In perfect condition, you could probably get 7k to 9k on the high end. We sell a lot of SP300V printers used which is the same model just 30". Out of the last 4 or 5 I would say that the average going price was around 5K. These printers we sell are refurbished to factory standards and in perfect working condition. Your printer being 54" adds a lot of functionality as far as size goes which gives it more value than the SP300V obviously but the fact that you can go buy a brand new printer for around 10k brings the value down significantly.
