I guess most of you have noticed that mutoh ink now comes in a different cartridge. if you hold an old one up to a new one they look a little different. ever since they have come out with this new cartridge when i put one in my falcon jr. i get an error message (whatever color) CARTRIDGE. if i pull it out and stick it back in, the error goes away. any ideas why this is? it has the foil sticker on it like the old ones and when i picked up CMY inks yesterday, i looked through their stock and found old style CY cartridges that did not give the error when i put them in, just the new style M did. just wandering if anyone else has had this issue come up?
