Abstract: A method of diagnosing a printer problem includes correlating a wide range of printer data types with suggested solutions. Printer diagnostic data, which may include usage information and printer status information collected over a period of time, is parsed into individual components. The components are then input into a set of rules. Each rule compares each component with a corresponding reference value to generate a comparison result, correlates the comparison result with a set of actions including solutions, and if there is a correlation between the comparison result and a solution, providing the solution.

Abstract: A method of diagnosing a printer includes performing a series of parametric tests on the printer at the time of manufacture to generate a set of baseline values for the printer and storing the baseline results. The baseline results may be stored remotely or with the printer, or both. A set of maximum parametric test variations for the printer type is generated, such that each maximum parametric test variation is associated with a particular printer fault event. At the time of a suspected printer fault, the same parametric tests are performed and a set of suspected fault values generated. The difference between the suspected fault value and the baseline value is calculated for each parametric test. If the difference for a particular parametric test is greater than the maximum parametric test variation for that particular parametric test, the print fault event associated with the parametric test value may be indicated.
