My pixma MP810 never uses the big black ink cartridge - always

Customer Question

My pixma MP810 never uses the big black ink cartridge - always uses the smaller one, whether I print in colour or black and white. Can this be corrected?

Hi, thank you for contacting JustAnswer.com. My name is Russell. I will do my best to provide the right answer to your question.


I think I understand your question, but I wish to be entirely certain before I offer an answer, so I need to ask:

- What is the number on the big black-ink cartridge?
- What is the number on the smaller black-ink cartridge?

Thanks.

The big black (on the left) is 5. The small black (on the right) is 8

Big black is 5 . Small blank is 8
Expert:  Russell H. replied 3 years ago.
OK. The big black # 5 cartridge is a Canon PGI-5BK, the small black # 8 is presumably a CLI-8.

The reason that your PGI-5BK is not being used, must be because you are not printing photos much. PG stands for 'pigment', which is a different sort of black, that is used to render black or black-containing hues in photo printing.

If you print only black text printouts, pretty much, or only photos with no dark (black or black-containing) hues, then your big black cartridge won't get used up much, until it gets overly old and becomes non-functional.
