I haven't read about clogs specifically from compatable carts on the ip4500, but the chip transfer issue wouldn't be my favorite way to go. I would buy good quality refill ink and refill OEM carts. After several refills you can purge the carts and they will again work like new for a new series of refills. Best to have a spare set that is always filled so you can replace them quickly and refill at your liesure.
