Abstract

In one example, a media support includes a platen and multiple suction cups in the platen. Each suction cup in the platen has a port through which air may be evacuated from the cup.

First claim

The invention claimed is:

1. A media support, comprising:
a platen and multiple suction cups in the platen, each suction cup having a port through which air may be evacuated from the suction cup and a flexible rim surrounding the port along an outer perimeter of the suction cup; and
a detachable plate configured to cover at least part of the platen, the plate having holes therein through which vacuum may be applied to media on the plate and each hole in the plate aligned with a suction cup or a vacuum hole in the platen when the plate is attached to the platen.

2. The media support of claim 1 , wherein the density of suction cups in the platen varies between different parts of the platen.

3. The media support of claim 1 , wherein each suction cup comprises a discrete part embedded in the platen.

4. The media support of claim 1 , wherein each suction cup comprises an integral part of the platen.

5. The media support of claim 1 , wherein the rim of each suction cup protrudes from a face of the platen.

6. The media support of claim 5 , wherein the rim is formed at the perimeter of a flexible ring surrounding the port in a space such that the ring may flex into the space away from the face of the platen when a media supported on the face of the platen is sucked onto the rim.

7. The media support of claim 6 , wherein each suction cup includes multiple ridges each extending radially out from the port toward the rim.

8. A media support, comprising:
a flat, rigid platen having multiple suction cups therein to apply a vacuum to media on the platen, each suction cup having a port through which air may be evacuated from the suction cup; and
a detachable plate configured to cover at least part of the platen, the plate having holes therein through which vacuum may be applied to media on the plate and each hole in the plate aligned with a suction cup or a vacuum hole in the platen when the plate is attached to the platen.

9. The media support of claim 8 , wherein the plate comprises multiple detachable plates each configured to cover part of the platen and each having holes therein through which vacuum may be applied to media on the plate, each hole in each plate aligned with a suction cup or a vacuum hole in the platen when the plate is attached to the platen.

10. The media support of claim 9 , further comprising multiple vacuum holes in the platen interspersed among the suction cups and wherein some of the holes in each plate are aligned with a suction cup in the platen and some of the holes in each plate are aligned with a vacuum hole in the platen.

11. The media support of claim 8 , wherein the density of suction cups in the platen varies between different parts of the platen.

12. The media support of claim 8 , wherein each suction cup comprises a discrete part embedded in the platen.

13. The media support of claim 8 , wherein each suction cup comprises an integral part of the platen.

14. The media support of claim 8 , wherein each suction cup includes a rim surrounding the port, the rim protruding from a face of the platen.

15. The media support of claim 14 , wherein the rim is formed at the perimeter of a flexible ring surrounding the port in a space such that the ring may flex into the space away from the face of the platen when a media supported on the face of the platen is sucked onto the rim.

16. The media support of claim 15 , wherein each suction cup includes multiple ridges each extending radially out from the port toward the rim.
