Why are there two black ink cartridges in PIXMA MX922 ?

[williampeck1958]

Pixma MX922 has two black cartridges, one's big and the other is the size of the color cartridges ? When one gets low, then I have to replace it, it doesn't "switch" to use the other one which has plenty of ink. Why is that ?

What's the point of having two black cartridges ?

I have the opposite problem.  The PGBK tank keeps running out while the BK tank never seems touched.  I get the multi-tank packets from Costco and have about 7 BK tanks that have not been opened.  How can I use up the BK tanks?

I have no idea what is wrong with canon! Luckily when the scanners and photo printers started coming out in an all-in -one, I got lucky enough and sealed towards the HP. But my sister always went for canon. Not anymore. I've got one now and you could not pay me $1 million to get another one. They are the absolute worst printer it takes the most time and money that I've ever seen. Now my sister ate some too. My HP friend gave me no probably had Q cartridges color and black and I printed all the time with my school and photos and maybe had to get ink once every three months this is insane ! Sorry for ranting.

Honestly you’re the first person I’ve ever heard that from. Usually after people use a different printer like I’ve got my dad and family to use HB, they swear off the canon. It runs through Ink insane.

Sorry I didn’t mean sound negative. But that’s great for you I hope it works out for you.

I only use regular paper and almost always select black print , but it still only uses the little black tank and not the big one. It is not dried up or plugged up.

I always use white paper and select black when I print, but it never uses the big tank. It is not dry nor plugged u.
