Digital BW, The Print

I could not get a clear "experienced" reply to my query : US manual 
says one should not use the build-in cutter with rolls of fine art 
papers including Epson USFA. European manual does not mention it and 
European support team... does not know !!!

Anyone having a feedback on this please. I can't see the problem unless 
the head can't move on due to the paper thickness, but I doubt...

Thanks.
