Troubleshooting Quick Reference

Paper drift or breaks：Check parent-roll edges, roller alignment, tension settings and sensor signals; adjust one factor at a time.
Uneven roll hardness：Check diameter-based tension compensation, brake response and rider-roll pressure.
Uneven cutting：Check blade wear, blade position/locking, dust and blade lubrication.
Counting errors：Clean sensors; verify sensing distance, pulse signal and stable feed speed.
Noise or vibration：Reduce speed and stop promptly; inspect bearings, fasteners, belt tension and rotating balance.
