ABSTRACT:
Receiving sheet jams in a toner image fuser are cleared by raising an upper frame of an image-forming apparatus. A pressure roller in the fuser is fixed to the upper frame and separates from a fusing roller when the upper frame is raised. Inner and outer guides providing a slot for the receiving sheet leading away from the fuser to an output hopper are mounted to separate when the upper frame is raised, permitting clearance of paper stuck between the guides. The outer guide is prevented from following the inner guide as the upper frame is raised, but instead stops at a position covering the fusing roller to prevent touching of a hot fusing roller by the operator while the operator is clearing a jam.
