To maintain optimal print quality, use an ink tank within six months of
its first use.
Once an ink tank has been installed, do not remove it from the printer
and leave it out in the open. This will cause the ink tank to dry out and
the printer may not operate properly if it is reinstalled.
Color ink consumption may occur even when black-and-white or
grayscale printing is specified.
Color ink is consumed in the head cleaning and deep cleaning, which
are necessary to maintain the printer's capabilities.
