EPSON STYLUS R3000 with MARRUTT CONTINUOUS INK SYSTEM

This is a used Epson Stylus R3000 with a brand-new, never used Marrutt 9-channel continuous ink system, which I have not opened or installed. The printer was not mine, but belonged to an architect and photographer who lived up the street and has moved to Europe. I have a perfectly good little inkjet printer and this thing is kind of a behemoth! It is a tool for the serious photographer or fine artist (I am neither!). CONDITION -- Some of the nozzles are clogged. I have improved the situation with some "Magic Bullet" nozzle cleaner from Marrutt, but it is not yet perfectly clean. Yellow, Magenta, and Cyan are perfectly clear, Black is almost clear, but the others are partially blocked. I have attached a photo of the nozzle check; you can barely see the Light Magenta, Light Cyan, Light Black and Light Light Black. You will have some work to do to get it working perfectly. I will give you the rest of the Magic Bullet cleaner. The reason you want the continuous ink system is that Epson no longer makes the #157 ink cartridges for this (though you can find them on eBay). The printer includes all the very-nearly-empty original ink cartridges, as well as the unopened, new continuous ink system. I have also bought a package of 3rd party ink that is currently installed (I paid $80). I plugged it into my PC with a USB-A to B cable. I was able to turn the printer on and it lit up and looked fine. I downloaded and installed the driver and software successfully on my Windows 11 PC. I did multiple nozzle checks and head cleanings. As far as I can tell, the printer works fine except for the clogged nozzles. Note that the dimensions I give are for the printer itself. The continuous ink system is in a separate box.
