Abstract: A storage device stores an operation history in which at least one of four types of data, picture, graphic, symbol, and keyword, in a first data set used in image formation on a sheet by the image forming device is associated with a setting data set manipulated by a user during the image formation. An image reading device reads an original document for use in forming an image and generates a second data set. A comparator compares at least one of the four types of data in each of the stored first data sets with at least corresponding one type of data in the second data set and selects the first data set consistent with the second data set. A screen creator uses the setting data set associated with the selected first data set to create a setting screen for image formation. A display device displays the created setting screen.

Abstract: An image forming apparatus includes an internal environment setting, a setting changing unit, an operation invalidation unit, and a change prohibition unit. The setting changing unit changes an item of the internal environment setting in response to an operation input performed on an operation input unit or in response to an external input. The operation invalidation unit receives an invalidation instruction and invalidates the operation input performed on the operation input unit. The change prohibition unit prohibits the external input from changing an item of the internal environment setting that is locked at the operation input unit in response to the operation invalidation unit receiving the invalidation instruction.

Abstract: A facsimile device includes a communication unit, an analysis unit, and a printing unit. The communication unit is configured to receive, as reception data, both print-scheduled data to be printed and transfer-scheduled data to be transferred to an external device. The analysis unit is configured to analyze a target data portion of the reception data that requires an analysis in order to form an image. The printing unit is configured to print a printable part of the reception data. If at least one of a first error indicating that the communication unit did not receive part of the transfer-scheduled data as the reception data and a second error indicating that the analysis unit has failed in analyzing part of the target data portion corresponding to the transfer-scheduled data has occurred, the printing unit refrains from printing the reception data corresponding to the transfer-scheduled data.

Abstract: An image forming system includes an image forming apparatus connected to a host device via a network. The host device transmits a power-off notification notifying the image forming apparatus on the network that power is to be turned off, together with job information identifying a job, when the host device is powered off. The image forming apparatus searches whether or not there is a job identified by the job information upon receiving the power-off notification from the host device, reads the job identified by the job information out from a job saving unit, transmits the job to the host device and deletes the job that has been transmitted to the host device, from the job saving unit. Further, the host device saves the job transmitted from the image forming apparatus that has received the power-off notification, in a storing unit, and then turns off the power.
