Abstract
A plotting system (10) including a plotting device (40) for plotting on paper (52) is provided. The plotting system (10) includes a work surface (28). A supply source (50) of paper (52) to be plotted is disposed adjacent the work surface (28). A take-up roll (56) is disposed adjacent the work surface (28) opposite the supply source (50). A supply source (64) of carbon paper (66) is disposed adjacent to the work surface (28). A take-up roll (72) is disposed adjacent the work surface (28) opposite the supply source (64). Structure (60) is interconnected to the first take-up roll (56) for periodically advancing the paper (52) across the work surface (28) from the supply source (50) to the take-up roll (56). Structure is interconnected to the second take-up roll (72) for continuously advancing the carbon paper (66) across the work surface (28) from the supply source ( 64) to the second take-up roll (72) while the plotting device (40) plots on the paper (52).
