4.3 Initialise new label material for dispenser
The 720 requires data of the label material in use i.e. label length and opacity of the label and
backing material. In most cases those parameters can be scanned during automatic
initialisation. This is not always possible.
During initialisation the 720 uses its label sensor to determine where the labels are on the label
web and the distance between the leading edge of labels (the label pitch) so that they can be
positioned correctly.
There are several modes of initialisation which will be explained later, but in most cases
initialisation should be executed in fully automatic mode. For fully automatic initialisation the
"LPIT" and "CONT" parameters should be set to "AUTO". Initialisation can be executed by
pressing the whenever the message "INIT" is displayed by the machine.
The message "INIT" is displayed in the following cases:
a) if the key is pressed and held during power up
b) on return to the standard menu after the "CONT" or "LPIT" parameters have been changed
to automatic mode
c) on return to the standard menu after the configuration menu has been used
d) after clearing the error messages E__0 or E__1 in the standard menu. (If the feed key is
pressed while another parameter is displayed, the data from the last initialisation is held
and the first label edge detected is simply moved to the position defined by the "STOD"
parameter)
To start initialisation simply press the key when "INIT" is displayed.
The machine will slowly feed the label web while it searches for the gaps between labels and
measures the label pitch. When the machine has determined this information it will move the
first label edge found during the initialisation process to the position that has been adjusted with
the "STOD" parameter. After initialisation has been completed successfully ("ON") is displayed.
Initialisation can only take place in the standard menu; it is not required in the product menu
since all label data is already stored in the machine's memory. After a E__0 or E__1 message
has been cleared whilst in the product menu the first label edge detected at the next press of
the key will be moved to the position defined by the "STOD" value stored in the
machine's memory.
However, when changing to a new product bank or changing label rolls the FEED key should
be pressed once so that the label sensor can find the next leading label edge and move if to the
correct dispense position previously defined by the STOD parameter
