Hi there, Are Lexmark carts more prone to failure/permanent plugging than HP? I have less than a 30% success rate with them.. most of the time when I get Lex's they're so dry nothing comes out. I do ultrasonic clean for a while, steam, suction.. and after all that I might get a test print with 50% of what's supposed to be on the page there. We get product for refill sometimes weeks after it ran out. Is there anything we can do to revive these Lexs? Particularly Lex 16s and 82s. They just seem damned near impossible to get going half the time. They just don't want to unclog or something. Thanks!
