Tajima TMEZ Series: Common Problems & Fixes Guide
Quick answer: Common Tajima TMEZ problems include thread breakage (often due to tension, needle, or hook issues), skipped stitches (tension, needle, hook), needle breakage (timing, bent needle, hoop), and trimming failures (cutter assembly). Always start with basic checks like thread path, needle condition, and bobbin installation.
The Tajima TMEZ series is a robust line of embroidery machines, known for its precision and durability. However, like all industrial equipment, TMEZ machines can encounter common operational issues. This guide from 360 Digitizing Shop provides practical troubleshooting steps for the most frequently reported problems, helping operators quickly diagnose and resolve issues to minimize downtime. We focus on actionable fixes and identify the replacement parts you might need to get your machine running smoothly again.
Two-minute checks before you open anything
- Is the machine threaded correctly from spool to needle?
- Is the bobbin wound evenly and inserted correctly with proper tension?
- Is the needle new, sharp, inserted correctly, and the right type for your material?
- Is the fabric hooped tightly and correctly, without wrinkles?
- Are there any visible obstructions in the thread path, needle plate, or rotary hook area?
- Are all machine covers closed and safety interlocks engaged?
1. Frequent Thread Breakage high likelihood
How to tell
The machine stops frequently with a 'thread break' error, or you observe the thread snapping during sewing. This can happen on specific needles or across all heads.
Fix
- Check the entire thread path for any snags, burrs, or obstructions from the cone to the needle. Ensure thread guides are clear and not bent.
- Inspect the needle for burrs, bends, or dullness. Replace if any damage is found.
- Verify upper thread tension. It should be firm but allow the thread to pull smoothly. Adjust tension discs if too tight or too loose.
- Check bobbin tension and ensure the bobbin is wound evenly and inserted correctly into the bobbin case.
- Inspect the rotary hook for burrs or damage, especially around the hook point and thread finger. Clean any lint buildup.
- Ensure the thread is correctly seated in the thread take-up lever and tension release mechanism.
Consider replacing your KHS20-R Jumbo Rotary Hook for TAJIMA TME-DC, TMFX, TMB, TMAR, TMEZ & BROTHER BAS-415, BAS-416, BAS-423 Embroidery Machines if damaged. Ensure you have fresh, sharp needles.

2. Skipped Stitches or Poor Stitch Quality high likelihood
How to tell
Embroidery appears uneven, loose, or has gaps where stitches should be. Loops may appear on the top or bottom of the fabric. The machine might make an unusual 'thud' sound when skipping.
Fix
- Replace the needle with a new, correct size and type for your fabric and thread. Ensure it's inserted correctly and fully seated.
- Check upper and bobbin thread tension. Adjust as needed to achieve balanced stitches.
- Inspect the rotary hook for damage or lint accumulation. Clean thoroughly.
- Verify that the presser foot is set to the correct height and is not interfering with the needle or fabric movement.
- Check the timing between the needle and the rotary hook. If significantly off, this may require a technician, but minor adjustments can sometimes be made by experienced operators.
- Ensure the fabric is hooped correctly and taut, without wrinkles or slack.

3. Needle Breakage medium likelihood
How to tell
Needles snap frequently, often with a loud 'crack'. This can occur during stitching, trimming, or color changes.
Fix
- Replace the needle with a new, correct size and type. Ensure it is inserted correctly, fully seated, and facing the right direction.
- Check for any obstructions in the needle plate or presser foot that the needle might be hitting.
- Verify that the fabric is hooped securely and taut. Loose fabric can cause needle deflection.
- Inspect the rotary hook for damage or misalignment that could be striking the needle.
- Check the needle bar height and depth. If too low or too high, it can cause collisions. Refer to your machine manual for correct settings.
- Examine the presser foot for damage or incorrect height that might be causing the needle to strike it.
- Check the machine timing. Incorrect needle bar-to-hook timing is a common cause of needle breaks. This often requires professional adjustment.

4. Trimming Issues (Not Cutting or Poor Cut) medium likelihood
How to tell
Threads are not cut cleanly after a trim command, or the machine reports a 'trim error'. Threads may be left long, frayed, or not cut at all.
Fix
- Clean the cutter area thoroughly. Lint and thread scraps can jam the mechanism.
- Inspect the moving and fixed blades for dullness, nicks, or damage. Replace if necessary.
- Check the tension of the trimming belt. If it's loose, the cutter may not engage fully.
- Verify the cutter timing. If the blades are not meeting correctly, they won't cut effectively.
- Ensure the jump solenoid is functioning correctly. You should hear a distinct click when it activates.
- Check for any obstructions preventing the cutter from moving freely.
The Tajima High-Speed Plastic Cutter Assembly FD Motor for TMFX, TMEZ, TMBP-SC, TMAR-KC, TMCR Series is a common replacement.

Parts involved: Cutters & trimmers → Belts, pulleys & gears → Solenoids & magnets →
5. Machine Not Moving or Error Codes Related to Movement low likelihood
How to tell
The machine fails to start, stops unexpectedly, or displays error codes related to motor, encoder, or main shaft movement.
Fix
- Check all power connections and ensure the machine is receiving adequate power.
- Inspect timing belts for wear, looseness, or breakage. Replace any damaged belts.
- Check the main shaft encoder for proper connection and any visible damage. A faulty encoder can cause erratic movement or stopping.
- Listen for unusual noises from motors. If a motor is humming but not turning, or making grinding noises, it may be failing.
- If an error code is displayed, consult your machine's operation manual for specific troubleshooting steps related to that code.
- Ensure no physical obstructions are preventing machine movement (e.g., tangled thread, tools left on the machine).
Common culprits include the Genuine MBL S5M900 Main Shaft Motor Belt 25mm for Tajima TMAR, TFMX, TMEZ, TFW Series Embroidery Machines, or the JHX-G8L1000 1000P/R Rotary Encoder for Chinese Tajima TFMX TFGN TMEZ TMBP TMAR Feiya Ricoma Barudan Embroidery Machines.
