Disclosed is a method for determining the fuse capability of unprinted, bond-type papers using a peel tester designed for that purpose (see the figure). This novel fuse grade predictability test is based on the surface energetics of paper that determines the fuse quality when different papers are used in the same electrophotographic printer or copier [1, 2, 3]. Using plain, unprinted paper, the adhesive force between 3M #810 Scotch Tape* and the paper surface correlates with the fuse capability of the paper. The tape is applied on the sample support wheel (a in the figure) under constant, spring loaded force (b in the figure). Subsequently, the force required to shear the tape from the paper surface without surface damage (fiber pull-off) is determined by attaching the free tape end (c in the figure) to a tensile tester.
