I don't understand it being a step backwards. The RF-640 looks to be the same printer I've had now for 5 years...the VS-640. It looks to have to same chassis and build as well as the same print head, which I'm having trouble with now. The True VIS VG 540 has different print heads, (which may be an older style print head, not sure) and a new ink which comes in 500ml size for the same price as the 440ml I use now. I'm not sure if this ink is as good as the Eco-Sol Max I currently use or not. I'm wondering if I should just spend the $3,000 - $4,000 to get my VS-640 back to like new condition. I'm thinking of worst case ie. print head, dampers, encoder strip, cut strip & labor. Or, I buy something new and replace parts on the old one myself. If I get it working we could use it as a backup or for helping with productivity of the occasional high quantity job that comes in.
