Abstract: An electronic apparatus includes a first processor and a second processor. The first processor includes a detection unit to detect output of an internal-reset occurrence signal from the second processor, and an identification unit to identify, as a source of the internal reset, the second processor in response to the internal-reset occurrence signal and an input of an identification signal from the second processor. The second processor includes an internal reset unit to internally reset the second processor in response to a malfunction of the second processor, a reset occurrence signal output unit to output the internal-reset occurrence signal in response to occurrence of the internal reset of the second processor, and an identification signal output unit to output, to the first processor, the identification signal indicating the source of the internal reset, in response to the occurrence of the internal reset of the second processor.

Abstract: An electronic apparatus includes a processor for which log information is obtained, a signal monitor configured to monitor monitored signals and detect a change in a changed monitored signal of the monitored signals, and a data acquirer configured to capture groups of signals associated with the monitored signals. The monitored signals include signals for controlling a start of the processor and signals indicating status of power supply to the electronic apparatus. When the change in the changed monitored signal is detected by the signal monitor, the data acquirer stores values of one of the groups of signals associated with the changed monitored signal as a portion of the log information in a storage device.

Abstract: An electronic apparatus comprises: a displacement unit provided to an electronic apparatus main body; a first power source provided to the main body and supplying power to a load provided to the displacement unit; a first connecting unit that opens and closes a first supply path supplying an electric current from the first power source to the load in response to displacement of the displacement unit; a limiting unit provided on the first supply path and limiting an electric current flowing through the first supply path for a predetermined time from when an electric current is supplied from a second power source; and a second connecting unit that opens and closes a second supply path supplying an electric current from the second power source to the limiting unit in response to the displacement, wherein the first connecting unit opens and closes the second supply path in response to the displacement.

Abstract: An image forming apparatus includes a voltage application unit, a target device, a voltage application line, and an electric-current return line. The voltage application unit applies a voltage to the target device through the voltage application line made of a conductor. The electric-current return line made of a conductor connects the target device to the voltage application unit. An electric current that flows upon application of the voltage from the voltage application unit to the target device returns to the voltage application unit through the electric-current return line. The electric-current return line has a length shorter than a path by way of the casing of the image forming apparatus.

Abstract: A developer transport unit which includes an intra-vessel transporting device to transport developer in a developer storage vessel to an ejection unit. The developer storage vessel is detachably attached at one end to an ejection unit. There is a transport/supply device to transport the developer from the ejection unit to a sub-storage vessel, and an intermediate-developer amount detector to obtain an amount of developer present in the sub-storage vessel. Further, there is a control unit to control driving of the intra-vessel transporting device and the transport/supply device.
