The leading sheet is not used when printing an ink image, but when printing the GO layer if you leave less than 2" paper margin on the lead edge of your print.
I have carefully inspected many Piezography prints made with our 3880, as well as many prints the customers have made with their 3800/3880 printers on several glossy papers, including JonCone Studio Type 5, and none show even slight traces of pizza wheel marks.
It would be very helpful if you could send me a printed example on Type 5 and Epson Luster paper, as well as an unprinted sheet of Type 5 from your box for me to evaluate. Please notate any information on the Type 5 box, such as batch#, etc... I have included my mailing address below, and will let you know as soon as I have received your samples.
