Gary,
Yes, the Canon Wide Format list at Yahoo seems to have petered-out. I can't get into the Epson one anymore because after I complained twice to the moderator about spam coming accross it, we had some words about moderating responsibility whereupon I withdrew from the list and he banned me - so end of story - I have no idea what has been happening on that list recently. Anyhow, too much on that list was consumed with issues that people could better resolve by reading the instruction manual and consulting Epson's email tech support.
I think there is nothing that prevents you and other users from starting a new thread on this Forum dedicated to operational experience with the Canon IPF 5000. This would be helpful both to those using the printer and those who are interested in that experience, in order to decide whether or not to buy one.
Henk,
Yes, these printers are supposed to be announced in conjunction with Photokina. They will be pigment ink, archival printers in various dimensions. I have not been told what the exact model sizes will be, because that is still proprietary information, but it is factual and mentionable that they will be announcing these new models. They will be able to handle a wide variety of media, and I am told they will have many other sophisticated features, but I don't know the details because that is also still proprietary. I agree HP is best known in the public at large for office type machines. However, it so happens that HP has been manufacturing very large format printers for commercial imaging that produce stunning results. They tend to put high quality machinery on the market, so I am very hopeful about these new entrants. I am now using an Epson 4800, which I like very much except for two issues: the paper switching problem and clogging; but I shall not replace it until I see in detail what HP is coming-up with and whether Canon produces fixes for the issues already identified with the IPF5000. I am reliably informed that Epson will not be changing anything on the 4800 model, but they are being very tight-lipped about whether or when they will have a new model replacing it.
