Worn drive chains cause pitch error and label indexing drift. Measure chain elongation and sprocket wear, and replace when the elongation exceeds the service limit.

A glue blockage stops labeling. Check the glue tank level and temperature first, then trace the supply path from tank to drum for solidified glue.

Label misapplication is usually a container guiding, sensor timing, or glue temperature problem. Check those three in sequence before adjusting mechanical label placement.
