I've had this problem as well. It seems to be caused by ink spilling from the cartridges along their track. Open the lid, take a clean cloth and gently wipe the black plastic prongs & gray foam matting (would that I knew their technical names ;)) along the cartridge track. You should notice it soaking up some ink. I still haven't figured out why it's occurring, but this seems to do the trick for me. Hope it helps.
