Replacing the BJ Cartridge

The following procedure describes how to replace the BC-21 Color
BJ Cartridge with the BC-20 Black BJ Cartridge. Follow the
instructions in this section to replace an old BJ cartridge or to
change BJ cartridges when you are switching between the BC-21
and any of the BJ cartridges.
You only need to replace the BC-21 Color BJ Cartridge when the print
head is damaged (or after printing approximately 2000 pages). If one of
the ink tanks (either color or black) in your BC-21 Color BJ Cartridge is
out of ink, see the next section (page 5-18) for instructions on how to
replace an ink tank.
Before starting, make sure the printer's power is on.
