I only use the 1800 for BW prints.The odd thing is that when I do a nozzle check,which shows a good pattern in all three black positions it ALSO records a perfect BLACK pattern in the R (red) position. After a long print session I think it clears!

Crossover is only an issue if you are actually printing with the channels it contaminates. This is usually caused by ink being sucked back up into that channel from another. Since it cleans itself out, and you aren't using that channel anyways, its not really a problem.
