Canon BJC-5100 user manual Replacing BJ Cartridges and BJ Tanks

N❍ For optimum use of the BJC-5100 Series printer, be sure to install two cartridges.

❍If you install the BC-23 Enhanced Black BJ Cartridge in Holder 1, the printer will print black ink only regardless of the cartridge in Holder 2.

❍When printing on tabloid paper (11” ⋅ 17”), the printer uses only the cartridge in Holder 1. For photo-quality printing on tabloid paper, make sure the BC-22e Photo BJ Cartridge is installed in Holder 1.

Replacing BJ Cartridges and BJ Tanks

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 BJ Cartridges in Appendix A (page A-4) for details on the expected yield of the BJ cartridges.

You may need to replace a BJ cartridge or a BJ tank when either of these conditions exists:

❍You have been using the cartridge for more than six months.

❍Your printed output is not crisp and clear, and there are gaps in the characters (missing dots) even after you have aligned the print head and performed print head cleaning several times.

If you are using the BC-21e Color BJ Cartridge and either your color or black output is blank, one of the BJ tanks is probably out of ink. See the instructions starting on page 4-16 for replacing a BJ tank.
