Locate the lightest of the columns and enter its number as the advance parameter for the Printer > Printing
adjustments dialog. The value chosen in this example should be −3.
Afterwards, reprint the test and ne-tune: increase the value if there is a thin dark line, decrease it if there is a
thin white line.
TIP: The value used for the substrate advance depends directly on the thickness of the substrate, and needs
to be changed only when you are suering print-quality issues that are caused by the substrate advance, as
explained in Substrate-advance sensor check on page 316. To obtain the right value faster and more
accurately, see the following table:

Calibrations specic to one substrate preset
Some calibrations that the printer performs are specic to the substrate preset in use at the time the
calibration was performed and some are not. The calibrations that are specic to one substrate must be
performed again if the substrate or preset is changed. Shown below are the calibrations showing which ones
are specic to one preset and which ones are not:
●
Printhead Alignment: This is applied to all presets and print modes. Usually, when switching from one
substrate to another, there is no need to realign the printheads. However, if the printhead-to-paper
spacing has changed signicantly (dierent thickness, etc.), then the printheads should be realigned.
●
Substrate Advance Compensation: This is specic to each substrate preset.
●
Color Calibration: This is specic to each substrate preset.
