Confirm the machine and scope
This guide concerns the visible skipped stitch pattern, needle and thread condition, material control, design load and whether the symptom follows the same needle or area. Begin by confirming the FUJA model, serial number, controller or software revision and any accessory or configuration that affects the task.
For skipped stitches, do not apply a procedure from a similar machine merely because the symptom looks familiar. The correct model identity and document are part of the diagnosis.
- Confirm model and serial number
- Record controller or software revision
- Match the task, symptom and accessory configuration
Prepare the support record
Before changing settings or parts while investigating skipped stitches, preserve the current machine state. Collect model, controller, needle, thread, material, backing, hooping, design file, front and reverse sample and symptom video.
For skipped stitches, record when the issue began, whether it is constant or intermittent, what changed beforehand and which actions have already been attempted. This prevents repeated adjustments from hiding the original symptom.
- Keep clear photographs or video
- Preserve screen messages and the affected file or sample
- List actions already attempted
Safety and stop conditions
Before investigating skipped stitches, follow the power state, access limits and protective instructions in the manual for the exact machine. If the correct document cannot be confirmed, stop before touching a needle area, hook, drive, electrical enclosure or moving assembly.
While investigating skipped stitches, stop immediately if an abnormal sound or movement appears, the symptom changes, a protective area must be opened or the next action is not documented. Escalation is safer than repeating an unverified adjustment.
- Use the exact machine manual
- Do not bypass a guard or protective step
- Stop when the next action is not verified
Use the approved procedure
For skipped stitches, use the numbered procedure and result checks supplied for the exact machine and controller. Do not guess a setting value, compatibility rule or disassembly step from a general embroidery article.
While resolving skipped stitches, compare the observable machine, screen or sample result with the expected condition after each approved action before continuing.
- Follow the approved action order
- Check the result after each action
- Do not continue when the observed result is different
Verify the result or request support
The result check for skipped stitches should identify what the operator can observe on the machine, screen or approved sample. If the expected result is absent, preserve the current state and submit the evidence instead of continuing by trial and error.
An after sales request about skipped stitches should include the model, serial number, controller revision, full symptom or message, current result, actions already taken and the relevant photographs, video, file or sample.
- Compare with the approved result
- Preserve the current state
- Submit a complete after sales record
