Abstract
Roll fuser apparatus for fixing toner images to copy sheets by the application of heat and pressure. The apparatus is characterized by the provision of a backup roll which can be quickly removed from the apparatus with a minimum of handling. To this end the backup roll is supported in the apparatus by a pair of frame members which are bolted to a backup roll support member which forms an integral part of the apparatus. A pair of hook-like members support the backup roll after the bolts have been removed; therefore, the backup roll need not be handled prior to the removal of the bolts and then it can be simply lifted out of the apparatus. Replacement is likewise simple.
Claims13
A roll fuser assembly for use in a copier apparatus for fixing toner images to sheets of copy paper, said assembly comprising:
- a heated fuser roll structure;
- means for supporting said fuser roll structure for rotational movement in said fuser assembly;
- a backup roll;
- means for securing said backup roll above said fuser roll structure whereby said roll and roll structure form a nip therebetween through which sheets of copy paper having toner images thereon pass with the toner images contacting said heated fuser roll structure;
- and
- means for supporting said backup roll above said fuser roll structure with said securing means removed to thereby render it unnecessary to handle said backup roll prior to removal of said securing means.
