Disabling ink level monitor on Pixma MP600

[websnail]

I finally got the warnings and had to press stop/reset to disable monitoring on the PGI 5 cartridge so apparently everything is working as it's supposed to. This is on a Pixma MP600 that is about 2 months old. The X has disappeared from above the cartridge.
Thanks for the replies.
