ABSTRACT:
An image forming device includes a body and one or more door assemblies. At least one door assembly may be movable between open and closed orientations. A variety of mechanical and electrical interlocks may be used to control motion of the door assemblies. A first interlock may prevent a door assembly from moving under the influence of a force between an open and closed orientation prior to a condition being satisfied. This condition may depend on the position of a second door assembly. A breakaway feature may release the first interlock when the closing force exceeds a predetermined level. A second interlock may work with the first interlock to keep a second door assembly from opening if the first door assembly is closed. An electrical interlock may disconnect power to the image forming device when the first door assembly is open.
