Tajima TMEG Series: Common Problems & Fixes Guide
Quick answer: Most common issues on Tajima TMEG machines, such as thread breaks or poor stitch quality, are often resolved by checking thread path, tension, needle condition, or ensuring proper data transfer. Always start with basic checks before replacing parts.
The Tajima TMEG series embroidery machines are workhorses, known for their reliability. However, like all complex machinery, they can encounter issues. This guide provides common problems reported by operators, along with practical troubleshooting steps and information on the parts that often need attention. We focus on empowering you to diagnose and fix issues quickly, minimizing downtime.
Two-minute checks before you open anything
- Is the machine powered on and plugged in securely?
- Are all emergency stop buttons disengaged?
- Are all safety covers and doors closed properly?
- Is the thread path clear and free of tangles or breaks?
- Is the needle inserted correctly and not bent or dull?
- Is the bobbin wound correctly and inserted with proper tension?
- Is the fabric properly hooped and stabilized?
- Are there any visible obstructions around the needle, hook, or head movement area?
1. Frequent Thread Breakage high likelihood
How to tell
The machine stops unexpectedly, an alarm sounds, and the upper thread is visibly broken. This can happen repeatedly during a design.
Fix
- Check the thread path for any snags, burrs, or obstructions. Ensure thread guides are clean and smooth.
- Verify upper thread tension. It should be firm but not overly tight. Adjust the tension dial if necessary.
- Inspect the needle for bends, burrs, or dullness. Replace the needle if any damage is found.
- Ensure the bobbin is wound correctly and inserted with proper tension. Clean the bobbin case.
- Check the hook timing. If the hook is out of sync with the needle, it can cause thread breaks. Refer to your machine's manual for timing adjustment procedures.
- Examine the thread take-up spring for proper function and damage. Replace if broken or weak.
Consider replacing worn components like the Tajima 0C0220060060 Hook Thread Take-Up Spring, Tajima 0C0220080000 EF0910000000 Spring Hook, Tajima 516503010011 MX0521010000 Thread Guide Collar Ceramic Coil 1.8mm, or the Tajima 050320350000 Thread Block if they show signs of wear or damage.

2. Needle Breakage medium likelihood
How to tell
The machine stops abruptly, often with a loud 'snap' sound, and the needle is broken, bent, or missing its tip. This can damage the presser foot or needle plate.
Fix
- Replace the broken needle with the correct type and size for your fabric and thread.
- Check that the needle is inserted correctly, fully seated, and facing the right direction.
- Inspect the presser foot for damage or misalignment. Ensure it is not hitting the needle.
- Verify that the hoop is securely fastened and the fabric is properly hooped without excessive slack or puckering.
- Check the needle bar's lower dead point stopper and guide for wear or damage. Misalignment here can cause needle deflection.
- Ensure the machine's timing (needle depth and hook timing) is correct. Incorrect timing can cause the needle to strike the hook or other components.
If needle breaks are persistent, inspect the Tajima 090420060017 Stopper Lower Dead Point Needle Bar Connecting Stud and Tajima Needle Bar Guide 090450036011, 090450049011, 09045005Y011 for wear.

3. Poor Stitch Quality / Skipped Stitches medium likelihood
How to tell
Embroidery appears loose, uneven, or has gaps where stitches should be. Loops may appear on the top or bottom of the fabric.
Fix
- Adjust upper and bobbin thread tension. Top loops usually mean upper tension is too loose; bottom loops mean bobbin tension is too loose.
- Change the needle. A dull, bent, or incorrect needle can cause skipped stitches.
- Clean the bobbin case and rotary hook area. Lint and debris can interfere with stitch formation.
- Ensure the presser foot is set correctly for the fabric thickness. The Tajima EF0613220000 EF0613210000 090460040020 090460040031 Presser Foot Bushing Guide Collar should be in good condition.
- Check for proper hook timing. If the hook is not catching the needle thread loop at the correct moment, stitches will be skipped.
- Verify that the fabric is properly hooped and stabilized. Movement of the fabric during stitching can cause inconsistencies.
Worn Tajima 0C0220060060 Hook Thread Take-Up Spring or Tajima 0C0220080000 EF0910000000 Spring Hook can affect tension and stitch quality. Also, ensure the Tajima 516503010011 MX0521010000 Thread Guide Collar Ceramic Coil 1.8mm is smooth.
Parts involved: Needles & needle bars → Thread path & tension → Rotary hooks & bobbin cases → Presser feet & sewing parts → Hoops & frames →
4. Machine Not Reading Designs / Data Transfer Issues low likelihood
How to tell
The machine displays an error message related to file reading, cannot find the design, or fails to load data from the floppy drive or USB.
Fix
- Ensure the design file is in the correct format (e.g., .DST) and is not corrupted.
- If using a floppy disk, try a different disk or clean the floppy drive head. Floppy drives are prone to failure.
- If using a USB device, ensure it is formatted correctly (FAT32) and the file structure is recognized by the machine's reader.
- Try a different USB stick. Some older machines are particular about USB drive brands or sizes.
- Check the connection of any external USB linker or floppy emulator. Ensure cables are secure.
- If the machine has an internal floppy drive, consider upgrading to a Gotek USB Floppy Drive Emulator Reader 720K Low Density 34-Pin for Tajima TMEG Embroidery Machines for improved reliability.
