Less clogs with K3 inkset than K2.Ignore machine pleading for powercleaning and run a nozzle check. If there are a few small clogs (often, even after warning, it's clean),
run a couple of A4s through and test again. If still clogged do a nornal clean. Powerclean is for dire cases.
I turn machine off at night to park head properly. Make sure you turn off on machine , not at the wall.
Good Luck.
The 800 series are fine printers, the main bug being the cost of changing Matte Black ink to PhotoBlack and vv. I'm not convinced of the ImagePrint Phatte solution.
As Michael suggests in another post, the Canon 5000 coming soon, must be watched too, but it's early days.
Cheers,
