Abstract
To disengage the cleaning blade from the photoreceptor of a reproduction machine and avoid cold set and damage to the photoreceptor during prolonged machine shutdowns, a bi-metal coil spring is positioned inside the fusing roll to sense fuser temperatures, with linkage coupling the spring to the cleaning blade so that when fuser temperatures fall below a preset operating temperature, the spring relaxes permitting a weighted member to retract and disengage the blade from the photoreceptor.
