Canon BJC-80 - Manual (Page 51)

Switching the BJ Cartridges
Follow these instructions to change cartridges when you want to switch from
color printing to high-speed black printing (or vice versa).
You also follow these steps to replace a used BJ cartridge. However, you only need to replace a BJ
cartridge if for some reason the print head becomes damaged (see Appendix A, Specifications, for
cartridge life expectancy). If a BJ tank is out of ink, see the next section (page 4-17) for instructions on
how to replace it. Typically, you will replace the BJ tanks in a BJ cartridge numerous times before you
need to replace the BJ cartridge itself.
Before you begin, make sure the paper support is open and the power is on.
