Abstract
A fuser assembly includes a heated member and backup member forming a fusing nip. A nip loading spring biases into contact the backup member and the heated member. A bellcrank contacts the nip loading spring such that upon opening of an access door of the imaging device, the bellcrank acts on the nip loading spring to reduce a force between the backup member and the heated member but keeping in contact the backup member and the heated member. The bellcrank typifies a wire or other flexible lever. A cam pivots as the access door opens and engages the wire to compress the nip loading spring during use.
