hp450c cutting off right side of plot

I have an hp450c with a 24" roll paper. When i plot it cuts off the right
side of the drawing. some times it is 1" in losing the top of my border.
other times it will go almost as far as half of the drawing. I changed my
plotstyle"pen assignments" and it seamed to go away but came back.
Is this a soft ware problem or is it the plotter that is broken? I have
downloaded updated drivers and changed the plotter cable. I had this problem
in acad2000 and now have 2002 and it still has the same problem.
anyone with similar situation or is it just me?

 

We also have a 450c with 24" roll, and never had that happen.

Out of curiosity, do you plot to extents, window, limits, or?

It could be if you are set to extents or limits that they are off - use window
instead to window the proper area.

Does the preview look correct? Does the margin dotted line in pspace appear in
the correct location?

I have plotted to extents, window, even scale to fit. and yes the preview
shows it perfect.
must be the plotter. The belt got chewed up about a year and i half ago and
I changed it myself but i think i had the problem before than, cant
remember. maybe i nocked some limits out or somthing?
