The following procedure describes how to replace the BC-21 Color BJ Cartridge
with the optional 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 optional 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 4-18) for instructions on how to replace an ink 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.
The printer beeps and moves the cartridge holder to the center of the
printer.
The power light blinks while the cartridge holder is positioned in the center
of the printer.
