n • The procedure explained here is the same for replacing an old BJ cartridge with a new one, or
simply exchanging the BJ cartridge for one of the optional BJ cartridges.
• Do not replace the BJ cartridge while the unit is printing or performing another operation.
• You only need to replace the Colour BJ cartridge when the print head is damaged or when you
have printed approximately 2000 pages. If ink runs out in the Colour BJ cartridge, you can
replace the individual BJ tanks (colour or black) without having to replace the entire BJ cartridge.
