Abstract: An image forming apparatus includes a main CPU, a sub CPU, a mode control circuit, a voltage monitoring circuit, a reset circuit, and a prevention circuit. The voltage monitoring circuit outputs a first abnormality detection signal if the operating voltage supplied to the main CPU is determined as abnormal. The voltage monitoring circuit outputs a second abnormality detection signal if the operating voltage supplied to the sub CPU is determined as abnormal. The reset circuit resets the main CPU and the sub CPU if at least one of the first abnormality detection signal and the second abnormality detection signal is transmitted. The prevention circuit prevents the transmission of the first abnormality detection signal to the reset circuit in the second mode.

Abstract: An image forming apparatus includes a near field communication portion including a nonvolatile memory and a processing portion, the nonvolatile memory stores information indicating whether or not the output of log information is allowed and when the output of the log information is allowed, the processing portion performs start-up processing while outputting the log information whereas when the output of the log information is not allowed, the processing portion performs the start-up processing without outputting the log information, and a near field communication portion stores the log information output from the processing portion in the nonvolatile memory.

Abstract: An image forming apparatus has a normal mode and a power saving mode. The image forming apparatus includes a printing portion for performing printing, a communication portion for performing a communication process, a system controller for performing operation control of the apparatus and a process concerning communication, and a power supply controller configured to supply power to the printing portion, the system controller, and the communication portion in the normal mode while in the power saving mode, to supply power to the communication portion but to stop power supply to the printing portion. The system controller performs the process concerning communication during the power saving mode, and the power supply controller adjusts a length of a stop time so that average power consumption of the image forming apparatus does not exceed a permissible maximum power, so as to temporarily restore the system controller during the power saving mode.

Abstract: An inkjet printer comprising a printhead for allowing ink to be ejected from a nozzle portion to form an image on a recording medium, a cap member switchable between a sealing position for sealing nozzle surfaces of the nozzle portion and a free position where the cap member is moved away from the nozzle surfaces, and a closing mechanism for closing an opening of the cap member located in the free position.

Abstract: In the order receiving system of the invention, a read/record controller reads image data from a memory card, produces uniquely recognizable ID information and stores the image data in a memory in association with the ID information. An order form issue section issues the user with an order form including the ID information, a thumbnail of the image data associated with the ID information and a blank field for entry of order information on the image data corresponding to the thumbnail. A scanner reads the ID information and order information from the order form filled with the order information by the user. A readout controller stores the order information in the memory in association with the image data corresponding to the ID information.
