HP Latex 3000 Printer - Manual (Page 136)

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 fine-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 suffering print-quality issues that are caused by the substrate
advance, as explained in
Substrate-advance sensor check on page 267 . To obtain the right value faster and
more accurately, see the following table:

Calibrations specific to one substrate preset
Some calibrations that the printer performs are specific to the substrate preset in use at the time the
calibration was performed and some are not. The calibrations that are specific to one substrate must be
performed again if the substrate or preset is changed. Shown below are the calibrations showing which ones
are specific 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 significantly (different thickness, etc.), then the printheads should be realigned.
● Substrate Advance Compensation: This is specific to each substrate preset.
● Color Calibration: This is specific to each substrate preset.
