Disclosed is a built-in data collection device incorporated into electrophotographic printing machines for recording information about drops, shock, vibrations, temperature and humidity experienced in the distribution process. As shown in the accompanying figure, data collection device 10 comprises a printed circuit board 12 having sensors 14 and 16 mounted thereon. Sensor 14 senses shock on a tri-axis basis while sensor 16 senses temperature and humidity. Data sensed by sensors 14 and 16 is collected in analog format and converted to digital format by Analog-to-Digital (AD) circuitry not shown. Port 18 allows for connection to a local computer without having to remove the machine covers. A lithium battery 20 powers device 10 so that data collection occurs during machine shipment.
