Abstract
Sensing when an inkjet printer is out of ink during printing is disclosed. Buffer color information for a swath to be printed next on a sheet by the printer is evaluated. The printed color information for the swath is then measure as the swath is printed on the sheet. If the printer color information is less than substantially equal to the buffer color information, one or more out-of-ink actions, such as notifying the user and/or aborting printing, are performed. A printer performing such sensing is also disclosed.
