ABSTRACT:
In a printing system in which the print media sheets are alternately fed from the same stack in the same tray by two sheet feeders at opposite sides into different sheet paths, at least one of the sheet feeders is repositionable towards and away from the other for feeding different size sheets, and the connecting sheet path is repositionable with the repositioning of the sheet feeder. The repositioning of the sheet feeder and its associated sheet path may be automatic in coordination with the normal resetting of a tray stack edge guide with the loading of different size sheets into the tray. The enhanced rate sheet feeding may be for a dual print engine printing system and/or selectably common or reversed sheet facing. Alternating coordinated lifting of a nudger roll of one sheet feeder with operation of the opposing sheet feeder, and retard nips spaced from the stack, may be provided.
