Abstract
When a reading error occurs while reading out image data saved in a hard disk, input data which is saved in a RAM is read out and image data is regenerated from the read input data. This enables reprinting by an image formation apparatus alone without requiring a user to re-input image data even when the reading of data occurs due to abnormality of the hard disk.
Claims11
An image formation apparatus, comprising:
- a hard disk configured to save print data;
- a controller configured to generate a plurality of image data including first image data and second image data from the print data read out from the hard disk;
- and
- a printer configured to print the image data on paper, wherein
- the hard disk is configured to save the plurality of image data,
- the controller is configured to
- read out the first image data among the plurality of image data from the hard disk, and
- according to occurrence of a reading error in the hard disk of the image data again read out the print data corresponding to the first image data for which the reading error has occurred from the hard disk before reading out the second image data, and generate image data corresponding to the first image data for which the reading error has occurred, based on the print data again read out.
A method for controlling an image formation apparatus that comprises a hard disk configured to save print data, a controller configured to generate a plurality of image data including first image data and second image data from the print data read out from the hard disk, and a printer configured to print the image data on paper, the method comprising:
- saving the plurality of image data in the hard disk;
- reading out the first image data among the plurality of image data from the hard disk;
- and
- according to occurrence of a reading error in the hard disk of the image data again reading out the print data corresponding to the first image data for which the reading error has occurred from the hard disk before reading out the second image data, and generating image data corresponding to the first image data for which the reading error has occurred, based on the print data again read out.
A non-transitory computer-readable storage medium for storing a program that causes a computer to execute a method for controlling an image formation apparatus that comprises a hard disk configured to save print data, a controller configured to generate a plurality of image data including first image data and second image data from the print data read out from the hard disk, and a printer configured to print the image data on paper, the method comprising:
- saving the plurality of image data in the hard disk;
- reading out the first image data among the plurality of image data from the hard disk;
- and
- according to occurrence of a reading error in the hard disk of the image data again reading out the print data corresponding to the first image data for which the reading error has occurred from the hard disk before reading out the second image data, and generating image data corresponding to the first image data for which the reading error has occurred, based on the print data again read out.
