it may as well be a storage locker with some fancy piles of garbage bags and a milkcrate of comics sitting just barely in view
i'll bid $250, and most likely be my max. Picked-up, personally.
By the time I move it, bring it back, and diagnose.... my cost will have tripled without even a guarantee that I can recoup with a few usuable parts that I may find.
If you knew more about the printer, you'd get the $1500 (and then some) out of it by parting it out... assuming you could safetly remove and ship the parts you knew were working, and find buyers for it all. Otherwise, its really just a potential treasure to someone willing to put a lot of love into. New boards could cost thousands, heads are a thousand a pop, and ink dries and hardens within the system when not being cycled, often.
