Stack alert lights can be added to the automatic pressure sensitive labeler to allow for quick and easy reference of the labeler's functioning.  Packaging line operators can monitor the labeler from a remote area with the use of the stack alert lights.  Alert lights will activate whenever the labeler encounters a problem, such as low labels on the roll, container back ups or container jams. 

The stack alert lights allow for quick and easy troubleshooting and label replacement without continuous monitoring of the labeling machine.
