A method and system for nip gap adjustment of a roller pair such as is
used in a printing device with a fusing station for fusing a substance to
a substrate and a sheet transfer path for transporting the substrate
through the device. The roller pair may be located along the sheet
transfer path after the fusing station and includes a first roll having a
first axis of rotation and a second roll having a second axis of
rotation, the second roll operatively positioned with respect to the
first roll so as to transport a substrate with the first roll and the
second roll. The device further includes a nip gap changing mechanism for
changing the separation between the first axis of rotation and the second
axis of rotation to establish a nip gap.
