Every time I buy cartos it seems like im doing something wrong. The first couple seem to work ok then further down the line I try and change the carto and it gets really hot like a burning hot inside. These are pre punched boges. They get so hot I can actually see the orange inside the holes from where they were punched. Are these not punched properly? I seem to get this when I order the pre punched ones. Any fix for this? Did the vendor punch them wrong? Or am I doing something wrong when I change them? All I do is change out the carto when it seems to get to clogged. I am thinking who ever punched these damaged the inside and the carto is not working properly. This throws E1 or E8 on my Provari so I know it has to be the carto... Thanks for advice.
