Thanks for the responses, emailing Epson to see what they have to say about the whole situation, when I get an "offical" answer I will let everyone know what it is... not that I am expecting much to be honest. I will certainly try the sheet feed method to see if that helps.
I do set specific sizes for each print, and I get the extra margin as I want, however the silly machine still rolls out approximately 8" too much PRIOR to printing... very wasteful and annoying.
