Replacing the BJ Cartridge
The actual amount of ink that you use will vary depending on the print
density of a page. If the majority of your output is graphics, you may
need to change cartridges or tanks more often than when you are
printing text only. See Appendix A, Specifications, for details on the life
expectancy of the BJ cartridges.
You may need to replace the BJ cartridge or a BJ tank when any of the
following conditions exist:
❍ You have been using the cartridge for over one year.
❍ Your printed output is not crisp and clear, and there are gaps in the
characters (missing dots) even after you have cleaned the print head
at least five times.
❍ You see the CHANGE CARTRIDGE message in the LCD.
If you are using the BC-21e Color BJ Cartridge and your output is
blank, one of the BJ tanks is probably out of ink. See the next section for
instructions on how to replace a BJ tank.
The following procedure describes how to replace the BC-21e 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-21e and the
optional BC-20 Black 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 for instructions on how to replace a BJ
tank.
To replace the BJ cartridge, follow these steps:
The cartridge holder moves to the center
of the unit.
