## Abstract

An image forming apparatus that uses set sheet information and is capable of reducing time and effort in replenishing sheets. At least one sheet feed cassette stores sheets. Sheet information of the sheet feed cassette is set according to specifications of the stored sheets using a setting screen displayed on a console panel. Print processing is performed using sheets corresponding to information on sheets included in a print job. It is determined whether or not the information on sheets corresponds to the sheet information of the sheet feed cassette. A sensor detects operations of opening and closing the sheet feed cassette. Even when an operation of opening the cassette or removal of the same has been detected, if the sheet information of the cassette corresponds to the information on sheets, the console panel does not display the setting screen.

## Claims

### Claim 1

An image forming apparatus comprising:
a plurality of sheet feed cassettes configured to store sheets;
an image forming unit configured to form an image on a sheet;
a sensor configured to detect an opening or closing of each sheet feed cassette;
a display unit;
a processor; and
a memory in communication with the processor, the memory storing instructions, which, when executed by the processor, cause the image forming apparatus to:
receive a print job in which a sheet size and a sheet type are designated;
select, from among the plurality of sheet feed cassettes, a sheet feed cassette corresponding to the sheet size designated in the print job;
in a case where a sheet type of the selected sheet feed cassette matches with the sheet type designated in the print job, control the image forming unit to form an image on a sheet fed from the selected sheet feed cassette, wherein, in a case where the sheet type of the selected sheet feed cassette does not match with the sheet type designated in the print job, an execution of the print job is suspended;
in a case where an opening or closing of one of the plurality of sheet feed cassettes is detected while the execution of the print job is suspended, determine whether the sheet feed cassette of which the opening or closing is detected matches with the selected sheet feed cassette;
in a case where it is determined that the sheet feed cassette of which the opening or closing is detected matches with the selected sheet feed cassette, cause the display unit to display a setting screen for setting a sheet type for the sheet feed cassette of which the opening or closing is detected; and
in a case where the sheet type set through the setting screen matches with the sheet type designated in the print job, control the image forming unit to form an image on a sheet fed from the sheet feed cassette of which the sheet type is set.

### Claim 2 (depends on 1)

The image forming apparatus according to claim 1, wherein the print job is held in queue.

### Claim 3 (depends on 1)

The image forming apparatus according to claim 1, wherein in a case where an opening or closing is detected while a sheet out occurs on the selected sheet feed cassette, the processor does not cause the display unit to display the setting screen.

### Claim 4 (depends on 1)

The image forming apparatus according to claim 1, wherein in a case where the sheet type of the selected sheet feed cassette does not match with the sheet type designated in the print job, the processor stores error information indicating that there is a mismatch between the sheet types into a memory.

### Claim 5

A method of controlling an image forming apparatus comprising a plurality of sheet feed cassettes configured to store sheets, an image forming unit configured to form an image on a sheet, a sensor configured to detect an opening or closing of each sheet feed cassette, and a display unit, the method comprising:
receiving a print job in which a sheet size and a sheet type are designated;
selecting, from among the plurality of sheet feed cassettes, a sheet feed cassette corresponding to the sheet size designated in the print job;
in a case where a sheet type of the selected sheet feed cassette matches with the sheet type designated in the print job, controlling the image forming unit to form an image on a sheet fed from the selected sheet feed cassette, wherein, in a case where the sheet type of the selected sheet feed cassette does not match with the sheet type designated in the print job, an execution of the print job is suspended;
in a case where an opening or closing of one of the plurality of sheet feed cassettes is detected while the execution of the print job is suspended, determining whether the sheet feed cassette of which the opening or closing is detected matches with the selected sheet feed cassette;
in a case where it is determined that the sheet feed cassette of which the opening or closing is detected matches with the selected sheet feed cassette, causing the display unit to display a setting screen for setting a sheet type for the sheet feed cassette of which the opening or closing is detected; and
in a case where the sheet type set through the setting screen matches with the sheet type designated in the print job, controlling the image forming unit to form an image on a sheet fed from the sheet feed cassette of which the sheet type is set.

### Claim 6

A non-transitory computer-readable storage medium storing a computer-executable program for executing a method of controlling an image forming apparatus comprising a plurality of sheet feed cassettes configured to store sheets, an image forming unit configured to form an image on a sheet, a sensor configured to detect an opening or closing of each sheet feed cassette, and a display unit, the method comprising:
receiving a print job in which a sheet size and a sheet type are designated;
selecting, from among the plurality of sheet feed cassettes, a sheet feed cassette corresponding to the sheet size designated in the print job;
in a case where a sheet type of the selected sheet feed cassette matches with the sheet type designated in the print job, controlling the image forming unit to form an image on a sheet fed from the selected sheet feed cassette, wherein, in a case where the sheet type of the selected sheet feed cassette does not match with the sheet type designated in the print job, an execution of the print job is suspended;
in a case where an opening or closing of one of the plurality of sheet feed cassettes is detected while the execution of the print job is suspended, determining whether the sheet feed cassette of which the opening or closing is detected matches with the selected sheet feed cassette;
in a case where it is determined that the sheet feed cassette of which the opening or closing is detected matches with the selected sheet feed cassette, causing the display unit to display a setting screen for setting a sheet type for the sheet feed cassette of which the opening or closing is detected; and
in a case where the sheet type set through the setting screen matches with the sheet type designated in the print job, controlling the image forming unit to form an image on a sheet fed from the sheet feed cassette of which the sheet type is set.
