Hello GW,
I searched our knowledge base and found two article for adjusting the staple location. Create profile for adjusting staple position & create bi-fold multiple sheet stapled position. If you are still having issues after trying these steps, I suggest that you call into our support department for assistance @ 1-800-821-2797 or 1-800-835-6100.
Is there a way to adjust the location of the staples on the square fold trimmer to center them on the spine of thicker booklets?
