Test Grid
The Test grid function prints out a geometric pattern on a background grid. This allows you to
assess the evenness of the print quality.
The printout occurs using the heat level and print speed specified in the Setup > Printing menu.
Note: The printout occurs without taking the label gaps into consideration. This is why
continuous media is most suitable for this purpose.
1) Insert printable medium (labels, continuous media) which extends across the entire printing
width.
2) If the printout is to occur using thermal transfer printing, insert transfer ribbon with the
maximum width.
3) Start menu.
4) Select Test > Test grid.
The geometric pattern is printed every 3 seconds once the Test grid function is started.
