So, full story as I think it happened.
Some numbskull decided to plug the vent holes on my carts.
Then "hey, the film printed really lightly."
Hmm, maybe a head cleaning. Yeah, that did it.
Then, "hey, the film isn't printing right again and it says low ink" (though no carts show it because they are refills)
Hmm... Oh crap, who did this?! (Discovering all the vents plugged up)
Unplug them and run a head cleaning all starts well again.
Now it's Monday and it's doing it again. Head cleaning didn't fix it this time and it might be the fourth time not the third time.
Any ideas why this is happening?
I print one cart and the others just have ink in them.
