Abstract

A supply cartridge for containing a supply of imaging substance includes a cartridge body, and a light pipe attached to the cartridge body. The light pipe has a light output, and a light input for receiving light from an external light source.

Claims (36)

1. A supply cartridge for containing a supply of imaging substance, comprising:

a cartridge body; and

a light pipe attached to said cartridge body, said light pipe having:

a first light output

a second light output, and

a light input for receiving light from an external light source, wherein a position of said light pipe with respect to said cartridge body is dependent on a characteristic of said supply cartridge, and wherein said characteristic is one of a cartridge manufacturer or vendor, the light pipe further includes:

a first light pipe segment for collecting light received from said light input and directing said light in a first direction toward said first light output; and

a reflective surface positioned to intersect said light in said first direction and redirect a portion of said light in a second direction different from said first direction toward said second light output, wherein said second light output is an illumination device positioned on said cartridge body to receive said light in said second direction, said illumination device illuminating upon receiving said light in said second direction to provide a visual feedback indicating successful reception of said light in said first direction.

2. A supply cartridge for containing a supply of imaging substance comprising:

a cartridge body; and

a light pipe attached to said cartridge body, said light pipe having:

a first light output

a second light output, and

a light input for receiving light from an external light source, wherein said cartridge body has a side that defines a plane, and wherein said light pipe includes a straight-line light path that extends from said light input to said light output, said straight-line light path being disposed at an acute angle with respect to said plane, the light pipe further includes:

a first light pipe segment for collecting light received from said light input and directing said light in a first direction toward said first light output; and

a reflective surface positioned to intersect said light in said first direction and redirect a portion of said light in a second direction different from said first direction toward said second light output, wherein said second light output is an illumination device positioned on said cartridge body to receive said light in said second direction, said illumination device illuminating upon receiving said light in said second direction to provide a visual feedback indicating successful reception of said light in said first direction.

3. A supply cartridge for containing a supply of imaging substance, comprising:

a cartridge body;

a light pipe attached to said cartridge body, said light pipe having:

a first light output

a second light output, and

a light input for receiving light from an external light source, wherein said light pipe includes:

a first light pipe segment for collecting light received from said light input and directing said light in a first direction toward said first light output; and

a reflective surface positioned to intersect said light in said first direction and redirect portion of said light in a second direction different from said first direction toward said second light output, wherein said second light output is art illumination device positioned on said cartridge body to receive said light in said second direction, said illumination device illuminating upon receiving said light in said second direction to provide a visual feedback indicating successful reception of said light in said first direction.

4. The supply cartridge of claim 3 , wherein said illumination device is passive device that illuminates upon receiving said light in said second direction to provide said visual feedback on said supply cartridge indicating successful reception of said light in said first direction.

5. The supply cartridge of claim 4 , wherein said visual feedback is an indication of proper installation of said supply cartridge in an imaging apparatus.

6. A supply cartridge for containing a supply of imaging substance, comprising:

a cartridge body; and

a light pipe attached to said cartridge body, said light pipe having:

a first light output

a second light output, and

a light input for receiving light from an external light source, said light pipe being one of a pair of light pipes attached to said cartridge body, wherein the axis of said pair of light pipes are oriented to be substantially parallel, and said pair of light pipes carry light travelling in opposite directions, the light pipe further includes:

a first light pipe segment for collecting light received from said light input and directing said light in a first direction toward said first light output; and

a reflective surface positioned to intersect said light in said first direction and redirect a portion of said light in a second direction different from said first direction toward said second light output, wherein said second light output is an illumination device positioned on said cartridge body to receive said light in said second direction, said illumination device illuminating upon receiving said light in said second direction to provide a visual feedback indicating successful reception of said light in said first direction.

7. The supply cartridge of claim 6 , wherein said pair of light pipes is formed integral with said cartridge body.

8. The supply cartridge of claim 6 , wherein said pair of light pipes is connected to a component of said cartridge body.
