Image forming apparatus and method for preventing setting error on sheet size
View Patent ↗Generally, in accordance with one embodiment, an image forming apparatus includes a stacking section, a sensor, a printing unit, a display and a controller. The stacking section is configured to stack a sheet. The sensor is configured to detect the size of the sheet set on the stacking section. The printing unit is configured to form an image on the sheet. The display is configured to display the image. The controller is configured not to display a sheet size except the sheet size detected based on an output signal from the sensor on a setting screen for the sheet size of an image forming object in a detectable status.
1. An image forming apparatus, comprising:
a stacking section configured to stack a sheet;
a sensor configured to detect only a length in a direction which is orthogonal to a paper feed direction for the sheet which is set on the stacking section;
a printing unit configured to form an image on the sheet;
a display configured to display the image; and
a controller configured to display a setting screen for the sheet size and display buttons for multiple detected sheet sizes in a selectable status and display buttons for other detectable sheet sizes together with the buttons for the multiple detected sheet sizes on the setting screen in a non-selectable gray out status when a plurality of the sheet sizes are detected and the controller accepts a call of the setting screen, the controller configured to set the sheet size to be a maximal size when determining the sheet sizes to be multiple and the controller does not accept the call of the setting screen.
2. The image forming apparatus according to claim 1 , wherein
the sensor detects any one of lengths in a longitudinal direction and a lateral direction of the sheet.
3. The image forming apparatus according to claim 1 , wherein
the sensor detects any one of the lengths in the longitudinal direction and the lateral direction of the sheet; and
the controller sets the sheet size of the image forming object to be only one detected sheet size when only one sheet size is detected.
4. The image forming apparatus according to claim 1 , wherein
the stacking section is a manual feeding tray which can be directly accessed from external of the image forming apparatus.
5. The image forming apparatus according to claim 1 , wherein
the stacking section is a paper feed cassette which can be housed inside the image forming apparatus, and can be pulled out from the image forming apparatus.
6. A method for preventing a setting error on a sheet size, which is according to an image forming apparatus comprising a stacking section configured to stack a sheet; a sensor configured to detect the size of the sheet set on the stacking section; a printing unit configured to form an image on the sheet; and a display configured to display the image, including:
detecting only a length in a direction which is orthogonal to a paper feed direction for the sheet on the stacking section based on an output signal from the sensor;
displaying a setting screen for the sheet size;
displaying buttons for multiple detected sheet sizes in a selectable status; and
displaying buttons for other detectable sheet sizes together with the buttons for the multiple detected sheet sizes on the setting screen in a non-selectable gray out status when a plurality of the sheet sizes are detected and a controller accepts a call of the setting screen, the controller is configured to set the sheet size to be a maximal size when determining the sheet sizes to be multiple and the controller does not accept the call of the setting screen.
7. The method for preventing the setting error on the sheet size according to claim 6 , wherein
the sensor detects any one of lengths in a longitudinal direction and a lateral direction of the sheet.
8. The method for preventing the setting error on the sheet size according to claim 6 , wherein
the sensor detects any one of the lengths in the longitudinal direction and the lateral direction of the sheet;
including:
setting the sheet size of an image forming object to be only one detected sheet size when only one sheet size is detected.
9. The method for preventing the setting error on the sheet size according to claim 6 , wherein
the size of the sheet on a manual feeding tray which can be directly accessed from external of the image forming apparatus, and serving as the stacking section, is detected based on the output signal from the sensor.
