Xerographic roll fuser.

摘要

Fuser rolls (31, 32) are moved into and out of engagement by means of a biassed linkage system (38, 37, 39). This linkage system normally causes opening of the rolls. A cam follower arm is coupled to the linkage system by means of a solenoid. The rolls are closed only when the follower arm is following the high portion of a rotatable cam (33) and also the solenoid is energised.
