Abstract: An image forming device and an operating method are provided. The operating method included outputting a notification indicating that a cartridge in an image forming device needs to be refilled with toner, in accordance with the notification, performing a preparatory operation for entering a refill mode when it is determined that an operation mode of the image forming device is to be switched to the refill mode for refilling the cartridge with toner, when the preparatory operation is completed, controlling the image forming device such that only an operation related to the toner refilling is performed according to the refill mode, and when the refill mode is terminated, switching the operation mode of the image forming device to a job mode for performing a predetermined job in the image forming device.

Abstract: A server and a method for managing apps based on app usage patterns are provided. The server may include a communication device, a storage, a processor, and a memory storing instructions. The processor executes the instructions to receive, from an image forming device through the communication device, usage data including usage information of apps executed in the image forming device, analyze usage patterns of the apps based on the usage data and store usage pattern data corresponding to the usage patterns in the storage, receive first data corresponding to a first event from the image forming device through the communication device, generate recommendation information related to an app performing an image forming operation corresponding to the first event based on the usage pattern data and the first data, and transmit the recommendation information to the image forming device through the communication device.

Abstract: An image forming apparatus is provided. The image forming apparatus includes a print engine to perform a print job by using a toner filled in a toner cartridge, a communication apparatus to communicate with a memory chip attached to a toner refill apparatus refilling the toner in the toner cartridge, and a processor to, based on an error being found in a toner injection process for the toner cartridge by using the toner refill apparatus, store information related to the error in the toner cartridge.

Abstract: Provided is an image forming apparatus to control capturing of an execution screen displayed. A memory stores at least one application. A user interface device displays an execution screen of an application, to which a user is logged in with an identification (ID) of the user, and receives an input of capturing the execution screen. A processor determines an authority of the ID of the user to capture the execution screen by comparing a security level of the execution screen set based on the data displayed on the execution screen and a security level of the user set with respect to the ID of the user. The processor, in response to the input, controls the capturing of the execution screen, based on the determined authority of the ID of the first user.
