Replacing the BJ Cartridge

The following procedure describes how to replace the BC-21e 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-21e and any of the other

BJ cartridges.

If one of the BJ tanks (either color or black) in your BC-21e Color BJ Cartridge is out of ink, see the next section (page 4-18) for instructions on how to replace a BJ tank.
