LVS-7000 Synchronization Issue when seeing Horizontal Lines in Image

Recommended Posts

Initially reported as a synchronization issue with re-running an existing job which had worked on previous occasions.

Repeated trial of smaller & wider sync slices, as well as various positions, including slightly off web, and narrow to the point of including an area just larger than the gap between labels yielded no success.

Looking at the zoom window area, horizontal lines can be seen. A Venetian blind effect.  This caused enough interference in trying to sync properly, that resolving this condition resolved the sync issue.

Ultimately it was found that an aging power supply was causing the light to flicker just enough for the camera to notice, but not the human eye.  Replacing the power supply resolved the horizontal line issue, and a new job was created and synchronized successfully.
