I. Strictly Follow Standardized Troubleshooting Procedures
1. Adhere to the principle of "external before internal, easy before difficult": prioritize checking alarm codes, visual condition, and basic air/power supplies before blindly dismantling core components.
2. Proceed in the order of "visual inspection → manual testing → instrument testing" to avoid skipping basic steps and jumping straight to deep disassembly.
II. Establish a Mechanism for Prioritizing Parameter Verification
1. Retrieve historical operating parameters before troubleshooting; compare current settings-such as tension, blade gap, and edge-guiding thresholds-against the standard process specifications.
2. Attempt to verify the fault through parameter fine-tuning first; only proceed to dismantle mechanical components if this proves ineffective.
III. Standardize the Process of Part Replacement and Verification
1. Perform signal checks using a multimeter or oscilloscope before replacing parts; proceed with replacement only after confirming the component is actually damaged.
2. Conduct single-step functional tests after installing new parts; verify normal operation before proceeding to integrated system debugging.
IV. Implement Closed-Loop Verification and Traceability Management
1. After troubleshooting, 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 and clearly define standard troubleshooting paths for various faults to minimize human error.
2. Post troubleshooting guide cards specific to the machine model nearby, allowing operators to quickly consult them on-site.
