Abstract
A method and related apparatus for inverting receivers in a plurality of physically coupled print engines by using an inverter such that one or more images are digitally printed on designated receiver sheets whereby all receiver sheets that can be inverted are inverted and those that cannot be inverted are not inverted. A skip frame is added to the first print engine preceding each noninvertible receiver sheets.
Claims20
A method for printing and inverting sheets in a plurality of physically coupled print engines such that a one or more designated receivers are capable of being inverted, the method comprising:
- a. printing a first image on a first surface of one or more receivers using a first print engine;
- b. feeding a first designated receiver of one or more designated receivers into an inverter that is functionally coupled to the first print engine to invert the first designated receiver;
- c. feeding the first designated receiver from the inverter into a second print engine that is functionally coupled to the inverter;
- and
- d. repeating the above steps for each of the one or more designated receivers so that any non-designated receivers-are not inverted.
An electrophotographic printer for printing and inverting sheets in a plurality of physically coupled print engines such that a one or more designated receivers are capable of being inverted, the apparatus comprising:
- a plurality of coupled electrophotographic engines for printing a first image on a first surface of one or more receivers using a first print engine;
- an inverter functionally coupled to the first print engine to invert the first designated receiver for inverting one or more designated receivers;
- a feeder for feeding a first designated receiver of the one or more designated receivers into the inverter and from the inverter into a second print engine that is also functionally coupled to the inverter;
- and
- a controller for inserting a skip frame ahead of a non-designated non-inverted sheet.
