My husband's printer showed it was out of ink, so I ordered a large size in black. Still, the printer would not work and showed it was still out of ink. Although we almost never print in color, I ordered the three color cartridges (is there somewhere I could have learned which colors, specifically, were empty?), and, at considerable expense, now have the printer up and running.
The price is ridiculous compared to the amount of life you get from them. The product delivers great colors and performance, but seems a bit steep in price.
