An image forming apparatus includes an operation device that is connected to the image forming apparatus and receives an operation to the image forming apparatus; a processing unit that performs a predetermined processing by a first application in the image forming apparatus or the operation device; an error detecting unit that detects the error in the processing by the first application; a control unit that starts up a second application to resolve the error upon the error is detected; a transmission unit that transmits error data formed based on the contents of the error from the first application to the second application; and a display unit that displays the operation screen of the second application based on the error data.

An image processing apparatus which reads an image of a document and prints the read image on a sheet includes a detecting unit, an obtaining unit, and a controller. The detecting unit detects a size of the document. The obtaining unit obtains a size of the sheet. The controller performs control such that, in a case where the size of the sheet obtained by the obtaining unit is not a predetermined size, an image in a reading region based on the size of the document detected by the detecting unit is read, and in a case where the size of the sheet obtained by the obtaining unit is the predetermined size, an image in a reading region based on the size of the sheet is read.

A rotation drive control apparatus includes a first mode for counting a detection value of a second detecting member to control a shift amount of a rotation member, based on a detection value of a first detecting member obtained in controlling and rotating a motor, and a second mode for extracting at least one abnormal portion among the motor, control section, mechanism section, and detecting section, based on detection patterns of combinations of a state in which the first detecting member detects a rotation reference position within a predetermined time, or a state in which the first detecting member does not detect the rotation reference position within the predetermined time, and a state in which the second detecting member detects a rotation shift position within a predetermined time, or a state in which the second detecting member does not detect the rotation shift position within the predetermined time.

A data processing apparatus is configured to receive a selection of a first function and search for one or more devices which has the capability to perform that first function. The apparatus may then receive a selection of the one or more devices for performing that first function and, in conjunction, determine whether the selected device has the capability to execute a second function. The device identification data may be stored. Subsequently, if the selected device is determined to be capable of executing the second function, which is different from the first function selected, and the second function is further selected, the previously selected device may be displayed as having the capability to execute the selected second function. Otherwise, the apparatus does not display the previously selected device as being able to execute the selected second function.

A method of producing a machine learning model includes collecting, as training data, data including an image of a document and a size of the document or a size of an actually copied output sheet from a copying apparatus that copies the document on the output sheet, and producing a model for determining whether or not a mark included in the image of the document is identifiable by a user on the document or the copied output sheet based on the training data.

In a multifunction peripheral, image data generated by a scanner section is transferred to an image processor via a data bus. If it is determined that an image processing and another image processing are not executed in parallel, the transfer rate of image data is set to a first transfer rate, whereas if it is determined that the image processing and the other image processing are executed in parallel, one of a plurality of different transfer rates lower than the first transfer rate is selected based on a result of determination of whether or not settings associated with the image processing are predetermined settings and a result of determination of whether or not settings associated with the other image processing are other predetermined settings, and the transfer rate of image data is set to the selected one.

A rotation drive control apparatus includes a first mode for counting a detection value of a second detecting member to control a shift amount of a rotation member, based on a detection value of a first detecting member obtained in controlling and rotating a motor, and a second mode for extracting at least one abnormal portion among the motor, control section, mechanism section, and detecting section, based on detection patterns of combinations of a state in which the first detecting member detects a rotation reference position within a predetermined time, or a state in which the first detecting member does not detect the rotation reference position within the predetermined time, and a state in which the second detecting member detects a rotation shift position within a predetermined time, or a state in which the second detecting member does not detect the rotation shift position within the predetermined time.

An image forming apparatus is provided with USB sockets on front and back sides, and includes a determining unit for determining whether or not a USB device inserted to a front side USB socket is a function enhancement device, and a control unit making, when it is determined by the determining unit that a function enhancement device is inserted to the front side USB socket, the USB device unusable and making, when it is determined that a USB device other than the function enhancement device is inserted, the USB device usable. Thus, it is possible to prevent a USB wireless LAN adapter or the like from being used constantly connected to the front side USB socket and thereby to reduce possibility of USB wireless LAN adapter of being damaged or removed.

A function executing device is configured to send a wireless identifier to a communication device via a first type of wireless communication interface for setting up a wireless connection. The function executing device is configured to determine whether the function executing device is in an error state and, if not, to establish the wireless connection via a second type of wireless communication interface. The function executing device operates in a parent state in the wireless connection. Additionally, print data may be received from the communication device. However, if the function executing device is in an error state the wireless connection is not established via the second type of wireless communication interface.

An image forming apparatus includes a speech input device, a display device, an image forming device, and a control device. The display device displays an image expressed in a preset language for display. The control device functions as a controller that operates in either one of a normal operating mode and an emergency operating mode and recognizes, based on a speech input to the speech input device, a language of the input speech. During operation in the normal operating mode, the controller recognizes a language of the speech input to the speech input device and sets the recognized language as the language for display. During operation in the emergency operating mode, the controller recognizes a language of the speech input to the speech input device and allows the image forming device to form an image representing evacuation information expressed in the recognized language.
