Why would he go through the the trouble of replacing all of those parts and then throw in the towel over a print head? That's a red flag in my book, if all it needed to be a functioning unit was a printhead you'd think he would replace the head and then sell it for a bigger profit... If the seller doesn't see the sense in investing any more into the machine then why would you? If it is worth 3300 as a
paper weight then I would think it would be worth double if it was working like new, they must not think it's worth fixing.
