Abstract

An imaging device, including one or more imaging units for use in transferring toner to media sheets, one of the imaging units being a black imaging unit for transferring black toner; a media transport path having a duplex path, the duplex path having at least one set of rollers for independently moving media sheets through the duplex path; and a controller operatively coupled to the one or more imaging units and the media transport path, for staging one or more media sheets in the duplex path for a period of time. The period of time results in an increase in the interpage gap which may be utilized while the imaging device interrupts a printing operation to perform any of a number of operations.
