Later pickup from the receiving tray. I compressed the whole sequence into transfer and made that unclear. The source-fixture pickup was not the part I saw improve.

Was the miss a sleeve seated differently in the tray, or a correctly seated sleeve being approached differently?

Hana's question comes before deciding the locator moved. Replacing a tray also changes which pockets and surfaces are in use.

The missed sleeve stands higher before approach. I have a view of that, but no equivalent view from the earlier runs. Maintenance is checking the replacement tray against the specified pocket detail.

That is enough to retain the failure without inventing its cause. Your earlier few runs don't establish whether every sleeve was seated correctly either.

Agreed with Anil. Keep the improvement as an observation under those earlier conditions, not a percentage reduction in misses.

Replacement tray has a shallower pocket insert than the specified one. It is held out of the setup. The report now separates the limited earlier observation from this identified mismatch; no claim that changing the insert has fixed the job.

Who checks the insert identity when trays return from stores? That mismatch can reappear even after this one is corrected.
