Image forming apparatus and image forming method

Abstract

The invention provides an image forming apparatus and an image forming method. The image forming apparatus of the present invention includes a paper type detection unit, a type determination unit, a paper search unit, and a paper change unit. The paper type detection unit detects the type of paper conveyed from the paper feeding cassette using a sensor. The type determination unit determines whether the type of paper has changed during printing. When the type of paper is changed during printing, the paper search unit searches for an appropriate paper feeding cassette containing the same type of paper as the paper before the change. When the search result shows that the appropriate paper feeding cassette exists, the paper changing unit processes the paper whose type has been changed, and restarts conveyance of the paper from the existing appropriate paper feeding cassette. According to the present invention, it is possible to unify the paper types of printed matter.

Description

technical field [0001] The present invention relates to an image forming apparatus and an image forming method, and more specifically, to an image forming apparatus and an image forming method capable of unifying the types of sheets of printed matter. Background technique [0002] Conventionally, in image forming apparatuses such as digital multi-function peripherals, copiers, and printers, there are many techniques for detecting the type of paper (sheet) and applying them to image formation. For example, an image forming apparatus is disclosed that uses a media sensor to discriminate the type of paper in each paper feeding stage. In this apparatus, the type of sheet is not set by the user, but is automatically detected in the main body of the image forming apparatus. [0003] In an image forming apparatus including a paper feeding cassette, a user may mistakenly replenish a different type of paper with paper remaining in the paper feeding cassette. In this case, there ari...

AI Technical Summary

Problems solved by technology

In this case, there is a problem that the paper is printed on different types of paper in the printing configuration.

In particular, when using printed materials as distribution materials, different types of printed materials may be mixed in the distribution materials, which may cause discomfort to users who receive the distribution materials

Therefore, in the conventional image forming apparatus, there is a problem that the paper types of the printed matter cannot be unified for the entire printed matter.
