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.
