Abstract
Apparatus in a copier fusing assembly for distributing the wear on a hot roll occasioned by the use of variable length copy sheets. This wear is distributed over the horizontal length of the hot roll by reversing the hot roll, end-for-end. Easy reversal of the hot roll is made possible by utilization of a hot roll subframe which is removably mounted in the copier fuser mainframe. A handle on the subframe allows for manual removal of the subframe and hot roll from the mainframe and out of the copier where they are reversed and inserted back into the mainframe.
