Speed and operation
Each of the iP8500's colours can be replenished separately, so you need only replace the hues that a built-in optical ink-monitoring system determines are empty.
Canon describes the printhead as the world's longest, with the highest nozzle density: 768 nozzles per colour, for a total of 6,144. All those tiny nozzles allow it to spit out droplets of ink at 4,800x1,200dpi in each pass, accounting for the 3.5 pages per minute text speed and 0.6 photo pages per minute in our tests.
Overall, the Canon Pixma iP8500's output looks excellent, with a broad dynamic range and sharp detail rendering in bitmaps. It renders excellent curves and sharp text on coated paper, making this a good candidate for proofing page layouts.
We picked up the gauntlet thrown down by Canon and tested its output with photos of ripe red tomatoes, a carved pumpkin and lots of scenes with foliage. The iP8500 really does produce a surprisingly full range of tones in the reds and oranges, as well as lots of detail in both shadows and highlights in landscapes dominated by grass, trees, and other greenery.
If anything, saturation for these tends to be too brilliant; if you don't want the colours to assault your viewer, you might want to tone things down with your image editor. Skin tones are warm but acceptable and relatively accurate. Oddly, the cyan primary looks more like turquoise, while colours tend to shift slightly under different light sources.
