  • Patent number: 10992825
    Abstract: According to some embodiments, an image forming apparatus includes at least one storage device, a detection unit, and a control unit. The at least one storage device is logically dividable into a plurality of storage areas each capable of construction of a file system. The detection unit detects an abnormal access to the storage device. The control unit, in response to detection of the abnormal access, performs, for a storage area in which the abnormal access is detected, a recovery action corresponding to the storage area. If the storage area in which the abnormal access is detected does not correspond to a predetermined storage area, the control unit checks and fixes the storage area as the recovery action for the storage area in which the abnormal access is detected.

  • Patent number: 9720780
    Abstract: An information processing apparatus protects data stored in a storage device by saving setting data stored on a first storage device to a second storage device when the first storage device fails, or when an encryption function is enabled or disabled. The process of protecting the date includes, after a reservation for saving setting data is made, saving the setting data, cancelling the reservation, and making a reservation for restoring the setting data. If the setting data is to be restored, it is determined whether the reservation for restoring the setting data has been made, and if the reservation has been made, the setting data is restored to the first storage device.

  • Patent number: 9098046
    Abstract: The present invention aims to shift a printing apparatus to a job processable state by releasing a manual stapling mode in response to an execution instruction of a predetermined job requested by a user. To achieve this, a control method of the printing apparatus comprises: printing an image on a sheet by executing a job; transporting the sheet on which the image was printed, to a post-processing apparatus; causing the post-processing apparatus to perform a post-process; shifting the printing apparatus to a mode of permitting to perform the post-process to the sheet inserted by a user; and controlling, in a case where an execution request of the job is newly accepted, to release the mode according to a kind of the job.

  • Patent number: 9018920
    Abstract: An information processing apparatus capable of suppressing a secondary battery from being charged with an amount of charge current that can apply excessive load on the secondary battery, without a backup power source function of the secondary battery being impaired. When determining that a predetermined type of data is stored in a DRAM to be backed up by the secondary battery, the information processing apparatus selects a first constant current circuit and quickly charges the secondary battery with a large charge current output from the first constant current circuit. When determining that the predetermined type of data is not stored in the DRAM, the information processing apparatus selects a second constant current circuit and normally charges the secondary battery with a small charge current output from the second constant current circuit.

  • Patent number: 8976390
    Abstract: An image processing apparatus having improved user-friendliness in setting the setting values that represent contents of operation to be performed by the image processing apparatus. In a case that a login user has changed at least one setting value during the login, a CPU of the image processing apparatus causes a SRAM to store a setting value before change corresponding to the changed setting value. When the user logs out, the setting value changed by the user during the login is returned to the setting value before change that is stored in the SRAM.

  • Patent number: 8639990
    Abstract: An information processing apparatus capable of overwrite-recording time-series logs indicating an operation history and efficiently holding log information on operations relating to an occurring error. When an error is detected, a filtering object area is set that contains log information for a predetermined time period immediately before the error detection. Then, a type of the occurring error is identified, and log types to be protected are decided based on the identified error type. Among the filtering object area, log recording areas for the decided log types are decided as a to-be-protected log recording area. Subsequently, further log information is recorded so as to avoid the to-be-protected log recording area.

  • Patent number: 8364050
    Abstract: A method for controlling a printing system adapted to perform an adjustment operation with an adjusting unit includes storing information indicating a timing for performing the adjustment operation in a storage unit, causing the adjusting unit to perform the adjustment operation based on the information indicating the timing for performing the adjustment operation stored in the storage unit, causing the adjusting unit to perform the adjustment operation at a timing different from the timing indicated by the information in response to a print interruption occurring in the printing system if a previous adjustment operation has not been performed within a predetermined period of time, and updating the information indicating the timing for performing the adjustment operation stored in the storage unit in response to the adjusting unit performing the adjustment operation to delay a timing for performing a next adjustment operation with the adjusting unit.
