Abstract
A modular fuser assembly having a lightweight plastic structural housing. The lightweight housing is made possible by utilizing heavy steel endplates which are designed so that the net moment on each end plate pair is minimized. This is accomplished by having the load points on opposite sides of the endplate and aligned such that the moments tend to negate each other. The design of the endplates allows the use of relatively lightweight cross members thus enabling the lightweight thermoplastic housing.
Claims4
A modular fuser assembly comprising:
- a cylindrical fusing member;
- a cylindrical pressure member in contact with said cylindrical fusing member to form a nip therebetween;
- a pair of plate members located at each end of said cylindrical fuser member and said cylindrical pressure member to maintain a spatial relation therebetween while aligning load forces to cancel torsional moments on said plate members;
- and
- a thermoplastic housing supporting said plate members and said fusing member and said pressure member.
