Facsimile reception is prohibited when an operation mode in which a service person performs printing for the purpose of maintenance is set.

An intermediary device includes circuitry to: transmit, to a server, device information on a device to be monitored acquired from the device via a network; monitor a state of another intermediary device, the another intermediary device being configured to acquire from another device to be monitored device information on the another device and transmit the acquired device information to the information processor; and take over monitoring of the another device, which the another intermediary device kept monitoring, based on setting information for monitoring the another device monitored by the another intermediary device, when the state of the another intermediary device indicates that the another intermediary device has an abnormality.

An image forming apparatus includes a correction unit configured to execute first correction processing to be executed to bring reproduction characteristics of an image formed by an image forming unit close to a target value and second correction processing different from the first correction processing, and an adjustment unit configured to execute a plurality of adjustment processing including the second correction processing, wherein correction processing by the correction unit is set to be executed at a predetermined timing, and wherein in a case that correction processing by the correction unit is executed at the set timing after adjustment processing is executed by the adjustment unit, the image forming apparatus performs control not to execute the second correction processing included in the adjustment processing and to execute the second correction processing after executing the first correction processing by the correction unit.

A maintenance system includes a plurality of apparatuses and a maintenance server. Each apparatus: transmits log data indicating a state of the apparatus to the maintenance server; receives a prediction model from the maintenance server, the prediction model predicting the occurrence of an abnormal state of the plurality of apparatuses; determines whether the abnormal state of the apparatus occurs based on the prediction model to generate a determination result; and transmits the determination result indicating the occurrence of the abnormal state of the apparatus to the maintenance server. The maintenance server: generates the prediction model based on the log data received from each of the plurality of apparatuses; and issues an instruction of a maintenance work for one or more of the plurality of apparatuses that transmit the determination result.

A remote maintenance system is provided that makes it easy to comprehend support received from an operator. In this system, an image forming apparatus receives an image of the image forming apparatus that is photographed by a mobile terminal from the mobile terminal, transmits the image of the image forming apparatus to an operator terminal, receives support information from the operator terminal, and transmits the support information to the mobile terminal. The mobile terminal photographs the image forming apparatus, transmits the photographed image of the image forming apparatus to the image forming apparatus, receives support information from the image forming apparatus, and based on coordinate information included in the support information, superimposes and displays a guide image included in the support information and the photographed image of the image forming apparatus.

An electronic device includes an operation section, first storage, second storage, a processing section, and a display section. The first storage stores data of a file therein. The file includes contents that can be printed. When the operation section receives an instruction for erasing the file, the processing section transfers the file from the first storage to the second storage. The display section displays an inquiry screen for inquiring whether or not to reproduce the file. When the operation section receives an instruction for reproducing the file, the processing section executes print processing or transmission processing. The print processing is processing for printing the contents. The transmission processing is processing for transmitting an email with the file attached thereto. After executing the print processing or the transmission processing, the processing section erases the file from the second storage.

In an image processing apparatus, a processor reads a boot loader from a first storage device, reads a main program from a second storage device by executing the boot loader, and, by executing the main program, transitions to an operation state. The first storage device is mounted on a board on which the processor is mounted. The second storage device is electrically connected with the processor via a bus. When an error occurs during reading of the main program from the second storage device, the processor automatically reads a backup program from the third storage device and displays a screen including warning information on a display device by executing the backup program.

The present disclosure relates to methods and devices for data transmission. The methods is implemented on a data processing unit (220) of a computed tomography (CT) device, the data processing unit (220) is communicatively connected to a plurality of first communication links and at least one second communication link. The method comprises: determining, whether a first communication link group includes at least one failed communication link, the first communication link group including the plurality of first communication links; in response to determining that the first communication link group includes at least one failed communication link, selecting, from the at least one second communication link, at least one target communication link matching the at least one failed communication link; and adjusting the first communication link group to a second communication link group, and the second communication link group including at least the at least one target communication link.

An image forming apparatus includes: an image former that forms an image on a recording medium; and a hardware processor that acquires a read image obtained by reading the recording medium and determines a pass/fail for the image, wherein at the time of proof output, the hardware processor is capable of performing image inspection in which at least a read image obtained by reading a recording medium printed during the proof output is compared with a printing image of a job and a pass/fail is determined, and at the time of actual output of the job, the hardware processor is capable of performing image inspection in which at least a read image obtained by reading a recording medium printed during the actual output is compared with the read image obtained by reading the recording medium printed during the proof output and a pass/fail for an image is determined.

An image reading device includes a reader, an opposing member, and circuitry. The reader is configured to read an image of an object to be conveyed. The opposing member has a plurality of opposing portions that include reference surfaces selectively switchable to be placed at a reading position of the reader. The reference surfaces include two or more identical reference surfaces. The circuitry is configured to determine whether an evaluation reading value of reading values read by the reader on each of the two or more identical reference surfaces is within a prescribed range and perform correction operation of the image reading device with the evaluation reading value within the prescribed range out of the reading values of the two or more identical reference surfaces.
