Abstract
A method and apparatus are disclosed for automatically calibrating media feed timing operations for both internal media handling and for media transfers between coupled feeder and receiving devices. Each of the devices is equipped with a microprocessor and a read-only memory (ROM) for program storage. A stop location is determined for the media feed path of each receiving device. In addition, the media path of each feeder device is equipped with a media detection sensor near its exit. The distance between this sensor and the media path exit of the feeder device may be determined by manual measurement. In addition, each feeder device must 'know' the speed at which it transports pages along the media path. Each feeder device is given the page stop specifications of any attached receiving devices over a communication bus at system boot-up. The feeder device will then use that information to set its page advancement motor timer to a value which will result in media pages being moved from the feeder device to the proper location in the receiving device.
