# IA: DTF first-week install must complete feeder+shaker+cure training

**Source:** Simply Pretty Printing urgent complaint (batch 91 / Jaco)
**Lesson:**
- Do not leave client with print-only smoke test; run metres + powder + cure with dwell guidance.
- Disclose ethernet-only + adapter/driver need before leave-site.
- Sensor/auto-feeder QA before handover; same-day return of shaker/oven = process fail.
- Recurring "outdated drivers" on tech-configured laptop → escalate human ownership, not more TeamViewer loops alone.
- Finance clients escalate to refund faster — own within first week.
