Abstract
Apparatuses and methods for detecting error in loading print media in a printing device are disclosed. An apparatus embodiment includes a width adjuster position sensor that determines a position of a print medium width adjuster, a width sensor that measures a width of a print medium, and a computing device that compares the width adjuster position with the print medium width, and verifies that the width adjuster is properly positioned for the print medium width. Another embodiment includes a length adjuster position sensor that determines a position of a print medium length adjuster, a length sensor that measures a length of the print medium, and a computing device that compares the length adjuster position with the print medium length, and verifies that the length adjuster is properly positioned for the print medium length. A method embodiment includes determining a position of a width adjuster, measuring a width of a print medium, comparing the width adjuster position with the print medium width, and prompting a user to properly position the width adjuster when the width adjuster is improperly positioned for the print medium width. Another method embodiment includes determining …
