AutoCAD Map 3D :: Raster Images Not Plotting?

I normally am a Civil 3D person.  Learning something new as the company I work for has been tasked with creating some GIS maps for a client.  Still have only a couple of months experience with Map 3D.  The current task at hand is creating a map of our client's district boundary to replace an old exhibit hanging in client's office.  I used mapiinsert to insert 64 MrSID raster images, then data connected some SDF file for the boundary, major thoroughfares, and tributaries.  The overall aerial imagery, after clipping, is about 11 miles by 17.25 miles.  I am planning to plot this on a 48" x 76" sheet of paper at a 1200 scale.

The problem is that I get about 1/8" of an aerial image and 75-3/4" of blank paper when I try to plot.  I have tried to reduce the raster image quality and bumped up the Rasterpercent and Rasterthreshold system variables to their maximum settings with no improvement.  Images show when I do a preview, but do not plot out.  I also tried creating a PDF but I get the same result with a thin strip of aerial when I do that.  I use Bluebeam for PDF.

Computer:

Intel Core i7 processor

8 GB RAM

Windows 7 Professional 64-bit OS

Plotter:

HP Designjet T1100ps with optimized driver

Yes, I know the HP is only a 44" plotter, but I am plotting to fit a 36" roll so that we can view a check plot before we forward the file to our reprographics company for full size plots.  I have also tried different settings on the plotter but nothing I have tried has had any impact.
