Benefits of technology

[0009]The present invention provides a technique of, when no target sheet exists in a sheet storage unit selected as a paper feed source, reliably notifying the user of an optimum sheet storage unit in which sheets should be replaced or set in a group to which the selected sheet storage unit belongs.

Problems solved by technology

However, when a print job requiring many paper sizes and paper types is executed and no necessary paper exists in a designated group, the operator cannot be instructed about a paper feed cassette of a paper size or paper type which should be changed.

Abstract

In a printing system which feeds a sheet from a plurality of sheet storage units and prints an image on the fed sheet, and a control method thereof, when a sheet storage unit selected as a paper feed source does not store sheets of a size designated by a print job, and a sheet storage unit which stores sheets of the size designated by the print job does not exist in a group to which the selected sheet storage unit belongs, the user is notified of a sheet storage unit in the group as a sheet storage unit which should store sheets.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a technique for arranging, grouping, and using a plurality of sheet storage units.[0003]2. Description of the Related Art[0004]In an image forming apparatus including a plurality of paper feed cassettes (sheet storage units), these paper feed cassettes are grouped and handled. According to this technique, for an input print job which designates a given paper feed cassette, even if paper in the given paper feed cassette runs out, the print job can be executed by feeding paper from another paper feed cassette of a group to which the given paper feed cassette belongs.[0005]Many companies have proposed methods for increasing the availability of an image forming apparatus by efficiently using a plurality of paper feed cassettes in a group. For example, there has been proposed a method of using first a paper feed cassette in which paper is left in a small amount, out of paper feed cassettes in...
