2.5.2. Error message: label error
Possible reasons of this error message "Label error" are the following:
Too thick res. opaque backing paper
In this case the value of A will be too high. This means, that the printer cannot distinguish between
label and backing paper.
Very thin labels
In this case the value of E res. B is too low, so the printer cannot distinguish between backing
paper and labels.
Pre-printed label with strong differences in contrast
Pre-printed labels are a particular problem. Here the fluctuations of voltage on the label while
measuring are very high. In this case the value of B will be very small. In case the difference
between B and A is too small, the printer is not able to measure the label.
