Abstract
A method and apparatus provide for recovering from faults in an electronic reprographic system for scanning and synchronously or asynchronously processing and printing a plurality of jobs. The system is monitored for the occurrence of faults in a job, the faults are identified and recorded through a fault logging service and a specific response is initiated to the faults recorded by the fault logging service. Provision is made for using the log offline to determine the cause and effect of problems created by the faults in the system. The invention further provides for using the log online to monitor the occurrence of hardware faults in the system, and initiate the appropriate online diagnostic routine, whose response can further isolate a suspected problem.
