Digital BW, The Print

HELLO ALL,

I have two 7600 printers sitting here in excellent condition, not getting much use since the 9900 came onboard. I've been thinking of putting the MK7600 into service as a dedicated B&W printer to do some of my own work and also offer that service to my customers. The purpose of this post is to get some information that will hopefully lead me in the right direction with this conversion. It would seem that Paul Roark is now in favor of a 100% Carbon system, although I'm not sure that is available for the 7600. Also, I have quite an array of used carts and would like to know if it's possible to successfully flush and reuse them for the B&W inkset. I believe that has been done, but it's been a while since I researched that possibility. Any information that could be passed along would be very much appreciated. If I do decide to take this route it would be helpful to set forth on the right track. 

Thanks in advance.
Gary
