ABSTRACT:
Apparatus for assisting in the loading of strip roll paper in a graphics drum plotter having a vacuum column disposed between a strip paper supply roller and a drum wherein insufficient space is available between the drum and the beam/writing head above it for reaching through to grasp the paper on the supply roller for pulling it through. A hook-shaped wire guide is hingedly attached through a slot in the center of the back wall of the vacuum column. The guide wire is biased by a counter weight to a position within the vacuum column and is moved out of the vacuum column through the slot from the force of paper descending into the vacuum column. The hook is shaped to guide paper being rolled off the supply roller across the space between the front and back walls of the vacuum column and to direct it into a position between the drum and the beam/writing head where it can be grasped.
