Yet again last night my 5000 refused to print. Eventually I had to unplug it when the vacuum wouldn't turn off but nothing else would happen. On plugging it in this morning, it once again tried to do an initial fill (which of course uses a vast quantity of ink). I really am getting fed up with it (fortunately on the Canon wiki there are instructions for bypassing the initial fill). If it weren't for the expense and for the excellent quality of the prints, I would have drop kicked it a long time ago.
I would be very leery of buying the newer Canon printers given the problems of dud cartridges and heads and Canon not covering them and the risk that the interface isn't any better - too bad they messed up an excellent printer.
I'm thinking that in the long run, I could use my 4000 and 7600 for big prints (which are generally not on glossy paper anyway) and pick up a 3800 and dedicate it to gloss prints. It would be slower than the 5000 but I'd be extremely surprised if it were anywhere near as much hassle.
as an aside, was given a sample pack of the Gold Silk Ilford paper and looking forward to trying it (after I stop kicking the 5000).
