Abstract
A method of an embodiment of the invention determines whether at least a portion of an image to be formed on a media sheet on a swath-by-swath basis by an image-formation mechanism includes one or more bar codes having a height that is less than a height of a swath of the image-formation mechanism. The mechanism adjusts the swath of the image-formation mechanism so that the bar codes are formed as part of the image on the media sheet within a single swath by the image-formation mechanism.

A method comprising:
- determining whether at least a portion of an image to be formed on a media sheet on a swath-by-swath basis by an image-formation mechanism includes one or more bar codes having a height that is less than a height of a swath of the image-formation mechanism;
- adjusting the swath of the image-formation mechanism so that the bar codes are formed as part of the image on the media sheet within a single swath by the image-formation mechanism;
- wherein adjusting the swath of the image-formation mechanism comprises either
- performing a short media sheet advance prior to forming the bar codes on the media sheet or
- reducing a media sheet advance performed after each swath of the image is formed by the image-formation mechanism
- so that the bar codes are formed within a single swath by the image-formation mechanism.

8-10. (canceled)
An image-formation device comprising:
- an image-formation mechanism to form an image on a media sheet on a swath-by-swath basis;
- a media-sheet advancement mechanism to advance the media sheet after each swath of the image has been formed on the media sheet by the image-formation mechanism;
- and,
- a bar-code correction mechanism to determine whether the image contains one or more bar codes and to adjust an amount by which the media sheet is advanced by the media-sheet advancement mechanism so that the bar codes are each formed within a single swath by the image-formation mechanism.
An image-formation device comprising:
- first means for forming an image on a media sheet on a swath-by-swath basis;
- second means for advancing the media sheet after each swath of the image has been formed on the media sheet by the first means;
- and,
- third means for determining whether the image contains one or more bar codes and for adjusting an amount by which the media sheet is advanced by the second means so that the bar codes are each formed within a single swath by the first means.
(canceled)
A computer-readable medium having a computer program stored thereon comprising:
- a first computer program part to determine whether at least a portion of an image to be formed on a media sheet on a swath-by-swath basis includes one or more bar codes having a height that is less than a height of a swath;
- and,
- a second computer program part to adjust the swath so that the bar codes are formed on the media sheet within a single swath;
- and
- wherein the second computer program part is to cause a short media sheet advance to be performed prior to any of the portion of the image being formed on the media sheet.
