Abstract
A method of diagnosing a printer's status using an encoded image printed and/or displayed by the printer. The printer can produce an encoded image, such as a barcode, that indicates status values in one or more categories. A client device with a camera, such as a smartphone, can take a picture of the encoded image and transmit it to a printer status server. The printer status server can analyze the status values encoded in the encoded image to diagnose problems with the printer, and can return applicable user instructions indicating how to fix and/or prevent the problems.
Claims21
A method of diagnosing a printer's status, comprising:
- periodically producing encoded images at a printer based on an automated schedule, each encoded image comprising encoded representations of status values in one or more status categories that describe the printer's current status;
- receiving a digital picture comprising one of the encoded images at a printer status server from a client device over a network connection, thereby providing a received encoded image, wherein a network address of the printer status server is indicated on indicia attached to the printer and the client device obtains the network address for the printer status server responsive to an image of the indicia;
- decoding the received encoded image at the printer status server to obtain current status values;
- updating a printer status database configured to track historical data about the printer with the current status values from the received encoded image;
- analyzing the current status values and comparing the current status values to historical data, thereby determining whether a problem exists at the printer;
- retrieving, upon determining that the problem exists, a user instruction from the printer status database that describes corrective actions that can be taken to fix and/or prevent the problem;
- and,
- electronically sending the user instructions from the printer status server to a designated destination, wherein the network address of the designated destination is associated with the network address of the printer status server.

A method of diagnosing a printer's status, comprising:
- generating a computer-readable status report, periodically according to an automated schedule, with a printer that comprises status values in one or more status categories that describe the printer's current status, and submitting the computer-readable status report from the printer to a printer status server when a data connection is available between the printer and the printer status server;
- and,
- generating an encoded image at the printer when the data connection between the printer and the printer status server is unavailable, the encoded image comprising encoded representations of the status values, and producing the encoded image with the printer such that a digital picture of the encoded image can be taken with a digital camera at a client device and the client device can transmit the digital picture to the printer status server;
- wherein the printer status server is configured to diagnose current and/or future problems with the printer based on the status values in the computer-readable status report and the encoded image, and to retrieve one or more user instructions describing corrective actions for fixing and/or preventing the problems;
- and,
- wherein a network address of the printer status server is indicated on indicia attached to the printer and the client device obtains the network address for the printer status server responsive to an image of the indicia.
