Abstract

An image forming apparatus includes a search unit that, in a case where job data in which a sheet type in sheet feeding setting information is specified is received, searches for a sheet cassette of which a sheet type in sheet setting information of the sheet cassette is unregistered, and an execution unit that, in a case where, as a result of the search, there is a sheet cassette of which a sheet type in the sheet setting information is unregistered, executes processing of sheet type detection for detecting a type of a sheet set in the sheet cassette.

First claim

What is claimed is:

1. A printing apparatus comprising:
sheet holding units including a first sheet holding unit for which a sheet type is registered and a second sheet holding unit for which a sheet type is not registered;
a selecting unit configured to select the second sheet holding unit as a sheet feeding source in accordance with a sheet type designated by a print job being not registered in the sheet holding units;
a detecting unit configured to detect a sheet type of the sheet fed from the second sheet holding unit selected by the selecting unit;
a determining unit configured to determine whether the sheet type designated by the print job matches the sheet type detected by the detecting unit; and
a printing unit configured to print an image on a sheet fed from the second sheet holding unit selected by the selecting unit in a case where the determining unit determines that the sheet type designated by the print job matches the sheet type detected by the detecting unit.

2. The printing apparatus according to claim 1 , further comprising a registering unit configured to register a sheet type for the sheet holding units.

3. The printing apparatus according to claim 1 ,
wherein the sheet type is a thickness of the sheet or a surface property.

4. The image forming apparatus according to claim 1 , further comprising
a control unit configured to suspend printing by the printing unit in a case where the determining unit determines that the sheet type designated by the print job does not match the sheet type detected by the detecting unit.

5. The image forming apparatus according to claim 4 , wherein the control unit performs control so that a blank sheet is output when the printing by the printing unit is suspended.

6. A control method for controlling a printing apparatus which has sheet holding units including a first sheet holding unit for which a sheet type is registered and a second sheet holding unit for which a sheet type is not registered, the control method comprising:
selecting the second sheet holding unit as a sheet feeding source in accordance with a sheet type designated by a print job being not registered in the sheet holding units;
detecting a sheet type of the sheet fed from the selected second sheet holding unit;
determining whether the sheet type designated by the print job matches the detected sheet type; and
printing an image on the sheet fed from the selected second sheet holding unit in a case where it is determined that the sheet type designated by the print job matches the detected sheet type.

7. A non-transitory computer-readable storage medium storing computer executable instructions that causes a computer to perform a control method for controlling a printing apparatus which has sheet holding units including a first sheet holding unit for which a sheet type is registered and a second sheet holding unit for which a sheet type is not registered, the control method comprising:
selecting the second sheet holding unit as a sheet feeding source in accordance with a sheet type designated by a print job being not registered in the sheet holding units;
detecting a sheet type of the sheet fed from the selected second sheet holding unit;
determining whether the sheet type designated by the print job matches the detected sheet type; and
printing an image on the sheet fed from the selected second sheet holding unit in a case where it is determined that the sheet type designated by the print job matches the detected sheet type.
