I'm selling my iPF5100 as I'm moving up to a larger printer. I purchased this new only 6 months ago and it has operated perfectly from day 1. Y, PC, C, BK, PM, M and B inks (90ml tanks) have about 40% ink remaining. MBk and R (90ml tanks) have around 60% remaining and PGY, GY and G have new, full 130ml tanks. The 5100, as you probably know, produces outstanding prints in both color and b&w.
I'm located near Portland, Maine. You would need to pick up the printer at my location but if you're not located to far away, I might even consider delivering to you.
Price is $800.
