ABSTRACT:
A roller fuser including a driven roller and an idler roller which form a nip to fuse toner images to copy sheets. The idler roller is moved into and out of engagement with the driven roller by an expandable bladder which is inflated with a pressurized gaseous medium. A copy sheet detector is positioned very close to the nip exit of the rollers. In case of a copy sheet jam in the roller nip, the detector provides a jam detection signal which effects rapid exhaustion of gaseous medium from the bladder to disengage the rollers and prevent further driving of a copy sheet into the roller nip.
