Abstract
A turret fusing apparatus including (a) a frame; (b) a rotatable external pressure roller mounted at a first mounting position to the frame; and (c) a rotatable turret assembly mounted at a second mounting position on the frame for selectably forming different fusing nips having different characteristics with the rotatable external pressure roller. The rotatable turret assembly has at least a pair of internal pressure rollers including a first rotatable internal pressure roller for forming a first fusing nip having a first set of characteristics with the rotatable external pressure roller, and a second rotatable internal pressure roller for forming a second fusing nip having a second set of characteristics with the rotatable external pressure roller.
Claims17
A turret fusing apparatus comprising:
- (a) a frame;
- (b) a rotatable external pressure roller mounted at a first mounting position to said frame;
- and
- (c) a rotatable turret assembly mounted at a second mounting position on said frame for selectably forming different fusing nips having different characteristics with said rotatable external pressure roller, said rotatable turret assembly having at least a pair of internal pressure rollers including a first rotatable internal pressure roller for forming a first fusing nip having a first set of characteristics with said rotatable external pressure roller, and a second rotatable internal pressure roller for forming a second fusing nip having a second set of characteristics with said rotatable external pressure roller, and a movable endless fusing belt mounted over said at least a pair of internal pressure rollers.
A turret fusing apparatus comprising:
- (a) a frame;
- (b) a rotatable external pressure roller mounted at a first mounting position to said frame;
- (c) a rotatable turret assembly mounted at a second mounting position on said frame for selectably forming different fusing nips having different characteristics with said rotatable external pressure roller, said rotatable turret assembly having at least a pair of internal pressure rollers including a first rotatable internal pressure roller for forming a first fusing nip with said rotatable external pressure roller, and a second rotatable internal pressure roller for forming a second fusing nip with said rotatable external pressure roller, and a movable endless fusing belt mounted over said at least a pair of internal pressure rollers;
- (d) moving means connected to said rotatable turret assembly for moving said rotatable turret assembly;
- and
- (e) a programmable controller coupled to said moving means for controllably moving and positioning one of said first rotatable internal pressure roller and said second rotatable internal pressure roller in nip forming relation with said rotatable external pressure roller.
An electrostatographic reproduction machine comprising:
- (a) a moveable imaging member including an imaging surface;
- (b) imaging means for forming and transferring a toner image onto a toner image carrying sheet;
- and
- (c) a turret fusing apparatus including
- (i) a frame;
- (ii) a rotatable external pressure roller mounted at a first mounting position to said frame;
- and
- (iii) a rotatable turret assembly mounted at a second mounting position on said frame for selectably forming different fusing nips having different characteristics with said rotatable external pressure roller, said rotatable turret assembly having at least a pair of internal pressure rollers including a first rotatable internal pressure roller for forming a first fusing nip having a first set of characteristics with said rotatable external pressure roller, and a second rotatable internal pressure roller for forming a second fusing nip having a second set of characteristics with said rotatable external pressure roller, and a movable endless fusing belt mounted over said at least a pair of internal pressure rollers.
