Abstract
An ink patch is printed on a swath of media, by an inkjet-printing mechanism of an inkjet-printing device. Printing the ink patch takes a first length of time. The ink patch printed on the swath is heated at a first temperature less than a second temperature specified for the first length of time the inkjet-printing mechanism takes to print the ink patch. A second length of time is waited. A total length of time the swath is heated is at least substantially equal to the first length of time plus the second length of time.
Claims15
A method for calibrating an inkjet-printing mechanism of an inkjet-printing device, comprising:
- printing an ink patch on a swath of media, by the inkjet-printing mechanism, where printing the ink patch takes a first length of time;
- heating the swath at a first temperature less than a second temperature specified for the first length of time the inkjet-printing mechanism takes to print the ink patch;
- and,
- waiting a second length of time, such that a total length of time the swath is heated is at least substantially equal to the first length of time plus the second length of time.
A fluid-ejection device comprising:
- a fluid-ejection mechanism to eject fluid onto a swath of media to form a patch on the swath;
- a heating mechanism to heat the swath at a temperature less than a specified temperature for a first length of time the fluid-ejection mechanism takes to print the patch;
- and,
- a mechanism to wait a second length of time, such that a total length of time the swath is heated is at least substantially equal to the first length of time plus the second length of time.
An inkjet-printing device comprising:
- means for printing an ink patch on the swath;
- means for heating the ink patch printed on the swath at a temperature less than a specified temperature for a first length of time the inkjet-printing mechanism takes to print the ink patch;
- means for waiting a second length of time, such that a total length of time the swath is heated is at least substantially equal to the first length of time plus the second length of time.
