Epson STYLUS PHOTO R300 Series Operation Manual page 12

❏ Do not dismantle the ink cartridges or try to refill them. This
could damage the print head.
❏ After bringing an ink cartridge inside from a cold storage site,
allow it to warm up at room temperature for at least three
hours before using it.
❏ Store ink cartridges in a cool, dark place.
❏ Do not touch the green IC chip on the back of the cartridge.
Doing so may prevent normal operation and printing.
❏ The IC chip on this ink cartridge retains a variety of cartridge
related-information such as the amount of ink remaining, so
that the cartridge may be removed and reinserted freely.
However, each time the cartridge is inserted, some ink is
consumed because the printer automatically performs a
reliability check.
❏ If you remove an ink cartridge for later use, protect the ink
supply area from dirt and dust and store it in the same
environment as the printer. A valve in the ink supply port
makes covers or plugs unnecessary, but the ink may stain
items that come into contact with this area of the cartridge.
Do not touch the ink supply port or the surrounding area.
