The finisher for this copier got tipped over in the moving process. Now I am having problems with the stapler. When the paper is supposed to be staged for stapling there is no stopper to hold the paper in position. I am at a complete loss with no experience with this model finisher and the only other one we have to look at is 60 miles away. What is supposed to hold the paper in the stapling position? I'm not sure who manufactures these units but am having a hard time understanding the manual, although it does have pretty pictures. Saddle stitching works fine. Any help is appreciated.
