Ambient condition sensor for a photosensitive media cartridge

A photosensitive media cartridge comprising:

• a housing adapted to hold a stack of photosensitive media;
• and
• an ambient condition sensor positioned within said housing for sensing ambient conditions around photosensitive media in said housing and providing an ambient condition signal indicative thereof, such that a development of the photosensitive media is based on the sensed ambient conditions;
• said ambient condition sensor comprising a top layer, a humidity responsive layer, a conductive layer and a base support layer, wherein a rate of response to ambient conditions of at least one of said transparent top layer, said humidity responsive layer, and said base support layer matches a rate of response to ambient conditions of the photosensitive media in said housing.

An image-forming arrangement comprising:

• an image-forming device for forming a latent image on a photosensitive media;
• and
• a media cartridge for holding a stack of photosensitive media therein, said media cartridge being adapted to be inserted into said image-forming device to permit a conveyance of the photosensitive media to the image-forming device, said media cartridge comprising an ambient condition sensor for sensing ambient conditions around media in said cartridge, such that a development of the photosensitive media in said image-forming device is based on the sensed ambient conditions;
• said ambient condition sensor comprising a transparent top layer, a humidity responsive layer, a conductive layer and a base support layer, wherein a rate of response to ambient conditions of at least one of said transparent top layer, said humidity responsive layer, and said base support layer matches a rate of response to ambient conditions of the photosensitive media in the media cartridge.

A method of controlling image development comprising:

• providing an ambient condition sensor in a cartridge which holds photosensitive media therein, said ambient condition sensor sensing ambient conditions around photosensitive media in the cartridge, said ambient condition sensor comprising at least a cover layer and a conductive layer, wherein a rate of response to ambient conditions of at least said cover layer matches a rate of response to ambient conditions of the photosensitive media in the media cartridge;
• inserting the cartridge to an insertion position in a printer which permits a passage of photosensitive media from the cartridge to the printer;
• sensing ambient conditions around the photosensitive media by way of the ambient conditions sensor;
• and
• controlling a development of images on the photosensitive media based on the sensed ambient conditions.
