Notes on ink tanks
Important
• Install replacement ink tanks promptly. Do not leave the machine without ink tanks installed.
• Replace empty ink tanks with new ones. Installing used ink tanks may clog the nozzles. Used ink
tanks may also prevent correct notification of the ink tank replacement timing.
• Do not remove installed ink tanks and leave them outside the machine. In this state, ink tanks will dry
out, which may prevent correct operation when they are reinstalled. To maintain optimal print quality,
use up ink tanks within six months after you install them.
Note
• Color ink may be consumed even when printing black-and-white originals, or when black-and-white
printing is specified.
All colors of ink are also consumed during standard and deep print head cleaning to maintain
performance. When ink tanks run out of ink, promptly replace them with new ones.
