3.2 Preparing the Dispenser
3.2.1 Inserting material
Insert your label material in the machine to follow the instructions in the chapter Operation /
Threading.
3.2.2 Defining label data
For correct dispenser operation, you have to tell the machine the length of the label and adjust
the label sensor. Normally this is done automatically. For this follow the instructions in chapter
Operation / Initialise material. For initialisation of the dispenser set the printer to OFF.
There are some reasons the automatic initialisation is not possible:
y
Using another then the standard optical label sensor
y
Label material with a low contrast ratio between label and backing paper
y
Labels with holes inside the label
In this case you have to set one or both of the parameter manually. Activate the extended
standard menu to do the settings by:
y
Pressing both keys NEXT and PRIOR simultaneously
Display: CODE
y
Password CODE entering:
1 time pressing the key PRIOR FUNCTION
2 times pressing the key NEXT FUNCTION
3 times pressing the key ENTER
Display: LPIT
y
Setting the label length
Enter the LPIT function by pressing ENTER. Measure the distance from one label edge to
the edge of the next label. Enter the value in mm by using the function keys. Press ENTER
to leave the function. See also the information below.
y
Change the setting of the label sensor
If another label sensor then the Wenglor type will be used, call the CONT function and set
the value to any M006.
If the contrast ratio is low, follow the instructions to adjust manually contrast.
y
To store the setting permanent leaves the menu with the quit function. If you power off the
machine without quit all modification are lost.
y
By pressing the key FEED one label can be dispensed if you are in the parameter selection.
Setting LPIT manually
To initialise labels with cut outs such as the one shown below - the "LPIT" parameter should be
used to enter the label pitch of the label web.
All other label edges seen by the label sensor will be ignored until the distance adjusted in the
"LPIT" parameter has been fed through the label sensor.
