There is either very very little ink in these cartridges or it dries up. I am constantly buying ink and changing cartridges and I don't print very much. I almost never print a photo, mostly just household business papers and online receipts and I use gray scale unless color is necessary.
This review is mostly for the service I received from Staples which was FAST!!! I didn't really need the product "in a hurry" but I was amazed at how quickly I received it.
The Canon Gray Ink Cartridge is just what it says, an ink cartridge. Nothing special to rave about, it does what it's supposed to do. The price for this item is competitive which saved me a lot of hassel from running around from one store to the other looking for this item.
Because Staples service was so fast, I may be tempted to order online with them again.
