18 Safety Instructions
❏ Do not remove or tear the label on the cartridge; this can cause 
leakage.
❏ Install the ink cartridge immediately after you remove it from 
its package. If you leave a cartridge unpacked for a long time 
before using it, normal printing may not be possible. 
❏ Do not use an ink cartridge beyond the date printed on the 
cartridge carton: otherwise, it may result in reduced print 
quality. For best results, use up the ink cartridges within six 
months of first installing them.
❏ 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 side 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.
❏ Store ink cartridge with its label facing upward. Do not store 
cartridge upside down.
