Patent Images
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.

Abstract
A media feeding system comprises a driver configured to rotate a media roll in a first direction; a vacuum roller positioned in a media feed path and configured to rotate in the first direction; and a media end detecting sensor positioned 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.

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. - View Dependent Claims (12, 13, 14, 15, 16, 17)

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. - View Dependent Claims (19, 20)
