Abstract

Examples described herein include a print media edge repair system that includes a first repair element disposed adjacent to a media handling path to repair a leading edge of a sheet of print media as the sheet of print media moves into a position relative to a printing system associated with the print media edge repair system. The print media repair system may also include a second repair element disposed opposite the first repair element across the media handling path to repair a trailing edge of the sheet of print media as the sheet of print media moves into the position relative to a printing system.

First claim

What is claimed is:

1. A system comprising:
a first repair element disposed adjacent to a media handling path to repair a leading edge of a sheet of print media as the sheet of print media moves along a first direction into a position relative to a printing system;
a second repair element disposed opposite the first repair element across the media handling path to repair a trailing edge of the sheet of print media as the sheet of print media moves along the first direction into the position relative to the printing system, wherein the first repair element and the second repair element are to simultaneously repair the corresponding leading edge and trailing edge of the sheet of print media as the sheet of print media moves into the position; and
a guide element to guide, along a second direction, the sheet of print media after the repairs by the first repair element and the second repair element, toward a print engine to apply a printing material to a surface of the sheet of print media, wherein the second direction is different from and angled with respect to the first direction, and wherein the leading edge and the trailing edge of the sheet of print media are relative to the media handling path as the sheet of print media moves along the second diretion.

2. The system of claim 1 , further comprising a damage detection device to determine damage to the leading edge or the trailing edge, wherein the first repair element is to selectively repair the leading edge in response to the detection device determining there is damage to the leading edge, and the second repair element is to selectively repair the trailing edge in response to the damage detection device determining there is damage to the trailing edge.

3. The system of claim 2 , wherein the damage detection device comprises an imaging device or a contact sensor.

4. The system of claim 1 , wherein the first repair element and the second repair element comprise corresponding abrasive elements or wetting elements.

5. The system of claim 1 , wherein the first repair element and the second repair element are to simultaneously repair the corresponding leading edge and trailing edge in a single operation.

6. The system of claim 1 , wherein the first repair element or the second repair element comprises a roller.

7. The system of claim 6 , wherein the roller is coated with an abrasive material to repair the corresponding leading edge or trailing edge.

8. The system of claim 1 , wherein the first repair element or the second repair element comprises a blade to repair the corresponding leading edge or trailing edge.

9. The system of claim 1 , wherein the first repair element or the second repair element comprises a porous material to apply a liquid wetting agent to repair the corresponding leading edge or trailing edge.

10. The system of claim 1 , wherein the second direction is orthogonal to the first direction.

11. The system of claim 1 , further comprising another guide element to guide the sheet of print media along the second direction after the repairs by the first repair element and the second repair element.
