The label photocell transmission notes the label length and controls the labels during the printing
corresponding to the transmission principle. The labels must have gaps between the labels and the
gaps have to be different from the label.
The level of the label is set by the potentiometer P1. The measured label of the photocell is indicated
in the service functions menu ('DLS'). The setting of label level has to be > 3V (e.g. 0,3 onto the
supporting paper and 3,5V onto the label). As the smallest value it is possible to use a level of 1V.

The label photocell transmission notes the label length and controls the labels during the printing
corresponding to the reflexion principle. The labels have to be white (reflecting). The marking which
separates the labels has to be black matt (not reflecting).
The level of the label is set by the potentiometer P2. The measured value of the photocell is indicated
in the service functions menu ('RLS'). The setting of label level has to be > 2,5V (e.g.1V).
