Tajima TMFX Series: Essential Maintenance Schedule & Wear Parts Guide

1. Needles high likelihood

How to tell

Frequent thread breaks, skipped stitches, poor stitch quality, fabric damage, dull or bent needle points, burrs on the needle eye or shaft. Needles are consumables and wear out with use.

Fix

1. Inspect needles before each job and after any thread break or fabric snag.
2. Replace needles immediately if they show any signs of dullness, bending, burrs, or damage.
3. Always use the correct needle type and size for your fabric and thread combination.
4. Ensure needles are inserted correctly and fully seated in the needle bar.

2. Rotary Hook high likelihood

How to tell

Frequent thread breaks, especially bottom thread breaks, inconsistent stitch formation, looping, noise from the hook area, burrs or nicks on the hook point, excessive lint buildup in the hook race.

Fix

1. Daily: Clean the rotary hook area thoroughly, removing all lint and thread bits.
2. Weekly: Inspect the hook point for burrs or damage. Use a fine emery cloth or specialized hook file to gently remove minor burrs, or replace if severely damaged.
3. Lubricate the hook race as per your machine's manual, typically with a drop of high-quality embroidery machine oil.
4. If damage is significant or performance doesn't improve after cleaning and lubrication, replace the rotary hook.
5. Ensure the bobbin case tension is correctly set after replacement.

3. Timing Belts (X/Y Axis, Main Shaft) medium likelihood

How to tell

Skipped stitches, design misalignment, inconsistent stitch length, machine making grinding or slipping noises, visible cracks, fraying, or stretching on the belt surface, loose belt tension.

Fix

1. Visually inspect all timing belts (X-axis, Y-axis, main shaft) for cracks, fraying, missing teeth, or excessive wear.
2. Check belt tension. Belts should be taut but not overly tight. Refer to your machine manual for specific tensioning procedures.
3. If any belt shows significant wear or damage, replace it promptly to prevent further issues or complete failure.
4. After replacement, ensure proper alignment and tension of the new belt.

4. Take-Up Lever Drive Crank Rod Assembly medium likelihood

How to tell

Inconsistent thread tension, looping, thread breaks, unusual noise from the take-up lever area, visible wear or looseness in the crank rod joints, jerky movement of the take-up lever.

Fix

1. Inspect the take-up lever drive crank rod assembly for any signs of wear, looseness, or damage at its pivot points.
2. Check for excessive play in the joints. If there is significant play, it can affect thread tension and stitch quality.
3. Lubricate pivot points as recommended in your machine's manual.
4. If wear is significant or adjustment doesn't resolve issues, replace the entire assembly.

5. Needle Bar Reciprocator Assembly medium likelihood

How to tell

Needle breaks, inconsistent needle depth, noise from the needle bar area, visible wear or looseness in the reciprocator mechanism, difficulty with color changes, incorrect needle bar timing.

Fix

1. Inspect the needle bar reciprocator assembly for wear, especially in the sliding surfaces or pivot points.
2. Check for any looseness or excessive play in the mechanism that controls the up-and-down movement of the needle bars.
3. Lubricate according to your machine's manual.
4. If wear is evident and causing performance issues, consider replacing the assembly.
5. Ensure proper needle bar height and timing are set after replacement.

6. Thread Block (Tensioner) low likelihood

How to tell

Inconsistent thread tension, looping, thread breaks, visible grooves or damage on the tension discs, difficulty adjusting tension, thread snagging.

Fix

1. Inspect the thread block and tension discs for any grooves, nicks, or damage caused by thread friction.
2. Clean lint and debris from between the tension discs.
3. Ensure the tension spring is functioning correctly and providing consistent pressure.
4. If discs are grooved or damaged, replace the thread block assembly to restore proper tension control.

7. Jump Solenoid low likelihood

How to tell

Inconsistent or failed jump stitches, thread breaks during jumps, machine stopping with a jump error, solenoid not engaging or disengaging properly, audible clicking but no movement.

Fix

1. Check the electrical connections to the jump solenoid.
2. Inspect the solenoid plunger for free movement and ensure it's not obstructed by lint or debris.
3. Test the solenoid's function. If it fails to activate consistently or at all, it may need replacement.
4. Ensure proper timing and adjustment of the jump mechanism after replacement.

8. USB Emulator / Floppy Drive low likelihood

How to tell

Difficulty loading designs, 'disk read error' messages, slow design loading, machine not recognizing USB or floppy disks, intermittent data transfer issues.

Fix

1. Ensure the USB drive or floppy disk is correctly formatted and free of errors.
2. Try a different USB drive or floppy disk to rule out media issues.
3. Check the connections to the emulator/drive unit.
4. If the unit consistently fails to read or write data, replace the USB emulator or floppy drive.
