Robuskin XTP 200 gsm synthetic paper won't print on our Xerox cp1000. After printing 1 or 2 sheets the paper stays in the paper tray. In the beginning there was a lot of static electricity, but as we fed it through an offset press, this is resolved. It is acclimatising for about 4 days, this doesn't help. Xerox technicians can't help us. Can somebody give some tips concerning synthetic paper transport?
