Speed = Distance Between Photocells ¸ Time Between Photocell Triggers
1.Notes
To use a photocell encoder, ensure the "Print speed mode" of labels that are
sent to the print group is set to "External". see Label Settings on page 134.
2.
The print speed of the first label is set by the label's "Production speed (m/
min)" setting. see Label Settings on page 134.
To setup two photocell encoders:
1. If the print group is active, stop the print group. Select STOP, select the print group and
select Stop.
2. Make sure the photocell furthest away from the print head is correctly connected to one of
the controller's I/O inputs:

3.
Assign the input function of the photocell furthest from the print head to "Preceded
Product Detect", see Inputs on page 82.
4.
Make sure the photocell closest to the print head is correctly connected to one of the
controller's product detect inputs:
