Abstract

Various embodiments illustrated herein disclose a printing apparatus comprising a media supply spool configured to supply print media along a media path. The printing apparatus further comprises a first media sensor positioned in a first plane in the printing apparatus. Further, the printing apparatus comprises a second media sensor positioned in a second plane in the printing apparatus. Additionally, the printing apparatus comprises a first media guide defining a section of the media path, wherein extremities of the first media guide are positioned to be at a negative offset from the second plane.

Claims (30)

1. A printing apparatus comprising:

a media supply spool configured to supply print media along a media path;

a first media sensor positioned in a first plane in the printing apparatus;

a second media sensor positioned in a second plane in the printing apparatus; and

a first media guide defining a section of the media path, wherein extremities of the first media guide are positioned to be at a negative offset from the second plane.

2. The printing apparatus of claim 1 , wherein the first media guide further comprises a first planar section and a second planar section.

3. The printing apparatus of claim 2 , wherein the first media sensor is positioned between the first planar section and the second planar section.

4. The printing apparatus of claim 2 , wherein the first planar section and the second planar section may correspond to the extremities of the first media guide.

5. The printing apparatus of claim 2 further comprising a second media guide defining the section of the media path, wherein the second media guide is spaced apart from the first media guide, and wherein the second media guide comprises a second media guide section.

6. The printing apparatus of claim 5 , wherein the second media guide is spaced apart from the first media guide along a vertical axis of the printing apparatus by a predetermined distance.

7. The printing apparatus of claim 5 , wherein the first media guide comprises a first media guide section, where the first media guide section comprises a peak region, and wherein the second media guide section comprises a valley region.

8. The printing apparatus of claim 7 , wherein the first media sensor is disposed on the peak region and the second media sensor is disposed in the valley region.

9. The printing apparatus of claim 8 , wherein the peak region is configured to be received within the valley region, wherein the reception of the peak region within the valley region ensures that the print media remains in contact with the peak region of the first media guide.

10. The printing apparatus of claim 5 , wherein the first media guide section and the second media guide section have an arch profile with a first radius of curvature and a second radius of curvature, respectively.

11. The printing apparatus of claim 10 , wherein the second radius of curvature is greater than the first radius of curvature.

12. A media guide assembly for a printing apparatus, the media guide assembly comprising:

a first media guide configured to define a section of a media path in the printing apparatus, wherein the first media guide comprises a first media guide section having an arch profile with a first radius of curvature,

wherein the first media guide section is configured to receive a first media sensor, and

wherein at least the arch profile of the first media guide section facilitates a print media, traversing along the media path, to abut with the first media sensor.

13. The media guide assembly of claim 12 further comprising a second media guide configured to define the section of the media path, wherein the second media guide comprises a second media guide section having the arch profile with a second radius of curvature, and wherein the second media guide is configured to be spaced apart from the first media guide along a vertical axis of the printing apparatus, and wherein the first media guide is configured to be parallel to the second media guide.

14. The media guide assembly of claim 13 , wherein the first media guide section comprises a peak region, and wherein the second media guide section comprises at a valley region, wherein the second media guide is configured to receive a second media sensor.

15. The media guide assembly of claim 14 , wherein the first media sensor comprises a light transmitter and the second media sensor comprises a light receiver, wherein the peak region of the first media guide section is configured to receive the light transmitter in the peak region.

16. The media guide assembly of claim 15 , wherein the second media guide section is configured to receive the light receiver in the valley region.

17. The media guide assembly of claim 13 wherein the second media guide is configured to be positioned at a predetermined distance from the second media guide along the vertical axis of the printing apparatus.

18. The media guide assembly of claim 13 , wherein the second radius of curvature is greater than the first radius of curvature.

19. A printing apparatus comprising:

a media supply spool configured to supply print media along a media path;

a media sensor comprising a light transmitter and a light receiver, wherein the light transmitter is positioned to be spaced apart from the media path along a vertical axis of the printing apparatus, wherein light receiver is positioned to be spaced apart from the media path along the vertical axis of the printing apparatus, wherein the media path is defined to be between the light receiver and the light transmitter; and

a first media guide defining a section of the media path, wherein the first media guide comprises a first media guide section a first planar section and a second planar section, wherein the first media guide section is defined to be between the first planar section and the second planar section, wherein the light receiver is positioned on the first media guide section, and wherein the first planar section and the second planar section are defined to be above a position of the light transmitter along the vertical axis of the printing apparatus.

20. The printing apparatus of claim 19 further comprising a second media guide defining the section of the media path, wherein the second media guide is spaced apart from the first media guide, and wherein the second media guide comprises a second media guide section.
