Abstract
An apparatus in which release material is applied to a heated fuser member. A back up member is in communication with the fuser member and a sheet of support material having particles thereon passes therebetween. The particles on the sheet of support material contact the fuser member. The apparatus reciprocates a bar of release material into and out of contact with the fuser member. The foregoing abstract is neither intended to define the invention disclosed in the specification, nor is it intended to be limiting as to the scope of the invention in any way.
Claims10
An apparatus for applying release material to a heated fuser member in communication with a back-up member wherein a sheet of support material having particles thereon passes therebetween with the particles contacting the fuser member, including:
- a frame;
- a bar of release material mounted movably in said frame;
- means for resiliently urging said bar to a first position spaced from the fuser member;
- a solenoid operatively associated with said bar;
- and
- means for periodically energizing said solenoid to move said bar from the first position spaced from the fuser member to a second position in contact with the fuser member, said resilient means returning said bar to the first position upon the energization of said solenoid.
A fusing apparatus employed in an electrostatographic printing machine for permanently affixing toner particles to a sheet of support material, including:
- a heated fuser roll;
- a back-up roll in communication with said fuser roll such that the sheet of support material passes therebetween with the toner particles contacting said fuser roll;
- a frame;
- a bar of release material mounted movably in said frame;
- means for resiliently urging said bar to a first position spaced from said fuser roll;
- a solenoid operatively associated with said bar;
- and
- means for periodically energizing said solenoid to move said bar from the first position spaced from said fuser roll to a second position in contact with said fuser roll, said resilient means returning said bar to the first position upon de-energization of said solenoid.
