Abstract

Examples disclosed herein relate to a device including a media ramp, in examples, the device includes a scanner disposed in a scan zone to image a medium traveling across the scan zone; a transparent member disposed over the scan zone; a media ramp disposed adjacent to the scan zone to direct the medium to an exit; and a film element disposed underneath the transparent member and adjacent to the scan zone at a first end and disposed to extend over at least a portion of the media ramp at a second end.

First claim

What is claimed is:

1. A device, comprising:
a scanner disposed in a scan zone to image a medium traveling across the scan zone;
a transparent member disposed over the scan zone;
a media ramp disposed adjacent to the scan zone to direct the medium to an exit; and
a first film element disposed underneath the transparent member and adjacent to the scan zone at a first end and disposed to extend over at least a portion of the media ramp at a second end.

2. The device of claim 1 , further comprising:
a second film element spaced apart from the first film element to form a channel there between, the second film disposed adjacent to the scan zone at a first end and disposed to extend over at least a portion of the media ramp at a second end.

3. The device of claim 2 , further comprising:
a third film element spaced apart from the first element and the second film element, the third film disposed adjacent to the scan zone at a first end and disposed to extend over at least a portion of the media ramp at a second end.

4. The device of claim 1 , further comprising:
a calibration label disposed over the scan zone and underneath the transparent member and disposed to extend over at least a portion of the media ramp, wherein the first end of the first film element is disposed inside the calibration label.

5. The device of claim 1 , wherein the first film element is composed of a biaxially-oriented polyethylene terephthalate.

6. An imaging device, comprising:
a scanner disposed in a scan zone to image a medium;
a transparent member disposed over the scan zone;
a media ramp disposed adjacent to the scan zone to guide the medium to an exit path;
a first film element disposed underneath the transparent member and adjacent to the scan zone at a first end and disposed to extend over at least a portion of the media ramp at a second end; and
a second film element spaced apart from the first film element to form a channel there between, the second film disposed underneath the transparent member and adjacent to the scan zone at a first end and disposed to extend over at least a portion of the media ramp at a second end.

7. The imaging device of claim 6 , further comprising:
a calibration label disposed over the scan zone and underneath the transparent member and disposed to extend over at least a portion of the media ramp,
wherein the first end of the first film element and the first end of the second film element are disposed inside the calibration label.

8. The imaging device of claim 7 , further comprising:
a third film element disposed inside the channel and spaced apart from the first element and the second film element, the third film disposed adjacent to the scan zone at a first end and disposed to extend over at least a portion of the media ramp at a second end.

9. The imaging device of claim 6 , further comprising:
a fourth film element disposed outside the channel and spaced apart from the first element and the second film element, the fourth film element disposed adjacent to the scan zone at a first end and disposed to extend over at least a portion of the media ramp at a second end.

10. The imaging device of claim 6 , wherein the first film element and the second film element are composed of a biaxially-oriented polyethylene terephthalate.

11. An imaging device, comprising:
a scanner disposed in a scan zone to image a medium;
a transparent member disposed over the scan zone;
a media ramp disposed adjacent to the scan zone to direct the medium to an exit path of an automatic document feeder;
a first film element disposed underneath the transparent member and adjacent to the scan zone at a first end and disposed to extend over at least a portion of the media ramp at a second end;
a second film element spaced apart from the first film element to form a channel there between, the second film disposed underneath the transparent member and adjacent to the scan zone at a first end and disposed to extend over at least a portion of the media ramp at a second end; and
a calibration label disposed over the scan zone and underneath the transparent member and disposed to extend over at least a portion of the media ramp, the first end of the first film element and the first end of the second film element are disposed inside the calibration label.

12. The imaging device of claim 11 , wherein the first film element and the second film element are composed of a biaxially-oriented polyethylene terephthalate.

13. The imaging device of claim 11 , further comprising:
a third film element spaced apart from the first element and the second film element, the third film disposed underneath the transparent member and adjacent to the scan zone at a first end and disposed to extend over at least a portion of the media ramp at a second end.

14. The imaging device of claim 13 , wherein the third film element is disposed in the channel to further define a first channel and a second channel.

15. The imaging device of claim 14 , further comprising:
a fourth film element disposed outside the channel and spaced apart from the first element and the second film element, the fourth film element disposed underneath the transparent member and adjacent to the scan zone at a first end and disposed to extend over at least a portion of the media ramp at a second end.
