Epson Stylus PRO 10000CF Startup Manual page 16

Do not dismantle the ink cartridges or try to refill them. This
could damage the print heads.
Store ink cartridges in a cool, dark place.
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.
Do not touch the green IC chip on the side of the cartridge.
This may affect normal operation and printing.
In this ink cartridge, the IC chip retains a variety of cartridge
related-information, such as the amount of ink remaining, so
that a 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. Note that there is a valve in the
ink supply port, making covers or plugs unnecessary, but care
is needed to prevent the ink from staining items that the
cartridge touches. Do not touch the ink cartridge ink supply
port or surrounding area.
When choosing a place for the printer
Place the printer on a flat, stable surface that is larger than the
printer. The printer will not operate properly if it is tilted or
at an angle.
Avoid places subject to rapid changes in temperature and
humidity. Also keep it away from direct sunlight, strong light,
or heat sources.
Avoid places subject to shocks and vibrations.
