I ended up using the basic 'load without skew check' option, but then it all too often miscalculated the paper length and I found those blue alignment lines nowhere near clear enough.
When I tried loading without the skew check I had this problem too.
About a third of my skew check loads initiate without a hitch but probably more luck than judgement.
Certainly the Epsons are easier to load but as I am quite tall I can lean over the Z3200 and load roll paper without too much effort. Maybe standing on a small box would help? Like many I don't have the space to access the rear of the printer.
Anyway a nice review Keith, practical and informative. Many reviews seem to be too good and sometimes I suspect that they are produced as an aid for selling more printers.
