Abstract
A method for maintaining mailpiece integrity in a mailing system when a mechanical module experiences an error. For one category of errors, the mailing system may automatically recover from the error without operator intervention. For the remaining category of errors, the mailing system may recover from the error with minimum operator intervention, that is, the operator may be required to only remove the error producing mailpiece. A motion control processor for an error producing mechanical module will report a fault to its corresponding mailpiece builder task and the error detector task. Movement of at least the error producing mailpiece shall stop. The fault will be reported to the mailpiece builder tasks corresponding to the mechanical modules having no error condition. The mailing system shall suspend further processing of mailpieces upstream from the error producing mailpiece. For one category of errors, the mailing system will purge the error producing mailpiece from the error producing module without operator intervention. For the remaining category of errors, the operator will be required to remove at least the error producing mailpiece. State machines are then selected to …
