series must be properly adjusted to apply the right amount of pressure on the fabric. If it’s set too high or too low, the fabric can shift or stretch, causing the needle to miss stitches.
Solution:
- Adjust the presser foot height according to the thickness of the fabric. For thick fabrics, increase the height slightly, while for thin fabrics, reduce the height to maintain consistent pressure.
- Ensure that the presser foot is evenly pressing down on the fabric without causing excessive movement or puckering.

4. Thread Tension Issues
Improper thread tension is a major contributor to skipped stitches. If the upper or bobbin thread tension is too loose or too tight, the needle may fail to catch the bobbin thread, leading to gaps in the stitching.
Solution:
- Balance the upper and bobbin thread tension. For delicate fabrics, reduce the tension, and for heavier materials, tighten the tension slightly.
- Test your tension settings on a scrap piece of fabric before starting your project to ensure the stitches are consistent and even.
5. Improper Threading
Incorrect threading can cause the machine to skip stitches, as the thread may not pass through the guides or tension disks properly, leading to inconsistent thread flow.
Solution:
- Double-check that the machine is threaded correctly, following the thread path from the spool through all tension guides and disks.
- Re-thread the machine if necessary, paying special attention to ensure the thread passes through the tension disks smoothly.
6. Fabric Not Properly Hooped
If the fabric is not hooped tightly, it may shift during stitching, causing the needle to miss its mark and resulting in skipped stitches.
Solution:
- Make sure the fabric is tightly hooped, with no slack or wrinkles. For thicker fabrics, ensure that they are hooped securely without excessive pulling.
- Check that the fabric is properly aligned in the hoop, and test the tension by lightly tapping the hooped area. The fabric should feel taut but not overly stretched.
7. Needle Deflection
Needle deflection occurs when the needle bends or is forced off-course during stitching. This can be caused by thick fabrics, multiple layers, or poor needle quality, and leads to skipped stitches.
Solution:
- Use a stronger needle for thicker fabrics or designs that involve multiple layers. For example, a heavier gauge needle (such as 90/14 or 100/16) can reduce deflection.
- Slow down the machine speed when working with challenging materials to give the needle more control and reduce the chances of deflection.
8. Bobbin Case or Bobbin Issues
Skipped stitches may also be due to issues with the bobbin or bobbin case. A poorly wound bobbin or incorrect placement can cause the thread to catch improperly, resulting in gaps in the stitching.
Solution:
- Make sure the bobbin is wound correctly and evenly. A poorly wound bobbin can lead to uneven tension, causing skipped stitches.
- Check that the bobbin is properly seated in the bobbin case and that the case is correctly installed in the machine. Clean the bobbin area regularly to remove lint and dust that may interfere with smooth operation.
9. Incompatible Needle and Thread Combination
An often overlooked cause of skipped stitches is the mismatch between the type of needle and thread being used. Different threads, such as metallic or thicker threads, require specific needle types to work smoothly.
Solution:
- Always match the needle size and type to the specific thread being used. For instance, metallic threads work best with needles that have larger eyes and smoother surfaces to prevent excessive friction.
- Use embroidery-specific needles that are designed for the type of thread you are using, especially when working with specialty threads like polyester, rayon, or metallic.
10. Incorrect Stabilizer
Using the wrong type of stabilizer can lead to fabric movement during stitching, which may cause the needle to miss stitches, especially with stretch fabrics or lightweight materials.
Solution:
- Select the appropriate stabilizer for the fabric you’re working with. For stretchy fabrics, use a cut-away stabilizer for better support, while tear-away stabilizers are more suitable for non-stretchy, lightweight fabrics.
- Use an additional layer of stabilizer for more complex designs or when working with heavy embroidery.
11. Bobbin Tension Problems
Improper bobbin tension can directly affect stitch quality. If the tension is too loose or too tight, the machine may fail to form proper stitches, resulting in skipped areas in your design.
Solution:
- Adjust the bobbin tension according to your fabric and thread type. It’s essential that the bobbin tension complements the upper thread tension for consistent stitches.
- Regularly clean the bobbin area and the bobbin case to remove any lint or thread debris that could affect tension.
12. Machine Speed Too High
Operating the embroidery machine at high speeds can lead to skipped stitches, especially when working with delicate fabrics, intricate designs, or thicker threads.
Solution:
- Lower the machine speed, particularly when embroidering detailed designs or working on more challenging materials like thick fabrics or specialty threads. A slower speed gives the machine better control and reduces the risk of skipped stitches.
- Experiment with different speed settings and find the optimal speed for each type of project.
13. Thread Quality
Low-quality threads can lead to inconsistencies in tension and friction, causing the machine to skip stitches or fail to catch the thread properly during stitching.
Solution:
- Always use high-quality embroidery threads from reputable brands. Inferior threads are prone to breakage, tangling, or uneven tension, which can result in skipped stitches.
- Test your thread before starting a large project to ensure it runs smoothly through the machine and doesn’t cause tension issues.
14. Thread Path Obstructions
Obstructions in the thread path, such as small knots or tangles, can interrupt the smooth flow of the thread and cause the machine to skip stitches. These obstructions can be caused by dust buildup or incorrectly placed thread spools.
Solution:
- Inspect the thread path for any tangles, knots, or dust, and ensure the thread is properly flowing through all guides and tension disks.
- Clean the thread path regularly and make sure there is no lint or thread buildup around the guides and tension points.
15. Fabric Tension in the Hoop
Fabric that is too tight or too loose in the embroidery hoop can cause skipped stitches. If the fabric is stretched too much, it can distort during stitching, causing the needle to miss stitches.
Solution:
- Ensure the fabric is hooped correctly with just enough tension to hold it in place. The fabric should be taut but not stretched out of shape.
- Test the tension by lightly tapping the hooped fabric — it should feel firm, like a drum, without excessive pulling.
16. Presser Foot Pressure Too Low or High
Even with a digitally controlled presser foot, incorrect pressure settings can cause skipped stitches. If the presser foot is applying too much or too little pressure on the fabric, it can cause the fabric to shift or not sit evenly, leading to missed stitches.
Solution:
- Adjust the presser foot pressure based on the thickness of the fabric. Heavier fabrics require more pressure, while lighter fabrics need less to avoid puckering or shifting.
- Use the digital presser foot settings on the TMBR-SC to fine-tune the pressure and test it on scrap fabric before starting the main project.
17. Needle Bar Misalignment
Needle bar misalignment can cause the needle to miss its intended point of entry into the fabric, leading to skipped stitches. This can happen due to mechanical wear over time or accidental knocks to the machine.
Solution:
- If you suspect the needle bar is misaligned, have a technician check and realign it. Regular maintenance and servicing can prevent issues like this from occurring.
- Avoid moving or bumping the machine too roughly, as this can cause alignment issues.
Conclusion
Skipped stitches can be a frustrating issue on the Tajima TMBR-SC Series, but with careful attention to needle selection, fabric preparation, and machine settings, you can minimize the problem. Regular maintenance, proper threading, and correct tension adjustments are key to preventing skipped stitches and ensuring smooth embroidery. By following these tips, you’ll be able to produce high-quality embroidery designs with fewer interruptions and errors.
