A heat sink roller ( 34 ) is provided as part of a fuser apparatus ( 10 ) to reduce or eliminate thermal transients of a heated fuser roller ( 12 ). The fuser roller ( 12 ) is normally heated to its standby setpoint temperatures. Before the start of a copy run the heat sink roller ( 34 ) is moved to contact fuser roller ( 12 ), causing a temperature gradient due to thermal load placed on fuser roller ( 12 ). Once the run setpoint temperatures are reached, heat sink roller ( 34 ) is removed from contacting fuser roller ( 12 ), and receiver members ( 16 ) are passed through the fuser apparatus. When the last receiver member passes through reproduction apparatus, heat sink roller ( 34 ) moves to once again contact fuser roller ( 12 ) and return it to the standby setpoint temperatures.
