I see in your R3000 Youtube video you have a tray to hold your R3000 cartridges. Where did you obtain the tray you use to hold the cartridges? I’d be interested in such a device for both R3000 and 3880 cartridges. Many thanks,
The tray used in our R3000 video was what the Epson carts came in with the new printer. We use stackable plastic bins for cartridge storage in our R&D lab, to separate different models, and keep the carts upright.
Best regards and happy printing~ Dana
