Abstract:
1. An imaging device comprising an imaging station, a sheet media tray spaced from said imaging station, a media guide path between said imaging station and said media tray, a pivotally mounted media feed system located for driving media through said media guide path, a pivotally mounted media sensor located for sensing media in said media guide path, said media sensor having an abutment surface, at least one motor to provide torque to said media feed system, a slip connection between said media feed system and said media sensor to provide torque to said media sensor, a blocking member located on said imaging device to block said media sensor to limit movement of said media sensor away from said media guide path, a rotatable member mounted on said imaging device having a ledge and an arm, and being resiliently biased to rotate said ledge to face said abutment surface of said media sensor for preventing pivoting of said media sensor, a lever being located to rotate said rotatable member by contact with said media feed system to move said ledge to not prevent pivoting of said media sensor when said media feed system pivots away from said media guide path a greater distance than said media sensor moves away from said media guide path, and wherein: said media feed system moves by said motor and said media sensor moves by said slip connection to bring said media sensor to said media for said media sensor to sense said media, said media feed system moves by said motor away from said media guide path and said media sensor moves away from said media guide path by said slip connection a limited, first amount at which said ledge faces said abutment surface in response to rotation under said bias of said rotatable member, said media feed system moves by said motor to said media guide path while said media sensor is held by said abutment and ledge and said slip connection slips, and said media feed system moves away from said media guide path in an amount greater than said first amount to contact said lever to thereby rotate said rotatable member and free said media sensor to move under said slip connection for sensing media in said media feed path.
