Since I bought this pen plotter 2nd hand, I have no manuals for this plotter and HP no longer offers manuals, I don't understand what is wrong. I am plotting county plat maps (1" = 1 mile), so the drawings are rather large. I send too the plotter thru Autocad a customized page size of 34" X 60" which previews fine, but after plotting for 3hrs straight (one map), it cuts without finishing the last 2 inches of the drawing and displays "File too Big, No frames". Can anybody enlighten me! Appreciate any help!
