Mutualistic engine controller |
摘要 |
A printing device has a printing engine that is at least partially made up of a customer replaceable unit or units. An engine controller is operatively connected to the printing engine. The engine controller uses software to control the operations of the printing engine. A non-volatile memory is operatively connected to the engine controller. The non-volatile memory stores values used by the engine controller to control operations of the printing engine. An adapter card is operatively connected to the non-volatile memory and to the customer replaceable units. The customer replaceable unit has a memory unit and the adapter card reads data from the memory unit. The adapter card uses the data to directly alter values within the non-volatile memory by bypassing the engine controller when communicating with the non-volatile memory. Further, the adapter card alters the non-volatile memory without altering the software used by the engine controller. |
