Why according to my printers do these aftermarket cartridges deplete their ink so rapidly when I haven't even used them other than for a few test prints? I've got a WF-2630 and a WF-2760. The ones from the pic would be my second set, the first did the same thing, now two of them are useless apparently while the other two are almost completely depleted. I have another set of cartridges coming in the mail. Is it the printers or the after market inks?Aftermarket ink I bought.
