Flexo Die Cutting Machine Troubleshooting Guide by Keshenglong&Shinko

Overview: Fast, Practical Diagnostics

As an industry leader since 1995, Keshenglong (merged with Japan Shinko R&D in 2017) provides this concise flexo die cutting machine troubleshooting guide to help operators quickly identify faults on flexo printers and computerized high-speed flexo slotting die-cutting machines. Built with imported Japanese parts and on-site Japanese technician standards, our machines demand precise, practical diagnostics.

Common Issues & Quick Fixes

Jamming, misregistration, poor cut quality, and inconsistent impression are the most reported problems. For jams: stop the machine, check die alignment and web tension, and inspect suction or vacuum systems. For registration issues: verify servo calibration, sensor alignment, and cylinder timing. For poor cuts: inspect die sharpness, anvil condition, and pressure roller settings. This guide prioritizes safety—always follow lockout/tagout procedures before inspection.

Maintenance Best Practices

Routine maintenance prevents 80% of downtime. Recommended tasks include daily cleaning of impression cylinders and sensors, weekly lubrication of bearings, monthly belt and servo checks, and scheduled inspection of blades and anvil surfaces. Use genuine Keshenglong&Shinko replacement parts for consistent performance across our 1–6 color and jumbo-size machines.

Advanced Troubleshooting & Diagnostics

For electronic faults, consult the PLC and servo logs: power fluctuations, encoder errors, and motor alarms typically indicate wiring, grounding, or encoder misalignment. Our machines feature user-friendly diagnostics; follow the on-screen fault codes in the operator manual to isolate root causes quickly.
