Abstract

A printer includes a print engine to print on print media within a print zone, a print media path including a print path portion to direct the print media through the print zone in a first direction, a duplex media path including a duplexing path portion to redirect the print media to the print media path in a second direction opposite the first direction, and a first tandem media tray to hold a first quantity of the print media and a second tandem media tray positioned laterally of the first tandem media tray to hold a second quantity of the print media, wherein the duplexing path portion extends a combined width of the first tandem media tray and the second tandem media tray.

First claim

1 . A printer, comprising:
a print engine to print on print media within a print zone; a print media path including a print path portion to direct the print media through the print zone in a first direction; a duplex media path including a duplexing path portion to redirect the print media to the print media path in a second direction opposite the first direction; and a first tandem media tray to hold a first quantity of the print media and a second tandem media tray positioned laterally of the first tandem media tray to hold a second quantity of the print media, wherein the duplexing path portion extends a combined width of the first tandem media tray and the second tandem media tray.

2 . The printer of claim 1 , wherein the print media path includes an output path portion to direct the print media toward an output, including in a third direction substantially perpendicular to the first direction, wherein the output path portion provides a reversing path portion of the duplex media path.

3 . The printer of claim 1 , further comprising:
a bypass media path to receive print media from externally of the printer and direct the print media to the print media path via the duplexing path portion of the duplex media path.

4 . The printer of claim 3 , wherein the print media path includes a converging path portion to receive print media from the bypass media path, the duplex media path, a tandem tray media path communicated with at least one of the first tandem media tray and the second tandem media tray, and an auxiliary media path communicated with at least one auxiliary media tray.

5 . The printer of claim 1 , wherein the duplexing path portion is to receive print media from one of the first tandem media tray and the second tandem media tray at an intermediate portion thereof and direct the print media to the print media path.

6 . The printer of claim 1 , further comprising:
at least one service module to service the print engine, the at least one service module positioned one of laterally and vertically of the print engine, and positioned vertically of at least one of the first tandem media tray and the second tandem media tray.

7 . A printer, comprising:
a print engine to print on print media within a print zone; a tandem media tray set including a first tandem media tray to hold a first quantity of the print media and a second tandem media tray positioned laterally of the first tandem media tray to hold a second quantity of the print media; a service module to service the print engine, the service module positioned laterally of the print engine and vertically of one of the first tandem media tray and the second tandem media tray; and another service module to service the print engine, the another service module positioned vertically of the print engine and vertically of the other of the first tandem media tray and the second tandem media tray.

8 . The printer of claim 7 , further comprising:
a print media path including a print path portion to direct the print media through the print zone in a first direction; and a duplex media path including a duplexing path portion to redirect the print media to the print media path in a second direction opposite the first direction.

9 . The printer of claim 8 , wherein the duplexing path portion extends a width of the tandem media tray set.

10 . The printer of claim 8 , wherein the print media path includes a converging path portion to receive print media from the duplex media path, a tandem tray media path communicated with the tandem media tray set, an auxiliary media path communicated with at least one auxiliary media tray, and a bypass media path communicated with a bypass media tray communicated externally of the printer.

11 . The printer of claim 8 , further comprising:
a tandem tray media path portion to receive print media from at least one of the first tandem media tray and the second tandem media tray and direct the print media to an intermediate portion of the duplexing path portion for direction to the print media path via the duplex media path.

12 . A method of operating a printer, comprising:
receiving print media from one of a first tandem media tray and a second tandem media tray positioned laterally of the first tandem media tray; directing the print media through a print zone in a first direction; and receiving the print media from the print zone and redirecting the print media to the print zone, including directing the print media in a second direction opposite the first direction along a duplexing path portion extended a combined width of the first tandem media tray and the second tandem media tray.

13 . The method of claim 12 , further comprising:
receiving print media from a bypass media tray communicated externally of the printer and directing the print media from the bypass media tray in the second direction along a bypass path portion to the duplexing path portion and to the print zone via the duplexing path portion.

14 . The method of claim 12 , wherein receiving print media from one of the first tandem media tray and the second tandem media tray includes directing the print media to an intermediate portion of the duplexing path portion and to the print zone via the duplexing path portion.

15 . The method of claim 12 , wherein the print media is to be printed on by a print engine, and further comprising:
servicing the print engine with at least one of a service module to be positioned laterally of the print engine and vertically of one of the first tandem media tray and the second tandem media tray during non-servicing of the print engine and a service module positioned vertically of the print engine and vertically of the other of the first tandem media tray and the second tandem media tray.
