Hello all. I started to get a message telling me my maintenance cartridge was almost full and to prepare to replace it. I was reading on the Canon Wiki about doing your own manual cleaning of old MC and resetting machine to start brand new again. I noticed when I pulled out the MC that only the first area of pads is really saturated and heavy. The end of the MC is very light and looks as if no ink is even on those white pads. Why is this? Can I just reset machine and continue using this MC due to there being a lot of room available to still soak up wasted ink?
