An electrophotocopy machine has a web of copy paper that is stored on a supply reel in the machine. A pair of initial feed rollers draws the web off the supply reel and feeds the web past a knife that cuts the web into copy sheets of suitable length. The feed rollers are driven by a gear that is connected to a motor and is mounted on and carried by a lever. The lever engages the carriage in its home position to drivingly connect the motor to the feed rollers through the lever-carried gear. A spring biases the lever against the carriage so that the drive connection to the feed rollers is broken when the carriage leaves its home position. |
