Abstract
Described herein is a printing system including a plurality of print processing modules which can selectively transfer print media there between during printing. The system further including a controller that can predict the impending unhealthy state of at least one module and redirect one of an unprocessed job and a partially processed job preemptively from an impending unhealthy module to selectively one of a healthy module and another unhealthy module, with suitable characteristics, to process unprocessed portions of the job.
Claims22
A printing system, comprising
- a plurality of print processing modules which selectively transfer print media therebetween during printing;
- and
- a controller that predicts the impending unhealthy state of at least one module and redirects one of an unprocessed job and a partially processed job preemptively from an impending unhealthy module to selectively a healthy module and another unhealthy module, with suitable capabilities, to process unprocessed portions of the job.
The printing system of 1, wherein the job is redirected with human intervention, without human intervention, or a combination thereof.
A method for predicting the impending unhealthy state of one or more capabilities of a printing system having a plurality of modules, comprising:
- the one or more capabilities representing diminished capabilities relative to the capabilities available when a module is healthy;
- and,
- redirecting one of an unprocessed job and a partially processed job preemptively from an impending unhealthy module to selectively a healthy module and another unhealthy module, with suitable capabilities, to process unprocessed portions of the job.
A method for preemptively redirecting jobs in a printing system with multiple marking engines and multiple print media components, comprising:
- predicting an impending unhealthy state of a marking engine and redirecting jobs from the impending unhealthy marking engine to another marking engine;
- and,
- predicting the impending state includes tracking the rate of misfeeds and multifeeds and redirecting one of an unprocessed job and a partially processed job to selectively at least the another marking engine and from one print media component to another print media component.
