Image forming apparatus and job execution management method therefor
An image forming apparatus is provided that includes a scanning unit that performs a scanning operation of scanning each page of a document to acquire image data, and a printing unit that performs a printing operation of printing data based on the image data acquired by the scanning unit in parallel with the scanning operation by the scanning unit. The image forming apparatus further includes a control unit that controls the printing unit to stop the printing operation before the printing operation is performed with respect to all the image data acquired by the scanning unit, and controls the printing unit to resume the printing operation with respect to data that is stored in a storage unit based on the image data acquired by the scanning unit while the printing operation is stopped when the data that is stored in the storage unit reaches a first threshold value.
1. An image forming apparatus comprising:
a scanner configured to perform a scanning operation to acquire image data of a document;
a printer configured to perform a printing operation to print data including the acquired image data in parallel with the scanning operation of the scanner;
a processor; and
a memory storing program instructions that cause the processor to
determine a first threshold value that indicates a remaining number of pages that may be printed of a printable page limit value,
determine whether the first threshold value is greater than a second threshold value, and
control the printer to suspend performing the printing operation in parallel with the scanning operation in a case where the first threshold value is equal to or less than the second threshold value, wherein, for the duration of when performance of the printing operation in parallel with the scanning operation is suspended, the processor
controls the scanner to store the acquired image data in a storage device, and
controls the printer to resume the suspended printing operation using the acquired image data stored in the storage device, when a number of pages of the acquired image data stored in the storage device has reached the first threshold value.
2. The image forming apparatus according to claim 1 , wherein the execution of the program instructions further causes the processor to
control the scanner to suspend the scanning operation with respect to the document when a number of pages of the acquired image data has reached the first threshold value.
3. The image forming apparatus according to claim 1 , wherein the first threshold value is set up by a user.
4. An image forming method to be implemented by an image forming apparatus including a scanner configured to perform a scanning operation to acquire image data of a document and a printer configured to perform a printing operation to print data including the acquired image data in parallel with the scanning operation of the scanner, the information processing method comprising:
determining a first threshold value that indicates a remaining number of pages that may be printed of a printable page limit value,
determining whether the first threshold value is greater than a second threshold value, and
controlling the printer to suspend performing the printing operation in parallel with the scanning operation in a case where the first threshold value is equal to or less than the second threshold value, wherein for the duration of when the performance of the printing operation in parallel with the scanning operation is suspended, the processor
controls the scanner to store the acquired image data in a storage device, and
controls the printer to resume the suspended printing operation using the acquired image data stored in the storage device, when a number of pages of the acquired image data stored in the storage device has reached the first threshold value.
5. The information processing method according to claim 4 , wherein the scanner is controlled to suspend the scanning operation with respect to the document when a number of pages of the acquired image data has reached the first threshold value.
6. The information processing method according to claim 4 , wherein the first threshold value is set up by a user.
7. A computer program product comprising a non-transitory computer-readable medium having computer-readable instructions recorded thereon that are executable by an image forming apparatus including a scanner configured to perform a scanning operation to acquire image data of a document and a printer configured to perform a printing operation to print data including the acquired image data in parallel with the scanning operation of the scanner, the computer-readable instructions causing the image forming apparatus to implement processes of:
determining a first threshold value that indicates a remaining number of pages that may be printed of a printable page limit value,
determining whether the first threshold value is greater than a second threshold value, and
controlling the printer to suspend performing the printing operation in parallel with the scanning operation in a case where the first threshold value is equal to or less than the second threshold value, wherein for the duration of when the performance of the printing operation in parallel with the scanning operation is suspended, the processor
controls the scanner to store the acquired image data in a storage device, and
controls the printer to resume the suspended printing operation using the acquired image data stored in the storage device, when a number of pages of the acquired image data stored in the storage device has reached the first threshold value.
8. The computer program product according to claim 7 , wherein the scanner is controlled to suspend the scanning operation with respect to the document when a number of pages of the acquired image data has reached the first threshold value.
9. The computer program product according to claim 7 , wherein the first threshold value is set up by a user.
