A method is disclosed. For example, the method executed by a processor of a multi-function device (MFD) includes monitoring operating parameters of a component in the MFD, calculating a life set point for the component based on the operating parameters, and changing a default life set point for the component stored in a memory of the MFD to the life set point that is calculated based on the operating parameters.

A processor identifies a specific part composed of a plurality of significant pixels in a mixed-color test image. Furthermore, the processor identifies a color vector. The color vector represents a vector in a color space from one of a color of the specific part in the mixed-color test image and a color of a reference area including a periphery of the specific part to the other. Furthermore, the processor determines which of a plurality of image creating portions of an image forming device corresponding to a plurality of developing colors, is a cause of an image defect, based on the color vector identified from the mixed-color test image.

An information processing device includes: a processor configured to: acquire an invoice to be processed; acquire a document related to the invoice; and perform a process of outputting a suggestion as to a predetermined matter that is to be executed next in accordance with an inconsistency between a content described in the invoice and a content described in the document.

An image forming apparatus has a controller with a first input terminal configured to receive a first signal indicating a state of a first opening/closing portion, a second input terminal configured to receive a second signal indicating a state of a second opening/closing portion, and a third input terminal configured to receive a third signal indicating a state of the first opening/closing portion and the second opening/closing portion. The controller is configured to delay a first notification of an open state of the first opening/closing portion and a second notification of an open state of the second opening/closing portion for a predetermined period after any one of the first signal, second signal, or third signal initially indicates an open state.

An electronic device and a method of presenting an error in power off of the electronic device are provided. The electronic device includes a power switch that is manually set to ON and OFF, an actuator that sets the power switch to OFF, and a controller that outputs a control signal for controlling whether to supply power to the actuator. The electronic device notifies different information based on whether or not the power has been supplied to the actuator after the controller has output the control signal.

Provided is an image forming system including a first image forming device, a second image forming device; and an image reading device. A first hardware processor of the first image forming device causes a first image former of the first image forming device to form a first reference image on a first face of a sheet. A second hardware processor of the second image forming device causes a second image former of the second image forming device to form a second reference image different from the first reference image on the first face of the sheet. A third hardware processor of the image reading device determines whether an image positional deviation is present based on the first reference image and the second reference image that are formed on the first face of the sheet and that are read by the image reading device.

An electronic apparatus includes processing devices including first circuitry, a controller including second circuitry, and a memory storing a time-out time and an extension time. The first circuitry that detects an abnormality, transmits an abnormality occurrence notification, transmits a preparation completion notification, and transmits an extension request. The second circuitry transmits a restart preparation instruction to the processing devices excluding a source of the abnormality occurrence notification, waits for the preparation completion notification until an elapse of the time-out time. The second circuitry restarts the processing devices in response to the preparation completion notification from the processing devices or the elapse of the time-out time. The second circuitry extends the time-out time by the extension time in response to the extension request and restarts the processing devices in response to the preparation completion notification or the elapse of the extension time.

Provided is an image processing apparatus that enhances the distinctiveness of document having a color portion and outputs in monochrome. A monochrome visual determination unit determines whether or not the distinctiveness of the color portion is low when the document data having the color portion is output in monochrome. This color portion includes characters, electronic marks, and graphs, and they are after a specific keyword. A monochrome presentation unit presents to a user a warning or a result of modification when there is the color portion that the distinctiveness is determined to be low by the monochrome visual determination unit. The monochrome presentation unit presents a state in which the document data is output in monochrome by displaying a preview.

In an image forming apparatus, a controller allows a sound output device to output a starting sound and an ending sound at a start and end of diagnostic image formation processing, respectively, determines whether abnormal noise has occurred by identifying data ranging from the starting sound to the ending sound in an diagnostic spectrogram as a comparison target for data ranging from the starting sound to the ending sound in a normal spectrogram to match both the spectrograms in terms of width in a time-axis direction, and identifies a source of the abnormal noise by identifying the data ranging from the starting sound to the ending sound in the diagnostic spectrogram as a comparison target for data in ranging from a timing of start to a timing of end in a timing chart to match the diagnostic spectrogram with the timing chart in terms of width in the time-axis direction.

An image inspector includes a recording device and circuitry. The reading device is configured to read an image on a recording medium. The circuitry is configured to determine whether the recording medium has a wrinkle and an edge folding based on a plurality of positions on the image on the recording medium read by the reading device satisfying a predetermined relation. The circuitry is configured to determine whether the recording medium has the wrinkle based on the predetermined relation, and then determine whether the recording medium has the edge folding based on the predetermined relation.
