Abstract

In one example in accordance with the present disclosure a print duplexing assembly is described. The assembly includes a duplexing device to facilitate printing on both sides of a print media. The assembly also includes a platen coupled to the duplexing device to guide the print media along a feed path as it is being printed on. The platen and the duplexing device are selectively removable from a printing device in which they are installed.

First claim

What is claimed is:

1. A print duplexing assembly comprising:
a duplexing device to facilitate printing on both sides of a print media; and
a platen coupled to the duplexing device, the platen to guide the print media as it is being printed on;
wherein the platen and the duplexing device are coupled so as to be selectively removable as a single unit from a printing device in which they are inserted.

2. The print duplexing assembly of claim 1 , further comprising an aerosol filter disposed within the duplexing device to catch aerosolized fluid droplets ejected from a print bar.

3. The print duplexing assembly of claim 1 , further comprising a non-volatile memory device disposed on the duplexing device to store information.

4. The print duplexing assembly of claim 1 , wherein the platen and the duplexing device unit comprises retention devices to interact with rails of the printing device in which they are inserted so that the duplexing device and platen are slidable along the rails into and out of the printing device.

5. The print duplexing assembly of claim 4 , wherein the retention devices allow the print duplex assembly to pivot about ends of the rails and comprise a spring-loaded latch for releasing the print duplex assembly from the rails.

6. The print duplexing assembly of claim 1 , wherein the platen is mounted to the duplexing device using with springs so that the platen moves independently from the duplexing device while inserted in the printing device.

7. The print duplexing assembly of claim 6 , wherein the springs bias the platen against a feed shaft of a printing device, the platen further comprising bearings to align the platen with the feed shaft.

8. The print duplexing assembly of claim 1 , further comprising a number of retention devices to:
allow the print duplexing assembly to be slid out from an interior of the printing device, and retained to the printing device; and
to interface with a latch on the printing device to facilitate removal of the print duplexing assembly.

9. The print duplexing assembly of claim 1 , further comprising fasteners to couple the platen to the duplexing device.

10. A print duplexing assembly comprising:
a service fluid container comprising a bucket and a lid joined together so that the lid covers and seals the bucket to prevent fluid from spilling out of the service fluid container, wherein the service fluid container comprises openings arranged to catch excess fluid ejected from a print bar; and
a duplexing device to facilitate printing on both sides of a print media;
wherein:
the service fluid container is disposed on an interior of the duplexing device; and
the duplexing device and corresponding service fluid container are selectively removable together as a single unit from a printing device in which they are inserted.

11. The print duplexing assembly of claim 10 , wherein the service fluid container comprises:
an aerosol filter to catch aerosolized fluid droplets of printing fluid; and
a number of fluid absorption devices to absorb excess printing fluid.

12. The print duplexing assembly of claim 11 , further comprising a non-volatile memory device disposed on the duplexing device to store information.

13. The print duplexing assembly of claim 10 , further comprising:
a platen joined to the duplexing device, wherein the platen and duplexing device are modular to the printing device in which they are installed.

14. The print duplexing assembly of claim 10 , wherein the bucket of the service fluid container is glued to the lid of the service fluid container.

15. The print duplexing assembly of claim 10 , wherein the bucket and lid are sealed together with a water-tight seal.

16. The print duplexing assembly of claim 10 , wherein the openings extend through the platen to allow fluid ejected from the print bar to move through the platen and into the service fluid container.

17. A print duplexing assembly comprising:
a duplexing device to facilitate printing on both sides of a print media; and
a non-volatile memory device disposed on the duplexing device to store information;
wherein the duplexing device is selectively removable from a printing device in which it is inserted.

18. The print duplexing assembly of claim 17 , further comprising a platen joined to the duplexing device, wherein the platen and duplexing device are modular to the printing device in which they are installed.

19. The print duplexing assembly of claim 17 , wherein the non-volatile memory stores an indication of an amount of fluid stored inside the print duplexing assembly.

20. The print duplexing assembly of claim 17 , wherein the non-volatile memory device is an electrically erasable programmable read-only memory (EEPROM) device.
