Calibrate the printhead
Introduction
When you are unsure about the density of colors on your printed output, you can optimize the
printhead performance. Perform a printhead calibration when you want to optimize colors.
When you enable [Automatic nozzle optimization] the printer will create a test print on which
each individual nozzle will print a pattern. Failing nozzles are compensated by other nozzles for all
print jobs, which results in an optimum print quality.
NOTE
• You can only perform printhead calibration when you print without winding. For more
information, see
Print without winding on page 139
.
• You have to use a media width that is larger than 1270 mm (50 inch).
• You have to use a media type that can be used for printing without winding.
• You have to use a smooth, white, opaque, non-reflective media for the printhead calibration of
one of the following categories:
• Heavy paper > 200 gsm (54 lb bond)
• Paper 120-200 gsm (32-54 lb bond)
• Film
• Polymeric & cast self-adhesive vinyl
• Thick film > 200 um (0.0079 inch)
Procedure
1.
On the operator panel tap on the [Tools] icon on the right.
2.
Tap on [Printhead calibration].
3.
Select the roll you want to use for calibration.
4. Tap on [Start].
The printer performs the calibration.
NOTE
The calibration can take quite some time, around 30 minutes. Wait until the printer is
finished with the calibration. When the active job disappears and [Start] is no longer
greyed out, the calibration is finished.
