Abstract
A media sheet inverter apparatus and method is disclosed. The media sheet inverter, according to one embodiment of the disclosure, comprises an input nip configured to receive a media sheet and a reversing roll nip configured to receive a media sheet from the input nip. The media sheet is subsequently held within the inverter for a predetermined time before being ejected to an output nip configured to receive the media sheet from the reversing roll nip. The inverter apparatus and method is especially suited to inverting alternating media sheets.
Claims25
A media sheet inverter apparatus comprising:
- an input nip configured to receive a media sheet;
- a reversing roll nip configured to receive a media sheet form the input nip, hold a media sheet for a predetermined time, and eject a media sheet;
- and
- an output nip operatively connected to the input nip, the output nip configured to receive a media sheet from the reversing roll nip and eject a media sheet,
- wherein the reversing nip holds a first media sheet while simultaneously a second media sheet is delivered to the output nip from the input nip.
A method of operating a media sheet inverter comprising:
- receiving a first media sheet at an inverter input;
- inverting the first media sheet and holding the first sheet within the inverter for a predetermined time, while allowing a second media sheet to proceed from the inverter input to an inverter output without being inverted;
- and
- ejecting the first media sheet at the inverter output, the first media sheet ejected from the inverter output subsequent to the second media sheet being ejected from the inverter output.
A printing apparatus comprising:
- a first printing module comprising:
- a media sheet input configured to receive a media sheet for marking;
- an image marking zone configured to mark a media sheet, the image marking zone operatively connected to the media sheet input;
- and
- an output inverter operatively connected to the image marking zone, the output inverter configured to invert a first media sheet while allowing a second media sheet to proceed from the inverter input to an inverter output without being inverted, and eject the first media sheet from the inverter output subsequent to the second media sheet being ejected from the inverter output.
A xerographic image system comprising:
- a first printing module comprising:
- an image marking zone configured to mark a media sheet;
- a media sheet input configured to receive a media sheet for marking, the media sheet input operatively connected to the image marking zone;
- and
- an output inverter operatively connected to the image marking zone, the output inverter configured to invert alternating media sheets, wherein the output inverter inverts a first media sheet while allowing a second media sheet to proceed from an inverter input to an inverter output without being inverted, and ejects the first media sheet from the inverter output subsequent to the second media sheet being ejected from the inverter output.
