Training should focus on repeatable operation and safe fault recovery.
Cap feeder operator training should explain how to load closures, recognise normal feed behaviour, respond to cap-low warnings, clear simple stops through the intended route, run changeovers, check first-off caps and escalate repeated faults. It should also make clear which settings operators may adjust and which require engineering support.
Training is especially important where caps can bridge, nest, scuff or tangle, and where the feeder is connected to an automatic capper. An untrained recovery attempt can cause repeated jams or make a sensor problem harder to diagnose.
