Jam-door open sensing using media sensor and method for use thereof

A multi-function peripheral device, comprising:

• an input paper tray;
• a feed path extending from said input tray to an output tray and defined by a feed path inner guide and a feed path outer guide;
• a jam-door pivotally mounted to a peripheral housing of said peripheral device to move between an open position and a closed position with respect to said feed path inner guide with said jam-door having said feed path outer guide extending therefrom;
• a sensor pivotally mounted for movement into and out of said feed path;
• a reflective surface opposite said sensor and in optical communication with said media sensor;
• and
• a controller with said media sensor in electrical communication with said controller, said controller inhibiting imaging operation of said peripheral device when said media sensor senses the jam-door in the open position based upon at least one signal received from the sensor.

In a printing device having a sensor positioned proximate a C-shaped feed path formed by an inner guide and an outer guide with said outer guide being formed on the inner surface of a jam-door pivotally mounted on said printing device and movable between an open position and a closed position with respect to the feed path, a method of detecting a state of the printing device, comprising:

• emitting a light from said media sensor directed at one of said inner guide and said outer guide;
• detecting a first light intensity when said sensor is on;
• and
• determining whether said jam-door is in one of the open position and the closed position by determining whether the detected first light intensity is within a preselected intensity range, and detecting a second light intensity without emitting a light from said sensor.

In a multi-function peripheral device having a sensor positioned proximate a feed path formed by an inner guide and an outer guide, said outer guide being formed on the inner surface of a jam-door pivotally mounted on said printing device and movable between an open position and a closed position with respect to the feed path, and a pick motor rotatably connected to said media sensor, a method of detecting a state of the peripheral device, comprising:

• powering on said peripheral device;
• rotating said pick motor in at least one direction;
• moving said sensor toward one of said inner guide and said outer guide with said rotation;
• emitting a light from said sensor at one of said inner guide and said outer guide;
• detecting a light intensity;
• and
• determining whether said detected light intensity is within a preselected intensity range indicating said jam-door is in the closed position.
