Thanks for this fast reply! I have tried to modified the border as described in the manual. Unfortunately the error has not gone or changed at all. I will contact the support to see if this is a more serious problem.
I found some documentation in the User Guide HERE on page 125 to adjust the print margins. You can give that a try to see if it helps.
If that doesn't work, there could be a hardware issue and I would recommend contacting our Support Department.
I'm using a WC6515 to print exact scaled drawing on the laser which are cut later by a cutting machine (silhouette portrait 2). After extensive testing I found that the printer has a serious geometrical distortion with a maximum of 2 mm only in the lower right corner of the printed paper. All 3 other corners are fine. I finally have printed the same test squares on another laser printer and a ink jet printer. Using different papers (80g 120g and 160g) on all three printers, the Xerox always shows this geometrical distortion. As my drawing have fine details of less than a millimeter, they are cut away by the cutting machine which is very cumersome.
Has anyone already found these problems? Does anyone know why this happens? And finally does anyone know if there is a way to calibrate my laser so it prints with less geometrical distortion (or simply to get rid of these inaccuracies)?
