A customer reported: ‘Since yesterday evening, the system has been rejecting far too many parts – even though we haven’t changed anything.’ The cause lay not in the software, but in a minor adjustment:
The lighting had been slightly misaligned following a clean.
This altered the contrast in critical areas.
The result: more parts fell outside the tolerance limits.
During the service call, the lighting was readjusted correctly and the original stability was restored.
Key takeaway: Even minor changes to the environment should be documented and – where possible – assessed together with the system partner.
