• The procedure explained here is the same for replacing an old BJ cartridge with a new
one, or simply exchanging the BJ cartridge for an optional BJ cartridge.
• Do not replace the BJ cartridge while the copier/fax is printing or performing another
operation.
• You only need to replace the Color BJ cartridge when the print head is damaged or when
you have printed approximately 2000 pages. If ink runs out in this BJ cartridge, you can
replace individual ink tanks (color or black) without having to replace the entire
BJ cartridge. (1 p. 12-14)
Follow this procedure to replace the BJ cartridge:
1
Make sure the copier/fax is plugged in.
2
Lift the document guides to open the
ADF (Automatic Document Feeder).
• If it does not open easily, slide the
document guides outward and then open
the ADF (Automatic Document Feeder).
Alternatively, set the document feed lever to
a (automatic) document feed.
