Abstract:
1. A productivity module for increasing duplex throughput of a first print engine, comprising: a second print engine; a controller 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; and an inverter comprising: wherein a first path comprises a receiver sheet travel path through the input paper path, the inversion paper path, and the output paper path when the diverter is in an inversion position; a second path comprises a receiver sheet travel path through the input paper path and the output paper path when the diverter is in a non-inversion position; and the controller is further configured to adjust a difference of a travel time of a receiver sheet in the first path as compared to a travel time of a receiver sheet in the second path to be an integral multiple of a period between the receiver sheets.
