Abstract
Mechanism for latching a backup roll into engagement with a heated fuser roll structure. The mechanism is characterized by a four pivot linkage including a first fixed pivot supporting the backup roll for movement. The linkage is so arranged as to require a minimum force for holding the backup roll in engagement with the fuser roll structure. Solenoid means serves to actuate the linkage mechanism and also provides the means for maintaining roll engagement at a substantially reduced power requirement compared to the actuating power required.
