Notes on handling ink cartridges

Note the following points when handling ink cartridges to maintain good print quality.

Additional precautions are required for white and metallic silver inks. See “Specialty Inks”
on page 35.

❏ Extra ink is required to fully charge the print head nozzles the first time the printer is

used.

❏ Store ink cartridges at room temperature in a location that is not exposed to direct

sunlight.

❏ To ensure print quality, use all the ink in the cartridge before the earlier of the following

dates:

❏ The expiration date shown on the ink cartridge packaging

❏ Six months after opening the ink cartridge package

❏ If you move ink cartridges from a cold place to a warm place, leave it at room

temperature for more than four hours before using the ink cartridge.

❏ Do not touch the ink cartridge IC chip.

❏ Fill all slots using ink or replacement cartridges (replacement cartridges are required in

8 and 4 color modes). You cannot print if any of the slots are empty.

❏ Do not leave the printer without ink cartridges installed. The ink in the printer will dry out

and the printer will not function as expected. Leave ink cartridges or replacement
cartridges in all slots even while you are not using the printer.

❏ Because the green IC chip contains the cartridge’s own information such as the

remaining ink level, you can still reinstall and use the ink cartridge after removing it from
the printer.
