Abstract

An example media handling system provides a print media (111) along a media path (131) and at least part of the media handling system includes an adhesive material for locating the print media (111) on the at least part of the media path (131).

First claim

The invention claimed is:

1. A media handling system for providing a print media along a media path, wherein at least part of the media handling system includes an adhesive material for locating a print media on the at least part of the media path,
wherein the adhesive material comprises a multi-mode adhesive material exhibiting different adhesive properties in different modes;
wherein the multi-mode adhesive material comprises a switchable adhesive material that switches between modes responsive to application of an external influence, wherein in a first mode, the adhesive material has adhesive properties and in a second mode has no adhesive properties.

2. The media handling system of claim 1 , wherein the system comprises a media-pick-up subsystem configured to retrieve print media and place the retrieved print media on the media path; a media-transport subsystem configured to advance print media along the media path; a media-hold-down subsystem configured to hold the print media flat for at least part of the media path; a media-output subsystem configured to output the print media from the media path, wherein at least one of the media-pick-up subsystem, media-transport subsystem, media-hold-down subsystem and media-output subsystem includes the adhesive material.

3. The media handling system of claim 1 , wherein the adhesive material has a sheer adhesion coefficient greater than 5 and a detachment force of less that 0.1 N/n when no shear force is applied.

4. The media handling system of claim 1 , wherein the adhesive material is arranged intermittently over a surface of the at least one element.

5. The media handling system of claim 1 , comprising a belt with the multi-mode adhesive material disposed on a surface of the belt, the system configured to release tension in the belt to release print media from the multi-mode adhesive material on the surface of the belt.

6. The media handling system of claim 1 , wherein the external influence switching the adhesive material between modes comprises strain on the adhesive.

7. The media handling system of claim 1 , wherein the external influence switching the adhesive material between modes comprises ultra-violet (UV) light.

8. The media handling system of claim 1 , wherein the external influence switching the adhesive material between modes comprises an electric or magnetic field.

9. A printing system comprising:
a print zone comprising an array of pens for printing a desired image on a print medium; and
a plurality of elements for handling print media along a media path from a supply of print media, through the print zone and to an output for printed print media,
wherein at least one element of the plurality of elements includes an adhesive material for adhering to print media for at least part of the media path;
wherein the adhesive material comprises a multi-mode adhesive material exhibiting different adhesive properties in different modes.

10. The printing system of claim 9 , wherein the multi-mode adhesive material comprises a gecko-inspired adhesive (GSA) in which the different modes are switched by a change in the shear force between the adhesive material and the print media.

11. The printing system of claim 9 , wherein at least one of the plurality of elements comprises one of media-pick-up subsystem; media-transport subsystem; media-hold-down subsystem; media-output subsystem.

12. The printing system of claim 9 , wherein the adhesive material has a sheer adhesion coefficient greater than 5 and a detachment force of less that 0.1 N/m when no shear force is applied.

13. The printing system of claim 9 , wherein the adhesive material is arranged intermittently over a surface of the at least one element.

14. The printing system of claim 9 , wherein the plurality of elements comprises a belt with the multi-mode adhesive material disposed on a surface of the belt, the printing system configured to release tension in the belt to release print media from the multi-mode adhesive material on the surface of the belt.

15. The printing system of claim 9 , wherein the different modes are switched by the application of an external influence.

16. A method of handling print media, the method comprising:
picking up print media from a supply of print media;
moving the print media along a media path from the print media supply to a print zone;
holding the print media in the print zone during printing on the print media; and
outputting printed print media alone the media path away from the print zone to output the printed print media;
wherein at least one of the picking, moving, holding or outputting of the print media is performed with a media handling structure comprising a surface for contacting the print media where the surface comprises an adhesive material for temporarily securing print media to that media handling structure; and
wherein the adhesive material comprises a multi-mode adhesive material, the multi-mode adhesive material exhibiting different adhesive properties in different modes.

17. The method claim 16 , wherein the multi-mode adhesive material comprises a gecko-inspired adhesive (GSA), the method comprising removing print media from the adhesive material in a direction that does not cause adherence with the GSA.

18. The method of claim 16 , wherein the multi-mode adhesive material comprises a switchable adhesive material having a first mode in which the switchable adhesive material has adhesive properties and a second mode in which the switchable adhesive material has non-adhesive properties, the method comprising switching the switchable adhesive material between the first and second modes.
