Abstract

A printer including a print bar and a dryer system. The print bar operates to deposit printing material in accordance with a print job. The dryer system operates to intake and heat air from an internal region in which one or more electrical components of the printer are located. The dryer system directs the heated air through multiple outlets that are acutely angled with respect to a location or media of deposited printing material, to dry the printing material while cooling the internal region of the printer.

First claim

What is claimed is:

1. A printer comprising:
a print bar assembly to deposit printing material in accordance with a print job; and
a dryer system to intake and heat air from an internal region of the printer in which one or more electrical components of the printer are located, the dryer system to direct the heated air through multiple outlets that are acutely angled with respect to media of deposited printing material to dry the printing material while cooling the internal region of the printer.

2. The printer of claim 1 , further comprising:
a housing; and
a frame within the housing, the frame including multiple components that combine to provide a dryer zone and a media path for the media.

3. The printer of claim 2 , wherein the frame includes one or more recycling conduits that are positioned to draw heated air from a surrounding region through the dryer zone.

4. The printer of claim 2 , wherein the dryer system is to create an airflow within the printer between the dryer zone and an outlet for the heated air from the dryer system.

5. The printer of claim 1 , wherein the dryer system is to direct the outlet for the heated air to coincide with a location of a media eject slot of the printer.

6. The printer of claim 1 , wherein one or more recycling conduits are to recirculate a portion of the heated air back into a dryer zone, wherein the dryer zone is to combine the recirculated portion of the heated air with incoming air.

7. The printer of claim 1 , wherein the dryer system is thermally isolated within the printer.

8. The printer of claim 1 , wherein the dryer system includes a plurality of nozzles, each nozzle of the plurality is to output a corresponding portion of the heated air in a direction that is acutely angled with respect to the media traveling through the printer along a media path.

9. The printer of claim 1 , wherein at least a portion of the multiple outlets have an angle greater than 0 degrees with respect to a normal of a media surface.

10. The printer of claim 1 , wherein at least a portion of the multiple outlets have an angle between 10 and 40 degrees with respect to a normal of a media surface.

11. The printer of claim 1 , further comprising a frame to physically and thermally isolate the internal region.

12. The printer of claim 11 , wherein the frame includes a structure selected from the group consisting of: an air dam, a plastic ribs, and a baffle.

13. The printer of claim 1 , further comprising an impeller fan, the impeller fan to bring incoming air to a dryer zone, and to mix and pressurize the incoming air.

14. A method of operating a printer, the method comprising:
depositing ink on a media in accordance with a print job; and
drying the ink on the media by intaking air from an internal region in which one or more electrical components of the printer are located, heating the air, and directing the heated air through multiple outlets that are acutely angled with respect to a path of travel of the media, to dry the ink while cooling the internal region of the printer.

15. A dryer system comprising:
an intake system within a frame of a printer to intake air from an internal region of the printer in which one or more electrical components of the printer are located;
a heating element to heat the intaked air; and
multiple outlets that are acutely angled with respect to media, the individual outlets to directionally output the heated air in a direction that at least partially coincides with a path of travel of the media to dry ink on the media while cooling the internal region of the printer.
