Abstract
A controller unit determines the operation mode of a device when an error relating to a color cartridge has been detected. When the controller unit determines that the operation mode of the device is a toner replacement priority mode, the controller unit determines whether or not the number of times a monochrome printing job has been executed is equal to or greater than a threshold value without resolving the error. When the number of times a monochrome printing job has been executed is equal to or greater than a threshold value without resolving the error, the controller unit switches the operation mode of the device to a monochrome performance priority mode.
Claims6
An image forming apparatus that rotationally moves a plurality of recording material storage units that store a recording material to thereby perform printing, the image forming apparatus comprising:
- a moving unit configured to rotationally move the recording material storage unit;
- a switching unit configured to switch the operation mode of the image forming apparatus to either a first operation mode that prioritizes avoiding an error relating to the recording material or a second operation mode that prioritizes a monochrome printing performance;
- and
- a determination unit configured to determine the operation mode of the image forming apparatus when an error relating to a color recording material different from a black recording material has been detected,
- wherein the moving unit moves a recording material storage unit that stores a recording material for which the error has been detected to a different position depending on the determination of the operation mode of the image forming apparatus by the determination unit, and
- wherein, when the determination unit determines that the operation mode of the image forming apparatus is the first operation mode and the number of times a monochrome printing job has been executed is equal to or greater than a threshold value without resolving the error, the switching unit switches the operation mode of the image forming apparatus to the second operation mode.
A method for controlling an image forming apparatus that rotationally moves a plurality of recording material storage units that store a recording material to thereby perform printing, the method comprising:
- moving, in a moving step, rotationally the recording material storage unit;
- switching, in a switching step, the operation mode of the image forming apparatus to either a first operation mode that prioritizes avoiding an error relating to the recording material or a second operation mode that prioritizes a monochrome printing performance;
- and
- determining, in a determination step, the operation mode of the image forming apparatus when an error relating to a color recording material different from a black recording material has been detected,
- wherein, in the moving step, moving a recording material storage unit that stores a recording material for which the error has been detected to a different position depending on the determination of the operation mode of the image forming apparatus by the determination step, and
- wherein, when it is determined that the operation mode of the image forming apparatus is the first operation mode and the number of times a monochrome printing job has been executed is equal to or greater than a threshold value without resolving the error in the determination step, switching, in the switching step, the operation mode of the image forming apparatus to the second operation mode.
A computer readable storage medium on which is stored a computer program for making a computer execute a method for controlling an image forming apparatus that rotationally moves a plurality of recording material storage units that store a recording material to thereby perform printing, the method comprising:
- moving, in a moving step, rotationally the recording material storage unit;
- switching, in a switching step, the operation mode of the image forming apparatus to either a first operation mode that prioritizes avoiding an error relating to the recording material or a second operation mode that prioritizes a monochrome printing performance;
- and
- determining, in a determination step, the operation mode of the image forming apparatus when an error relating to a color recording material different from a black recording material has been detected,
- wherein, in the moving step, moving a recording material storage unit that stores a recording material for which the error has been detected to a different position depending on the determination of the operation mode of the image forming apparatus by the determination step, and
- wherein, when it is determined that the operation mode of the image forming apparatus is the first operation mode and the number of times a monochrome printing job has been executed is equal to or greater than a threshold value without resolving the error in determination step, switching, in the switching step, the operation mode of the image forming apparatus to the second operation mode.
