An image forming apparatus includes a sensor configured to detect an object within a predetermined range, a storage unit that stores information about the detected object, and a controller. The controller is configured to control the sensor to detect the object when the image forming apparatus is in a first mode, and in response to the detection of the object, store the information indicating that the object is detected. In response to transition from the first mode to a second mode in which power consumption is higher than the first mode, when the information indicates that the object is detected, the controller performs authentication of a developer cartridge attached to the image forming apparatus, and when the information does not indicate that the object is detected, the controller skips the authentication of the developer cartridge.

An image forming apparatus that performs authentication of a user by a login program that operates on firmware and that, upon detection an abnormality of the login program, restricts execution of a job without causing the login program to terminate, and, while execution of the job is being restricted, controls to enable reception of an operation for disabling the login program via a reception unit for receiving an operation by a user via an operation unit, and, in accordance with the operation for disabling, causes the restricted job to be executed.

An image forming apparatus including: an image processor that executes a job; a setting receiver that receives a setting relating to the job; a job controller that receives an execution request relating to a job predetermined for execution of a job relating to one function and causes the image processor to execute the job relating to the one function; a notifier that notifies a user of an end of each of the plurality of jobs; and a notification controller that determines whether to cause the notifier to notify the end of each of the plurality of jobs on the basis of at least one of a setting relating to each of the plurality of jobs and an attribute of an image to be processed.

A job processing apparatus that is capable of positively stopping a transmission job desired by a user. A transmission job is input according to a user's operation. Uncompleted transmission jobs out of input transmission jobs are managed by a job management table. A first stop instruction for stopping a transmission job is received according to a user's operation. In a case where the first stop instruction is received during display of a configuration screen for making settings of a transmission job, a transmission job input last out of the transmission jobs managed by the job management table is searched for, and the searched-for transmission job is stopped.

The present disclosure pertains to an image reading device that may include an image reader, an operation detector, a correction parameter adjuster, an entry detector, and a document reading controller. The image reader may read an image on a document. The operation detector may detect an operation indicating a start of a reading of the image on the document. The correction parameter adjuster may perform adjustment of a correction parameter. The entry detector may detect entry of a document reading instruction including a reading condition. The document reading controller may check for completion of the adjustment of the correction parameter for the reading condition. If the adjustment of the correction parameter is not completed, the document reading controller may instruct the correction parameter adjuster to perform adjustment of an uncompleted correction parameter and instruct the image reader to read the image.
