2. The test chart is scanned by the line sensor. If the scan cannot be completed successfully, a message is
displayed on the front panel; see
Front-panel error codes on page 160 .
3. From the measurements made by the line sensor, the printer calculates the necessary correction tables
to apply to your print jobs, for consistent color printing on that substrate type.
Calibration should be done in any of the following circumstances:
● Whenever a new substrate type is introduced that has not yet been calibrated.
● Whenever you notice excessive color differences between prints. Such color differences are mainly
caused by aging and wear of the printheads, installing new printheads, and changes in substrate
characteristics between one roll and another.
You can check the color calibration status of your substrate by pressing on the front panel.
● Recommended status indicates that this substrate has never been calibrated. In this case, the factory-
default color tables will be applied to print jobs, as there is no reference state defined. After one or
more color calibrations have been performed, pressing the Reset button returns the status to
Recommended.
● Done status indicates that a color calibration has been performed successfully at least once on this
substrate, and therefore a color reference state is defined.
● Obsolete status indicates that the last color calibration may be out of date. For instance, color
calibration status is set to Obsolete whenever a printhead is replaced. The color reference state remains
defined.
● N/A indicates that this substrate cannot be color-calibrated.
NOTE: Generic substrates cannot be color-calibrated, although such substrates may be suitable for
color calibration. You can color-calibrate clones of most generic substrates.
