Abstract: A customer service management apparatus that manages a customer service method for a customer staying in a predetermined region, includes: a receiver that receives an image generated by image-capturing with a plurality of customers as subjects; a customer service determiner that determines whether or not customer service is necessary for each of the customers on the basis of the received image; and a hardware processor that determines, when it is determined that customer service is necessary for a plurality of customers, an order of customer service for the plurality of customers for which customer service is necessary.

Abstract: An image forming device including an image former, a primary controller, a secondary controller, one or more sensors, an interface, and a writer. The image former executes image forming processing to form an image on a sheet. The primary controller instructs the secondary controller to control the image former to execute the image forming processing. Each sensor detects a state of the image former and outputs sensor data to the secondary controller. The interface can be connected to a storage medium. The secondary controller generates diagnostic data based on the sensor data. The writer writes the diagnostic data to the storage medium via the interface. The diagnostic data is used by a diagnostic server to perform failure diagnostics and life prediction pertaining to the image forming device, after transfer to the diagnostic server via a transfer device when the storage medium is mounted to the transfer device.

Abstract: The count data recording device includes: a storage unit including N memory areas; and a data restoring unit that detects a corruption in the count data pieces and restores the corruption, wherein the data writing unit records the count data piece using the memory area included in the range of the minor loop according to the predetermined order and shifts the range of the minor loop backward after recording the count data piece using a last memory area within the minor loop.

Abstract: In an MFP, when a count of printed sheets of paper exceeds a predetermined count, a controller reads, from internal counters, a frequency of a stabilization process executed in return, a frequency of a stabilization process executed automatically in printing, a frequency of a stabilization process executed manually based on a user's instruction, and a frequency of return, respectively. When the frequency of the stabilization process executed automatically is small while the frequency of the stabilization process executed manually is large, the controller raises a frequency level of execution of the stabilization process. When the frequency of the stabilization process executed manually is small, the controller lowers the frequency level of execution of the stabilization process.

Abstract: The count data recording device includes: a storage unit that includes N memory areas storing the count data pieces; a data writing unit that writes a count data piece to the storage unit; a data reading unit that reads the count data piece from the storage unit; and a data restoring unit that detects a corruption in the count data pieces stored in the storage unit and restores the corruption, wherein the data writing unit records the count data piece using the memory area included in the range of the minor loop according to the predetermined order and shifts the range of the minor loop backward after recording the count data piece using a last memory area within the minor loop, and wherein the data restoring unit: derives a sorted count data sequence so that values of the count data pieces vary monotonously; derives a count data difference value sequence; and detects and restores the corruption in the count data pieces based on the sorted count data sequence and the count data difference value sequence.
