| False reject rate spikes after shift change |
Line slows, operators override machine, defects pass |
Remote parameter re-calibration; shift-specific lighting profile |
| New bottle design (supplier change) |
Machine rejects all new bottles; full line stoppage |
Re-teaching visit: new SKU profile built and validated in 1 day |
| Camera image goes blurry over time |
Defects start passing undetected; quality audit fails |
Quarterly PM catches lens contamination before it affects detection |
| LED lighting flicker / intensity drop |
Inconsistent imaging; false positives and false negatives |
LED module swap from Hyderabad stock; same-day dispatch |
| Expansion: 2 new lines need same machine |
Re-negotiation delays; commissioning from scratch |
Existing configuration replicated; new-line commissioning in 4 days |
| Machine is 3 years old — performance degrading |
Increased false rejects; management considers replacement |
Upgrade assessment: camera + algorithm update restores full performance |
