Note

Do not squeeze the side of ink tanks as this may cause the ink to
leak out and stain your clothes and hands.
Do not re-attach the protective cap once you have removed it.
Once the protective cap is removed, do not touch the open ink port.
To maintain optimal print quality, use an ink tank within six months
of its first use.
Once an ink tank has been used, 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 function 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.
When an ink tank runs out of ink, replace the ink tank with a new one
immediately.
If you continue printing with an empty ink tank, it may cause the
printer to malfunction.
