You should calibrate a substrate type before creating its color profile; however, you can later recalibrate
without needing to recreate the color profile.
Color profiles
Color calibration provides consistent colors, but consistent colors are not necessarily accurate. For instance,
if your printer prints all colors as black, its colors may be consistent but they are not accurate.
In order to print accurate colors, it is necessary to convert the color values in your files to the color values
that will produce the correct colors from your printer, your inks, and your substrate. An ICC color profile is a
description of a printer, ink, and substrate combination that contains all the information needed for these
color conversions.
These color conversions are performed by your Raster Image Processor (RIP), not by the printer. For further
information on the use of ICC profiles, see the documentation for your application software and for your RIP.
Substrate-advance compensation
Accurate substrate advance is important to print quality because it is part of controlling the proper
placement of dots on the substrate. If the substrate does not advance the proper distance between printhead
passes, light or dark bands appear on the print, and there may be an increase in graininess.
The printer has a substrate-advance sensor and is calibrated to advance correctly with most of the
substrates that appear in the Internal Print Server. When you select the type of loaded substrate, the printer
adjusts the rate at which to advance the substrate while printing. However, if you are using a custom
substrate or not satisfied with the default calibration of your substrate, you may wish to change the
substrate-advance compensation. See
Troubleshoot print-quality issues on page 231 for steps to determine
whether substrate-advance compensation will help you.
In general, substrate-advance calibration is recommended when you see print-quality problems related to
paper advance, or when you define a new substrate.
While printing, you can view and change the substrate-advance compensation of the currently loaded
substrate at any time from the Internal Print Server by selecting the print job and then the Printing Adj.
button, or by selecting Printer > Printing adjustments.
Alternatively, you can open the dialogue from the Print adjustment button in the Internal Print Server,
available under the Cancel All button on the left of the screen.
If you prefer the print quality after changing the figure in the Advance field, press the Apply button, and
thereafter your preferred substrate-advance compensation will always be used for that particular substrate
type. The selected value does not have to be the same for all substrates.
If you are using a generic substrate preset, you are recommended to clone the preset (Substrate > Clone)
and work with that before adjusting the advance compensation, so as not to alter the generic preset. See

a substrate preset on page 57.
The substrate-advance sensor may not work correctly if it is dirty. See
Clean the substrate-advance sensor
on page 178.
If the sensor was dirty, after cleaning it the advance compensation already calculated may not be valid, so
you are recommended to set the advance compensation for this substrate to zero and check that the advance
