I cross-posted this message on the "Digital Black and White" list for those who do a lot of inkjet printing. Colleagues, I have a section on my web page about an alternative to CIS (continuous ink systems). It is a topping-off procedure that you may find just the ticket especially if you switch among several ink sets. It costs just a couple of bucks more than empty carts and is cleaner and faster than refilling. Look in the "Digital Darkroom" section at the bottom of my home page. AZ Build a Lookaround!
