Problem & answerP-11
Print in the Wrong Position on the Bottle
Also covers: Printer and side-grip conveyor not aligned
Likely causes
- Printer head height not set to the print area at the bottle bottom
- Side-grip belts holding the bottle too high or too low
- Ribbon not centred on the print head (see P-02)
- Bottle leaning in the belts (uneven grip)
- Print trigger sensor delay incorrect
How to fix it
- 1Stop the line and segregate bottles since the last good check.
- 2Set the printer head height so the code falls on the specified area near the bottom of the bottle.
- 3Set the side-grip belts so the bottle is held upright and level with the print head.
- 4Re-centre and straighten the ribbon over the head (Section 6.4).
- 5Adjust the print trigger delay so the code lands in position.
- 6Print test bottles and check position and completeness.

Code complete and in the specified position on 10 consecutive bottles.
Stop it coming back
