It can get worse! First, IF you can get them to fixate, you're ahead of the game. Second, after you broke your knuckles and "donated" a pint of blood to the cause and finally successfully fixed them, they spread all over the pages you printed. Not very professional. I can't hand my invoices to my customers like an inkblot test! I won't buy them again. Remove the cartridges from my printer and they will NOT unlock! I should have known there was even a problem when they were SO difficult to snap into place. Now I have to completely replace my printer.
