Abstract
A photoprocessing apparatus for sensing type of photoprocessing consumable and method of assembling the apparatus. The invention includes a photographic printing and developing apparatus (10) adapted to allow the apparatus to sense types of supplied consumable photosensitive paper and photoprocessing chemicals and method for assembling the consumable paper and chemicals for sensing. An electrically programmable read/write memory contained in a transponder (54) is integrally attached to the consumable paper or chemicals package. The transponder (54) is capable of receiving a first, RF frequency electromagnetic field and deriving power and address information from the first frequency, then generating a second RF frequency electromagnetic field in response, where the second electromagnetic field is characteristic of the data stored in memory. A transceiver (50) is disposed within the photographic printing and developing apparatus (10) with antenna (56) and support components for polling each transponder (54). As instructed by a control logic processor (14), transceiver (50) can both read manufacturing data from the transponder (54) about the consumable paper or chemical and write usag…
