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.
