i bet after that it still made noises!
we used to have this cannon printer. it would go through its "warm up" process, make noises waste a few pieces of paper, have a few seizures, shake the whole desk, everything. then print absolutely perfectly, for the first 1/2 of each page, the next 1/4 was readable but just barely, the last 1/4 of the page looked like something form a sci fi movie.
so we decide since it has a warrantee we'll break it and take it back. the usual hitting did nothing so the cover came off and i put a screw driver between the prongs of the big computer chip, it sparked a few times, smelled real bad so i thought i was done. i hook it back up and it works better than it did before, still not good mind you. so next i take a peizo igniter (from a bbq grill) solder on a few wires and go to work shocking the living hell out of every chip in there, that much static electicity has to hurt something, right? wrong! so next i dig out an old 12 volt back up battery for a security system and a good sized tansformer, i've been able to weld light metals with this contrption i have. i put that to the chips and you'll never guess what. the damn thing still works! sparks were flying, a few of the prongs of the main chip were totally burnt off and it still kept going. it never worked good, but anything that durable should win some kind of award.
cutting the power wire inside eventually killed it... now i have a hp hunk of garbage!
