I've spent years on beverage canning floors, and the same changeover mistakes show up at almost every facility. Here are the top 5 I see — and what to do instead.

1. No standardized changeover checklist

Every operator does it differently. That variance alone can add 15-30 minutes per changeover. Document the fastest operator's method and make it the standard.

2. Waiting for maintenance to show up

If your operators can't handle basic size-change adjustments themselves, you're losing time every single run. Cross-train them on the mechanical basics.

3. Not pre-staging materials

Lids, labels, and cans for the next run should be staged BEFORE the current run ends. Sounds obvious, but I still see crews scrambling after the last can comes off.

4. Ignoring the filler-to-seamer handoff

This is where most hidden downtime lives. If your seamer isn't dialed in before the filler starts pushing cans, you're going to jam and lose 10+ minutes recovering.

5. Skipping the post-changeover audit

Run 50 cans and check seam quality, fill levels, and label placement BEFORE ramping to full speed. Catching a problem at 200 CPM is a lot cheaper than catching it at 1,200.

I teach maintenance techs and line engineers how to eliminate these kinds of issues systematically inside Line Speed Academy.
