Abstract:
1. A method for diagnosing a modular printing system having two or more interchangeable modules, the method comprising: a) determining a fault associated with the printing system has occurred; b) a controller identifying a first potentially failed module causing the fault; c) the controller identifying a first normally operating module interchangeable with the potentially failed module; d) the controller generating instructions to swap the first potentially failed module with the first normally operating module; e) executing the instructions; and f) determining if the fault has been corrected subsequent to executing the instructions to swap the first potentially failed module with the first normally operating module, wherein step f) comprises: executing a print job to determine if the fault has been corrected subsequent to executing the instructions to swap the first potentially failed module with the first normally operating module, and the controller generating instructions for a user to examine the output of the print job to determine if the fault has been corrected subsequent to executing the instructions to swap the first potentially failed module with the first normally operating module.
