Abstract

The image forming apparatus which comprises a plurality of sheet holding units each configured to hold a sheet and a printing unit configured to print an image, receives a print setting for a first type test chart image to be printed on sheets conveyed from all of the plurality of sheet holding units and for a second type test chart image to be printed on a sheet conveyed from at least one sheet holding unit of the plurality of sheet holding units, and controls the printing unit on a basis of the print setting to convey sheets from each of the plurality of sheet holding units and print the first type test chart image and following thereafter convey a sheet from the at least one sheet holding unit from among the plurality of sheet holding units and print the second type test chart image.

Claims (28)

1 . An image forming apparatus comprising:

a plurality of sheet holding units each that holds at least one sheet;

a printer that prints an image;

a user interface that receives

a print setting for a first type test chart image to be printed on each sheet conveyed from each of the plurality of sheet holding units and for a second type test chart image to be printed on another sheet conveyed from at least one sheet holding unit of the plurality of sheet holding units, the first type test chart image being for confirming a print position of the image printed by the printer, the second type test chart image being for confirming tone of the image printed by the printer, and

a controller that controls the printer on a basis of the print setting to convey each sheet from each of the plurality of sheet holding units and print the first type test chart image on the each sheet and following thereafter convey another sheet from the at least one sheet holding unit from among the plurality of sheet holding units and print the second type test chart image on the another sheet.

2 . The image forming apparatus according to claim 1 , wherein

the second type test chart image is a test chart image for confirming color deviation of each color of a plurality of toners for forming a color image.

3 . The image forming apparatus according to claim 1 , wherein

at least one of the first type test chart image and the second type test chart image includes a plurality of test chart images with different confirming perspectives.

4 . The image forming apparatus according to claim 1 , wherein the controller combines at least one of the first type test chart image and the second type test chart image with information identifying the sheet holding unit for conveying the sheet via the image combining unit.

5 . The image forming apparatus according to claim 4 , wherein

at least one of the first type test chart image and the second type test chart image is further combined with at least one of information identifying an image forming apparatus and a printed date and time.

6 . The image forming apparatus according to claim 1 , wherein

the print setting for the first type test chart image to be printed on sheets conveyed from all of the plurality of sheet holding units and for the second type test chart image to be printed on a sheet conveyed from the at least one sheet holding unit is set via a combination of a specific test chart type and a specific image processing mode.

7 . The image forming apparatus according to claim 1 , wherein

the print setting for the first type test chart image to be printed on sheets conveyed from all of the plurality of sheet holding units and for the second type test chart image to be printed on a sheet conveyed from the at least one sheet holding unit is set via mode designation.

8 . The image forming apparatus according to claim 1 , wherein

the print setting includes a setting for a number of copies of at least one of the first type test chart image and the second type test chart image, and

the controller controls the printer to print repeatedly the number of copies of at least one of the first type test chart image and the second type test chart image.

9 . A control method for an image forming apparatus comprising a plurality of sheet holding units each configured to hold a sheet and a printer that prints an image,

the method comprising:

receiving, via a user interface, a print setting for a first type test chart image to be printed on each sheet conveyed from each of the plurality of sheet holding units and for a second type test chart image to be printed on another sheet conveyed from at least one sheet holding unit, the first type test chart image being for confirming a print position of the image printed by the printer, the second type test chart image being for confirming tone of the image print by the printer; and

controlling the printer on a basis of the print setting to convey each sheet from each of the plurality of sheet holding units and print the first type test chart image on the each sheet and following thereafter convey another sheet from the at least one sheet holding unit from among the plurality of sheet holding units and print the second type test chart image on the another sheet.

10 . A non-transitory computer-readable storage medium, the storage medium storing a program for causing a computer to execute each step of a method of controlling an image forming apparatus comprising a control unit, a plurality of sheet holding units each configured to hold a sheet, and a printer that prints an image,

the method comprising:

receiving, via a user interface, a print setting for a first type test chart image to be printed on each sheet conveyed from each of the plurality of sheet holding units and for a second type test chart image to be printed on another sheet conveyed from at least one sheet holding unit, the first type test chart image being for confirming a print position of the image printed by the printer, the second type test chart image being for confirming tone of the image printed by the printer; and

controlling the printer on a basis of the print setting to convey each sheet from each of the plurality of sheet holding units and print the first type test chart image on the each sheet and following thereafter convey another sheet from the at least one sheet holding unit from among the plurality of sheet holding units and print the second type test chart image on the another sheet.
