Dell AIO 962 how many pages?

I made a mistake last time I bought a printer, I chose a printer who printer cartridge is real cheap. Bad way to approach. Yeah, they are cheap but prints very few pages.

I like the autodocument feeder feature on the 962. I wanna know how many black and white text pages I can expect from the black cartridge. Also, Is autodocument feeder reliable?....Does it jam alot?
