Don't know. I would ask the pros at B&H. I do know that the ink from a previous canon printer should have worked with my Canon TS8200, cause they are the same shape and everything, but no there is one small tip of plastic that makes previous ink not work. So ask B&H. But I would say they won't.

The Chroma Optimizer, CO, has nothing to do with the Black cartridges. CO is a clear coating and has not pigment or color.

These pigmented inks are made NOT to fade. When these inks are used with paper that doesn't have optical brightening agents you get prints that are archival that last 40+ years without fading (when not exposed to direct sunlight).

Thanks

Don't know.

As far as I know, the only printer using pgi-72 inks is the Canon Pro 10. There is no green for that printer. My i9900 used 8 inks, one of which was green. The Pro 10 substituted gray and an extra black for green, plus the optimizer. You should never put in an ink that the printer doesn't call for and wouldn't know how to use.

Don't have any cartridges about but a simple google I found a review on the website {Digital Photography Review} states around 14ml per cartridge. It's an affordable printer and prints quality is good, but not an economical printer to operate. All small printers have a high unit price per ml of operation. As soon as you replace an empty cartridge, you are going to purge some ink out of the remaining cartridges when it clears the line for the new cartridge. I've watched the ink status for the remaining cartridges deplete and give me a warning as soon as the installation of the new cartridge was complete. I would never buy a small printer like this as I only used this for commercial 8 x 10's for portfolio use only. The rest of my products are usually large 24 x 30 and up.

Complicated...but I think same image uses twice as much pigment for 11x17 than for letter size and for B&w heavily black print far more pigment will be used than for a print that's mostly light...can be shocking.
