The printer is equipped with a sensor that determines the height
of the media surface loaded on the platen, and the printer
automatically adjusts to the optimum print head height (platen gap)
for printing.
To use this function, you need to optimize the
platen height for the type of platen you are using and the
thickness of the media you are loading. See these sections to
optimize the platen height.
Note: Always
perform platen height optimization when using the printer for the
first time or when changing between media with different
thicknesses or different platen types.
