Abstract: An image forming apparatus includes an image forming unit to form an image, a wireless LAN connection unit to connect to a network via wireless, a cause estimating unit to estimate a cause in a case where a connection to the network can not be established by the wireless LAN connection unit, and a display unit to display the estimated cause.

Abstract: An image forming apparatus is disclosed which includes a power-on section which supplies power, a storage section which stores image data, a printing section which prints image data stored in the storage section, an instruction section which accept an instruction to print using the printing section, a processing section which initializes the storage section upon turn-on of the power-on section, a time measurement section which measures time required at least for the processing section to execute processing, a report section which reports that the apparatus is in a state in which the instruction section can accept the instruction to execute printing, a control section which controls, upon turn-on of the power-on section, report of the state in which the instruction section can accept the instruction to execute printing before completion of initialization of the storage section.

Abstract: When there occurs one of a copy JOB, a printer JOB, and a facsimile JOB, the above JOB is classified into four types and registered into one of a copy JOB queue section 73a, a saved JOB queue section 73b, a priority JOB queue section 73c, and an ordinal JOB queue section 73d. When printing of a print section is completed, whether or not a JOB is registered in any queue section is judged and repeatedly monitored in the order of the queue sections 73a, 73b, 73c, and 73d. When a JOB registered is confirmed, the confirmed JOB is promptly executed.

Abstract: An image forming apparatus of the present invention for forming an image based on input image data includes an encryption and decryption unit that encrypts image data using an encryption key prior to the storage of the input image data onto an image storage unit, and decrypts the encrypted image data subsequent to the reading of the encrypted image data from the image storage unit.
