## Question

How much does legacy edge sensor calibration cost annually?

## Short Answer

Plants using legacy edge sensors typically spend $25,000-$75,000 per line annually on hidden costs including calibration labor, extended changeovers, and quality escapes.

## Detailed Answer

The cost of continuing with legacy edge sensors includes:

#### Hidden Costs (Uncounted but Real)

- Calibration Labor: 2 hours monthly at $60/hour = $1,440/year per line
- Extended Changeovers: 2 extra minutes × 5 changes/day × 250 days at $1,000/hour = $41,700/year
- Troubleshooting Time: 4 hours/month diagnosing drift-related issues = $2,880/year

#### Risk Costs

- Quality Escapes: Undetected edge drift causing coating misregistration
- Equipment Damage: Missed edges leading to web wraps and bearing damage

#### Opportunity Costs

- Material Limitations: Cannot run clear films, mesh, or specialty materials
- Speed Constraints: Slow sensor response forces reduced line speeds

**Typical Annual Cost of Inaction: $25,000 - $75,000 per line**
