Thanks Roy! I took the cartridges out and shook them. That seemed to work! Next I'll work on the humidity issue. When I first got the R800, I was able to select the kind of paper it was going to print on. Now, with Snow Leopard, that option no longer exists. The only choice is paper size. Any ideas why?

I use a lot of ink cleaning clogged nozzles! If any one has a remedy for this, I'd love to hear it. > > Roger > > Roger Eichhorn Professor Emeritus University of Houston eichhorn@xxxxxx
