PRINT ENGINE PRODUCTIVITY MODULE INVERTER

摘要

A productivity module for increasing duplex throughput of a first print engine is disclosed. The productivity module has a second print engine, a controller, and an inverter. The controller is configured to receive one or more timing signals from the first print engine and synchronize timing of the second print engine with the first print engine based at least in part on the timing signals received from the first print engine. The inverter has an input paper path having an entrance configured to accept one or more receiver sheets from the first print engine; an output paper path having an exit configured to supply the one or more receiver sheets to the second print engine; and an inversion paper path having an entrance coupled to an exit of the input paper path and an exit coupled to an entrance of the output paper path.
