Model SU-100N is generally recommended for stapling 20+ sheets of 20-lb. paper or equivalent.  Model SU-100N requires that the proper size staple be used for each stapling job based on the number of sheets of paper (or equivalent material) being stapled as noted below.  In other words, you cannot use the HO-5/8 5/8" Staple to staple 25 sheets of 20-lb. paper because the staple leg length would be too long for that job. Take a look at this staple capacity chart for help choosing the best staple size for your needs.

Staple Type HO-1/4 HO-3/8 HO-1/2 HO-5/8 HO-11/16
Capacity* Up to 20 Sheets* 20-50 Sheets* 50-80 Sheets* 80-100 Sheets* 100-120 Sheets*
