It sounds like they may need to set their "Q" values for the labels they are using.   If that isn't it, we may need more info - are they using Zebra brand or custom labels?  
To start with, I would ask them to try adding these "Q" value commands: q456 Q152,24
If that doesn't work, then maybe they can provide the other info mentioned above so we can understand the problem better.

There are a few common reasons this is problem can exist.

1.) the incorrect template is used when creating the label

2.) the labels are installed incorrectly - the labels must be loaded and pushed against the left side of the printer and lid closed when printing to ensure the labels don't "wander" out of the sensor's view.

3.) the label sensor is covered by some debris - sometimes a label jam can cause a piece of label to become stuck on the underside of the sensor thus blocking its view.

4.) The labels are defective - if you have another roll of the same size, try it to see if it has the samme issue.
