Banding pattens on top & bottom portion with R3000 + Win7 QTR Gui

Hi all, I am trying to make digital negatives for platinum print using Win7 version of QTR-Gui (direct print ) + Epson R3000 + Pictorico TPS-100 ( 8.5 x11' transparency sheet). It is working great except one issue. I see banding patterns on top 1 inch area and probably half inch in the bottom too. Changing image data file to other one, including just step tablet does not solve the issue. When using Epson driver, the banding disappears. So I believe this is not ink head cleaning nor data file issue. The curve set up I use is based on Ron Reeder's book ( Digital Negatives for palladium and other alternative processes) Figure 23 or 24.) So the curve itself is proved to work for other printers. I saw that R2880 also has the same problem as reported below, http://tech.groups.yahoo.com/group/QuadtoneRIP/message/9745 Only way to avoid this banding looks like using a bigger sheet ( such as 13x19 ) to leave top and bottom not printed ? which is costly and not efficient... Has anyone seen this with R3000 or any other printers ? Is there anyway better to solve this issue ? Hiroshi
