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.
You only need to replace the BC-21e Color BJ Cartridge when the print
head is damaged (or after printing approximately 2000 pages). 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.
Before starting, make sure the printer’s power is on.
❍ Use both hands to grasp the sides of the cover and pull it
toward you.
