HP DraftPro Plus Plotters - Drawing Is Shifted or Accuracy Is Off
There is a shift in the drawing as it is being plotted out, or lines do not meet when they should on the HP DraftPro, DXL, and EXL plotters.
Determine if the accuracy or line offset problem is in the vertical direction or the horizontal direction. Typically, if the problem is in the vertical direction, it is a problem with media expansion. Some papers are more subject to expansion than others are. If expansion during the plot is suspected, try conditioning the paper by letting it drape over the top of the HP DraftPro plotter for awhile. It will then do most of its expanding prior to plotting. Another way to troubleshoot is to load the HP DraftPro plotter with suitable polyester film and then plot. Polyester film is very stable and not subject to much expansion. When using film, if the shift is usually seen in the horizontal direction, the problem may be with the plotter itself and will require service.
