Abstract
A page-wide inkjet printer for determining a drying time of a print swath of ink deposited on a sheet of media by a fixed printhead spanning a width of a printing zone in a subscan direction. The printer has a controller communicatively coupled to each of the printhead and a moveable gloss sensor or a scan bar for processing a respective output response for the determining the drying time of the print swath.
Claims10
A method for controlling operation of a printer, comprising:
- advancing a sheet of print media in a media feed direction to a first position;
- depositing, by a printhead, a print swath along a scan direction on the sheet of print media;
- determining a gloss value of the print swath based on a detected amount of specular reflection from the ink swath;
- determining if the sheet of print media is moveable without smearing based on the determined gloss value;
- upon the condition that the sheet of print media is determined to be moveable without smearing, advancing the sheet of print media in the media feed direction to a second position;
- and
- upon the condition that the sheet of print media is determined to be not moveable without smearing, maintaining the sheet of print media in the first position.
