Abstract

An image forming apparatus that executes a job for output processing of image data includes a storage unit configured to store job information about an executed job and image data corresponding to an output based on the job as a job history corresponding to the job, and a recording unit configured to record information about an error that has occurred when the job history is stored, wherein, in conversion processing for storing the image data in an image format with text information as the job history, when an error occurs in the processing of a part of pages included in a target job, the storage unit stores image data corresponding to the job in the job history in a predetermined format different from the image format with the text information, and the recording unit records information about the part of the pages as the information about the error.

Claims (24)

1 . An image forming apparatus that executes a job, the image forming apparatus comprising:

one or more processors; and

at least one memory storing executable instructions, which when executed by the one or more processors, cause the image forming apparatus to perform operations comprising:

storing image data corresponding to output processing of image data by executing a job;

storing job information corresponding to the job;

performing first conversion processing for converting images of respective pages of the image data into a first format, the first format being an image format with text information;

determining that the first conversion processing is unsuccessful based on a failure to convert an image of a first page of the image data into the first format;

recording error information indicating that the failure to convert the image of the first page into the first format has occurred;

performing second conversion processing for converting the image of the first page into a second format different from the first format based on the error information indicating the failure to convert the image of the first page into the first format, the image of the first page being converted into first converted image data in the second format by the performing the second conversion processing; and

storing a job history corresponding to the job, wherein the job history includes the job information and the first converted image data as data of the first page of the job.

2 . The image forming apparatus according to claim 1 , the operations further comprising:

transmitting the job history and the error information to an information processing apparatus via a network.

3 . The image forming apparatus according to claim 1 , wherein the failure to convert the image of the first page into the first format is a failure of an optical character recognition/reader (OCR) for extracting the text information in the first conversion processing.

4 . The image forming apparatus according to claim 1 , wherein the first converted image data corresponding to the image of the first page converted into the second format is only generated when the failure to convert the image of the first page into the first format occurs.

5 . The image forming apparatus according to claim 1 , wherein the job history further includes second converted image data, in the first format, produced by successful the first conversion processing of images of one or more pages of the job other than the first page.

6 . The image forming apparatus according to claim 1 , wherein the second format is an image format without text information.

7 . A control method in an image forming apparatus that executes a job, the control method comprising:

storing image data corresponding to output processing of image data by executing a job;

storing job information corresponding to the job;

performing first conversion processing for converting images of respective pages of the image data into a first format, the first format being an image format with text information;

determining that the first conversion processing is unsuccessful based on a failure to convert an image of a first page of the image data into the first format;

recording error information indicating that the failure to convert the image of the first page into the first format has occurred;

performing second conversion processing for converting the image of the first page into a second format different from the first format based on the error information indicating the failure to convert the image of the first page into the first format, the image of the first page being converted into first converted image data in the second format by the performing the second conversion processing; and

storing a job history corresponding to the job, wherein the job history includes the job information and the first converted image data as data of the first page of the job.
