The two previous posts by Some Guy and KeithR illustrate the reason for my frustration - Some Guy says I need them, Keith says, in his case, he did not.
Jon Cone in his post here said all I needed was the carts and the ink, so, either I am to assume that I do not require the chips, or, he assumes that I know about having to use the old chips (which I do not have).
Dave, I am on the other side of the world, so phoning is not an option. I sent Dana a detailed e-mail asking, point-for-point, to address some of my uncertainties. The e-mail was forwarded to Wells who sent me a pro-forma invoice/estimate for carts and ink without one of my queries being answered. Unfortunately my experience of their helpfulness has not been the same as yours.
The reason I am being such a pain in the ass is that I would hate for them to ship my order out here to South Africa, only to find that a) I can't get started immediately because I need something they assumed I had or thought I knew, and b) the cost of having to ship something out to me because of "a".
A simple "Getting Started" or similar section on their website explaining precisely what one needs to purchase, what one is expected to have, what is absolutely necessary, what options are recommended and so on - all in one single document - would, I am sure, be a good idea.
Honestly, if I had not already bought the printer, I am pretty sure I would have given up by now! I have sent Wells another e-mail asking specifically about the chips and look forward to a reply soon.
Hopefully I can get my order finalised and start printing!
Thanks for all the information!
