Printhead profile

The Printhead profile function prints a diagram representing the resistance values of the individual
print points in a curve. This printout is used to check the printhead status. If a printhead is defective, its
resistance value increases. Such a print point error is reflected in the print image by a light line in the
direction of paper flow.
The printout occurs using the heat level and print speed specified in the Setup > Print param. menu.
The printout occurs without taking the label gaps into consideration. This is why endless media are most
suitable for this purpose.
1. Insert printable medium (labels, endless paper) 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. Press the menu button.
4. Select Test > Printhead profile menu.
5. Start printout with the ↵ button.
You can cancel the printout with the cancel button.
Directly below the black bar labeled Printhead profile, the printout contains a scale which marks the
actual geometric arrangement of print points. This makes assignment to the scale in the following dia-
gram possible.
Example:
Figure 16 shows a printhead profile with a print image error in the black bar at approx. 22.5 mm. In the
diagram, a print point with a clearly increased resistance value appears in the corresponding location.
This proves that the image error can actually be traced back to a printhead defect.
