ABSTRACT:
The present invention relates to utilizing memory provided in a machine replaceable sub-assembly to be a medium of distribution for software code updates to that machine relating as to how that machine should operate. In one alternative, there is provided a method for operating a machine employing the steps of providing a replaceable sub-assembly separable from the machine, the replaceable sub-assembly further comprising a wireless interface and a memory in which is stored software code of executable instructions. The method further provides communicating via the wireless interface with the replaceable sub-assembly to store software code of executable instructions relating to the operation of the machine into the memory. The method then provides placing the replaceable sub-assembly into the machine, reading the memory, placing the stored software code of executable instructions into the machine as new machine software code, and then operating the machine in accordance with the new software code. In this way, the replaceable sub-assembly becomes the medium for the machine's software updates.
