Label Profile
Function not available at A2+ !
The
Label profile
function carries out a longer label advance. It saves the values measured by the label sensor
here and then prints them out in two diagrams. The printout is used to check label detection in conjunction with
the optical properties of the label medium. The printout occurs using the heat level and print speed specified in the
Setup > Print param.
menu.
i
Notice!
The printout of the diagram occurs without taking the label gaps into consideration. This is why endless
media are most suitable for the printout.
Select the label sensor to be tested in the menu
Setup > Print param.
(
"4.1.3" on page 16).
Load the label medium to be tested into the printer.
Press the
menu
button.
Select
Test > Label profile
print menu.
Start the function with the
button.
The printer performs a longer label advance. The label sensor measures the transparency/reflection capacity of
the label material here. The message
Test print OK
appears in the display once the advance is complete.
Insert printable medium (labels, endless paper) which extends across the entire printing width.
If the printout is to occur using thermal transfer printing, insert transfer ribbon with the maximum width.
Start the diagram printout with the
button.
The following figure shows an example label profile. The top diagram shows the gradient determined for label
detection. The rise (first derivative) of the gradient is represented in the bottom diagram. The starting end of the label
is located at the point where the rise of the gradient exhibits a minimum (see vertical dotted line).
