■ Replacing ink cartridges
In this section we show you how to handle and replace the ink
cartridges.
Handling ink cartridges
BJ Cartridges and ink cartridges should be used within six months of
purchase to ensure optimum printing. To avoid leaking or drying,
follow these simple precautions:
• Never attempt to disassemble an ink cartridge.
• Never shake an ink cartridge.
• Never unpack an ink cartridge until you are ready to install it.
• Do not remove ink cartridges from the BJ Cartridge unnecessarily.
• To prevent drying out the print head, never use the print head unit
with an ink cartridge missing.
• Always install an ink cartridge as soon as you remove the protective
cap.
• Keep unused ink cartridges out of the reach of children, and discard
used ink cartridges immediately. If spilled, the ink is difficult to
clean.
