Error code history collection with quick response codes

A machine comprising:

• a display configured to present a first graphical image of a first quick response code, and a second graphical image of a second quick response code;
• and
• a controller in electronic communication with the display, and configured to:
• perform a background test in the machine to detect a fault caused by one or more errors in the machine;
• initiate a dispatch request through an operator associated with the machine to a service location in response to the fault, wherein the service location is distant from the machine, and the machine is characterized by a lack of a connection to a communication network to transfer data to and from the service location;
• generate the first quick response code in response to a first input signal received from a technician answering the dispatch request, wherein the first quick response code encodes first data, and the first data includes a plurality of first configuration items that describe the machine and one or more first error codes that characterize the one or more errors that were detected;
• transfer the first data in the first quick response code through the display to a mobile device brought to the machine by the technician, wherein the mobile device transfers the first data to the service location, the service location generates one or more recommended actions to repair the machine based on the first data and historical repairs of the machine, and the service location transfers the one or more recommended actions to the mobile device;
• perform a self-test in response to a second input signal received from the technician after a repair of the machine is completed by the technician based on the one or more recommendations generated at the service location;
• generate the second quick response code after the self-test has been completed, wherein the second quick response code encodes second data, and the second data includes a plurality of second configuration items that describe the machine and one or more second error codes that are valid after the repair;
• store the first data prior to the repair;
• and
• regenerate the first quick response code after the repair is completed, wherein the display is further configured to redisplay the first graphical image of the first quick response code after the repair is completed.

A method for collecting error code history comprising:

• performing a background test in a machine to detect a fault caused by one or more errors in the machine;
• initiating a dispatch request from the machine through an operator associated with the machine to a service location in response to the fault, wherein the service location is distant from the machine, and the machine is characterized by a lack of a connection to a communication network to transfer data to and from the service location;
• generating a first quick response code in response to a first input signal received by the machine from a technician answering the dispatch request, wherein the first quick response code encodes first data, and the first data includes a plurality of first configuration items that describe the machine and one or more first error codes that characterize the one or more errors that were detected;
• presenting a first graphical image of the first quick response code on a display of the machine;
• receiving the first graphical image of the first quick response code from the display at a mobile device brought to the machine by the technician;
• parsing the first data in the first quick response code into a format readable and understandable by the technician, wherein the format includes the plurality of first configuration items that describe the machine and the one or more first error codes;
• storing the first data in the mobile device;
• repairing the machine in response to the first data;
• performing a self-test in the machine in response to a second input signal from the technician after the repairing is completed by the technician;
• generating a second quick response code after the self-test has been completed, wherein the second quick response code encodes second data, and the second data includes a plurality of second configuration items that describe the machine and one or more second error codes that are valid after the repairing;
• presenting a second graphical image of the second quick response code on the display;
• receiving the second graphical image of the second quick response code from the display at the mobile device;
• storing the second data in the mobile device;
• transferring the first data and the second data from the mobile device to a computer at the service location;
• generating one or more recommended actions in the computer to repair the machine based on the first data, the second data, and historical repairs of the machine;
• and
• transferring the one or more recommended actions from the computer to the mobile device.
