Claims
- 1. A document reproduction machine of the type having a moving photoreceptive surface; a charging station for placing a charge on the photoreceptive surface; an exposure station for forming an electrostatic latent image on the photoreceptive surface; a developing station for developing the electrostatic latent image with toner particles; a transfer station for transferring the developed image to a copy sheet; and a fusing station for fusing the developed image onto a sheet media, wherein the fusing station includes an input system for advancing sheet media at a first rate, said document reproduction machine further including a sheet cutter, comprised of:
- a bi-directional drive motor;
- a motor driven feed roller for advancing sheet media toward the input system;
- a roller clutch for selectively engaging said feed roller to said drive motor;
- a buckle sensor for sensing a minimum size buckle in the sheet media;
- a motor driven sheet cutter disposed between said feed roller and said input system, said sheet cutter for cutting the sheet media when said sheet cutter is driven by a motor;
- a sheet cutter clutch for selectively engaging said sheet cutter to said drive motor; and
- a sheet media length circuit for generating a cut signal when a predetermined length of sheet media has advanced from said feed roller;
- wherein said sheet cutter clutch engages said sheet cutter to said drive motor upon the occurrence of a cut signal;
- wherein said roller clutch engages said feed roller to said drive motor when said buckle sensor does not sense a minimum size buckle;
- wherein said sheet media advances toward the input system at a second rate which is greater than said first rate when said feed roller is driven by said drive motor, whereby an expanding buckle is formed in the sheet media;
- wherein said hi-directional drive motor rotates in a first direction when said sheet cutter clutch is engaged; and
- wherein said bi-directional drive motor rotates in a second direction when said roller clutch is engaged.
- 2. The document reproduction machine according to claim 1, wherein said bi-directional drive motor stops advancing the sheet media after the buckle expands to a predetermined size.
