Printer roll feed mechanism

1. A method for loading print media in a printer, the method comprising:

rotating a print media roll having a leading edge in a first direction;

rotating in the first direction a vacuum roller positioned prior to a media guide in a media path;

detecting the leading edge of the print media with a media end detecting sensor positioned in the media path prior to the leading edge being received by the media guide;

rotating the print media roll in a second direction in response to detecting the leading edge of the print media prior to the leading edge being received by the media guide; and

guiding the print media along the media path with the vacuum roller.

2. The method of claim 1 , wherein the print media roll is rotated by a driving roller configured to rotate in a first direction and a second direction.

3. The method of claim 1 , wherein the first direction is opposite of the second direction.

4. The method of claim 1 , wherein the first direction is clockwise.

5. The method of claim 1 , wherein the second direction is counterclockwise.

6. The method of claim 1 , wherein the vacuum roller is perforated and operatively connected to a vacuum source.

7. The method of claim 1 , wherein the media end detecting sensor is positioned proximate to the vacuum roller and the print media, and prior to the media guide.

8. The method of claim 1 , wherein the print media is guided along a media path by the media guide positioned proximate to the vacuum roller.

9. The method of claim 1 , wherein at least a portion of the media guide is perforated, wherein another portion of the media guide corresponds to solid media guides.

10. The method of claim 1 , comprising:

moving the print media along the media path towards pinch rollers;

detecting the leading edge of the print media with a leading end detecting sensor positioned proximate to the pinch rollers;

removing vacuum from the vacuum roller in response to detecting the leading edge of the print media; and

guiding the print media forward with the pinch rollers.

11. A media feeding system, comprising:

a driver configured to rotate a media roll in a first direction;

a vacuum roller positioned before a media guide in a media feed path and configured to rotate in the first direction; and

a media end detecting sensor positioned before the media guide and after the vacuum roller in the media feed path, the media end detecting sensor being configured to detect a leading edge of the media;

wherein the driver rotates the media roll in a second direction opposite the first direction in response to the sensor detecting the leading end of the media prior to being received by the media guide.

12. The media feeding system of claim 11 , wherein the driver comprises a driving roller configured to rotate in a first direction and a second direction.

13. The media feeding system of claim 11 , wherein the vacuum roller is perforated and operatively connected to a vacuum source.

14. The media feeding system of claim 11 , wherein the media end detecting sensor is positioned proximate to the vacuum roller and the print media, and before the media guide.

15. The media feeding system of claim 11 , comprising the media guide positioned proximate to the vacuum roller along a length of a media path.

16. The media feeding system of claim 15 , wherein a first portion of the media guide is perforated and a second portion of the media guide is a solid media guide, wherein the first portion of the media guide comprises a plurality of vacuum holes which are in operative communication with a vacuum source.

17. The media feeding system of claim 11 , comprising:

pinch rollers positioned along the media feed path; and

a leading end detecting sensor located proximate to the pinch rollers, the sensor configured to detect the leading edge of the media;

wherein vacuum is removed from the vacuum roller and the media is guided forward by the pinch rollers in response to the leading end detecting sensor detecting the leading end of the media.

18. A printer, comprising:

a housing;

a printing mechanism positioned in the housing; and

a media feeding mechanism positioned in the housing, comprising:

a vacuum roller positioned in a media path prior to a media guide, the vacuum roller being configured to rotate in a first direction and push media along a media path,

a media end detecting sensor positioned in the media path prior to the media guide,

a driver configured to rotate a media roll in a second direction in response to the media end detecting sensor detecting a leading end of the media prior to being received by the media guide, and

a first portion of the media guide configured to guide media pushed by the vacuum roller along the media path.

19. The printer of claim 18 , wherein first portion of the media guide is perforated media guide, wherein a second portion of the media guide is a solid media guide.

20. The printer of claim 18 , comprising:

pinch rollers positioned along the media path; and

a leading end detecting sensor positioned proximate to the pinch rollers, the leading end detecting sensor being configured to detect the leading end of the media;

wherein vacuum is removed from the vacuum roller in response to detecting the leading edge of the media and the media is guided forward by the pinch rollers.
