I've just replaced my Canon ipf6300 with a 6400, thanks to an unfixable banding problem (long story), and have a few questions for anyone who may be familiar with transferring existing ink cartridges from the 6300 to the 6400:
1) Naturally, I want to use the existing ink in the new printer. Most cartridges are 60-80% full, but a few show 20%. Given that it takes a fair amount to fill the lines at setup, is it better to begin with the new starter cartridges (for those colors presently showing 20%) rather than use the old inks and then additionally have to install the new starters if the old ones run out during setup?
2) If I don't use the old "20% remaining" cartridges during setup, can I still use them later, or will they become dried out?
3) If I sell the old printer for parts (it works fine other than very slight banding on solid patches of dark grey), do I need to purge its ink via "Move Printer", even though I'm going to pull out all of its ink cartridges?
4) I very recently replaced both print heads on the 6300, which didn't solve the banding problem. Is there a way to rescue and store them, perhaps resealing them, or is that another $850 down the drain?
Thanks!
