I. Standardize the Troubleshooting Sequence
1. Strictly follow the "outside-in, easy-to-hard" workflow: prioritize checking alarm codes, power/air supplies, and emergency stop status before attempting to disassemble core components.
2. Proceed through the steps of "visual inspection → manual testing → instrument testing" rather than skipping basic checks to jump straight into deep disassembly.
II. Establish a Mechanism for Prioritizing Parameter Verification
1. Before troubleshooting, retrieve the standard process specifications and check for parameter deviations regarding tension, blade gap, and edge-guiding thresholds.
2. Attempt to verify the fault via parameter fine-tuning first; only proceed to disassemble mechanical components if this proves ineffective.
III. Standardize the Component Replacement Process
1. Before replacing a part, use tools such as a multimeter to test signals and confirm the component is actually damaged.
2. After installing a new part, perform a single-step functional test; proceed to full-machine integrated testing only after confirming normal operation.
IV. Implement Closed-Loop Verification Management
1. After resolving a fault, conduct a low-speed, no-load test run, followed by a trial cut using small samples to verify product quality; proceed to mass production only after confirming there are no anomalies.
2. Maintain an equipment fault log recording the symptoms, causes, and resolution methods for every issue to build a dedicated troubleshooting knowledge base.
V. Implement Proactive Preventive Measures
1. Conduct regular skills training for operators, clearly defining standard troubleshooting paths for various faults to minimize human error and misdiagnosis.
2. Post troubleshooting guide cards specific to the machine model next to the equipment for quick on-site reference.
