72Using BJ Cartridges
BJ Cartridge Guidelines
Always store BJ Cartridges and ink tanks safely out of the reach of small
children. If a child inadvertently licks a BJ cartridge or ink tank or ingests any ink,
consult a physician immediately.
Do not leave an empty ink tank in a BJ cartridge. Remove it immediately after ink
runs out.
To maintain optimum print quality, use up a BJ cartridge within one year after
installation and ink tanks within six months of installation.

When to Replace the BJ Cartridge

When your printed text is faint or the printed colors are wrong, print a Nozzle Check Pattern
and check the status of the print head. Based on the results of the Nozzle Check Pattern,
clean the print head and replace the ink tank or BJ cartridge if required.
