Patent ID: 8473249

Claim:
A system for identifying a printing device having an exceptional incident rate among a plurality of printing devices, the system comprising: a processor; and a processor-readable storage medium in communication with the processor, wherein the processor-readable storage medium contains one or more programming instructions that, when executed, cause the processor to: receive, for each of a plurality of printing devices, a printing device model, a print volume, and an incident count associated with the printing device, wherein the incident count comprises a number of incidents occurring within a particular time frame, and wherein at least one of the incidents comprises one of a paper jam, a device malfunction, and a software error, determine a generalized linear regression model of the incident counts for each printing device model, for each printing device model, determine a predicted incident count using the generalized linear regression model, for each printing device, determine a residual value between the incident count for the printing device and the predicted incident count for the printing device model associated with the printing device, and identify one or more printing devices having a residual value exceeding a threshold value.
