Abstract
An image forming apparatus includes a storage unit that stores image data, an obtaining unit that obtains the stored image data, a printing unit that prints an image generated from the obtained image data on a sheet, a conveyance unit that conveys a sheet contained in a containing unit to the printing unit and conveys the sheet on which the image has been formed external to the image forming apparatus, and a detection unit that detects that the obtaining unit did not obtain the stored image data, where the conveyance unit stops conveyance of the sheet based on the detection by the detection unit during the conveyance of the sheet.
Claims20
An image forming apparatus comprising:
- a storage device configured to store image data;
- a controller configured to obtain the image data from the storage device;
- a printer configured to print, on a sheet and as a printed sheet, an image generated from the image data obtained by the controller from the storage device;
- a conveyor configured to convey, to the printer, a sheet contained in a sheet container and convey the sheet on which the image has been formed by the printer to an outside of the image forming apparatus;
- and
- a display configured to perform notification to a user,
- wherein, based on the controller failing to obtain the image data from the storage device, the controller causes the conveyor to stop conveying the sheet, and
- wherein, based on the stopping of conveying the sheet, the controller causes the display to display a screen that shows that conveying the sheet has been stopped.
A method for an image forming apparatus, the method comprising:
- storing image data in a storage device;
- obtaining, by a controller, the image data from the storage device;
- printing, by a printer on a sheet and as a printed sheet, an image generated from the image data obtained by the controller from the storage device;
- conveying, by a conveyor to the printer, a sheet contained in a sheet container and conveying the sheet on which the image has been formed by the printer to an outside of the image forming apparatus;
- and
- displaying, by a display, to perform notification to a user,
- wherein, based on the controller failing to obtain the image data from the storage device, conveying includes causing the conveyor to stop conveying the sheet, and
- wherein, based on the stopping of conveying the sheet, displaying includes displaying on the display a screen that shows that conveying the sheet has been stopped.
A non-transitory computer-readable storage medium storing a program to cause a computer to perform a method for an image forming apparatus, the method comprising:
- storing image data in a storage device;
- obtaining, by a controller, the image data from the storage device;
- printing, by a printer on a sheet and as a printed sheet, an image generated from the image data obtained by the controller from the storage device;
- conveying, by a conveyor to the printer, a sheet contained in a sheet container and conveying the sheet on which the image has been formed by the printer to an outside of the image forming apparatus;
- and
- displaying, by a display, to perform notification to a user,
- wherein, based on the controller failing to obtain the image data from the storage device, conveying includes causing the conveyor to stop conveying the sheet, and
- wherein, based on the stopping of conveying the sheet, displaying includes displaying on the display a screen that shows that conveying the sheet has been stopped.
