We have a Versant 2100 and a C75. All of our carbonless work goes on the C75 because it seems to screw up the 2nd BTR on our Versant, always has since new. After running carbonless we get dirty backgrounds on coated sheets. We have tried 3 different brands of carbonless and while some brands don't do this until you run more sheets, they all pretty much wreck it. Our C75 can go back and forth without issue. We also have a lot of trouble with about a 1-inch wide faint streaking down the sheet quite often when we try to run Satin/Silk/Velvet sheets. It looks like someone drug toner laced nails down the sheet. The techs throw in 2nd BTRs every few weeks and say this is the nature of the Versant, but I think there must be something else causing this. Anyone else with a Versant experience either of these issues?
