ABSTRACT:
A NFFR is disclosed which does not exhibit the phenomena of droop which can occur when the fuser switches from a standby to a run mode of operation. The elimination of droop is effected using an external heat source which together with an internal source of heat supplies heat to the surface of the heated fuser member to maintain its surface temperature at a preset standby value until such time as the fuser roll core reaches a temperature level sufficient to maintain the heated fuser member surface at a substantially constant temperature during standby and run modes of operation.
