Problems solved by technology

This can cause problems: waste of print media and contamination inside the imaging device due to missing printed images
In contrast, traditional color registration methods require complex arithmetic operations or are sensitive to errors caused by noise components in the registration marks

Abstract

A medium detecting device to detect information corresponding to a printing medium fed through a medium transport path, includes a detecting unit to detect a contour form information of the printing medium; and a discriminating unit to determine a format of the printing medium and feeding information based on the contour form information of the printing medium detected by the detecting unit.

Description

technical field [0001] The invention relates to a medium detection device and method, an imaging device using the medium detection device and an image output method thereof. Background technique [0002] Conventional printers use various printing media in different standard formats, and have at least one printing media feeding unit for loading the printing media. The print medium feeding unit includes: a cassette loaded with print media in a standard format and a multi-purpose tray loaded with print media in a non-standard format. In addition, the printer draws print media from a print media feed unit that is loaded with print media of an appropriate size for printing an image. [0003] However, if the printing medium has a format different from that of the standard format, a problem occurs when loading the printing medium in the printing medium feeding unit. That is, if a printing medium different in size from the printing image (for example, the size of the printing medi...
