I set mine to 240 minutes and haven't touched it since. I just let it go to sleep or whatever state it goes into after 240 min.
If I think I'll use the printer within the next few hours I'll tap the On/Off power button and let it go through its wake-up, clean, jiggle ink carts routine.
fyi.. Thus far, after 4 months of use, no problems with my Canon Pro-1000. I love the print quality. No complaints. None.
I use Canson Infinity (exclusively, all sizes, use Canson printer profiles for each paper respectively):
-- Photographique Baryta (310g)
-- Platine Fibre Rag (310g)
