<p>A modular device (10), such as an electrophotographic imaging machine, comprises an operation event log (30,32,34,36) in respective modules (20,22,24,26) of the device (10) to record time-stamped events, e.g., errors, and a configuration log (16) in a central controller (12) to keep track of changing configurations due to swapping or removal of modules. A controller (12) updates the configuration log (16) each time a module is added to or removed from the device (10). Log information may be stored locally with the device (10) or in a remote server accessible via a network to facilitate remote diagnostics. To assist in diagnostics, the disclosed method includes merging (106) the configuration and events logs in a way to display (110) log entries according to a selected configuration where errors in current modules are demarcated. The apparatus includes routines in the controller to effect retrieval, processing, and display of demarcated events according to a selected configuration. <IMAGE></p> |
