ABSTRACT:
An assist mechanism for installing a web-type media supply into an imagesetter allows a single user to automatically lift and position a large format media supply cassette containing a supply roll from a reloading location remote from the imagesetter to a docking location in the imagesetter. The assist mechanism comprises a roll-up cart having a support bracket mounted on the top a telescopic column with two arms for supporting the supply cassette. The cart is positioned adjacent to the remote location at which time a foot switch on the cart is used to actuate the telescopic column to vertically raise and lower the support bracket. The bracket arms hook under the ends of a supply roll bearing supporting the supply roll, to lift the media supply from the surface. The cart is then rolled to the docking location of the imagesetter and the assist mechanism is actuated by the foot switch to vertically adjust the telescopic column supporting the support bracket. The media supply is then positioned into a support tray at the docking location. When the media supply is sitting in the tray, the bracket arms disengage from the end pins and the cart is rolled away. The media supply is then automatically positioned for use by the imagesetter, The assist mechanism is also be used to remove the cassette from the tray in a similar manner.
