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 131
.
• 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)
