I had the same thing happen once to a printer at work that spewed out a bunch of black gunk that hardened up...which I use to this day as a black pudding mini.Sometimes we have a number of situations where, for whatever reason, the core around which we form the tubes (almost identical to the cord on a weedwhacker) snaps, gets burnt, etc., and the melted plastic ends up pouring out of the machine in large globs...
