Embodiment Construction
[0020] With the present invention, even if an error occurs during transition to the energy-saving mode, the error can be prevented from being left unprocessed for a long time. In addition, it is possible to prevent failure to return to the normal mode. Below, based on Figure 1 to Figure 6 Embodiments of the present invention will be described. A digital multi-function peripheral 100 (corresponding to an image forming apparatus) compatible with electrophotographic color printing will be described as an example. The digital multifunction peripheral 100 has a normal mode and an energy saving mode (deep sleep mode) in which power consumption is reduced compared to the normal mode. However, each element described in this embodiment, such as a structure and arrangement|positioning, is an example only, and does not limit the scope of invention.

The present invention provides an image forming apparatus and a control method of the image forming apparatus, which can prevent the error from being left for a long time and failing to return to the normal mode even if an error occurs during transition to the energy-saving mode. The image forming apparatus has a normal mode and an energy saving mode. The image forming apparatus includes a plurality of components, a power supply unit that stops supplying power to a power-supplying portion in an energy-saving mode, a monitoring unit that generates an automatic recovery signal generation unit, and an arithmetic processing unit. When the recovery factor (when there is an interruption signal), the power supply unit is made to supply power again to the part where the power supply was stopped, and the automatic recovery signal generation unit inputs the automatic recovery signal, which is one of the interruption signals, to the monitoring unit after completing the transfer to the energy-saving mode , when an error occurs in the arithmetic processing unit during the transition period, it performs a recovery preparation process, and the recovery preparation process is to input an automatic recovery signal to the monitoring unit after the transition to the energy-saving mode is completed.
Description
technical field [0001] The present invention relates to an image forming apparatus that has a normal mode and an energy-saving mode, and includes a monitoring unit that monitors the state of the apparatus in the energy-saving mode. Background technique [0002] Image forming apparatuses such as digital multi-function peripherals, copiers, printers, and facsimiles have a normal mode and an energy-saving mode. The normal mode is a mode in which a state in which a job can be executed is maintained. The energy-saving mode is a mode in which the power supply to some components is stopped to save power. One example of a technique for solving the disadvantageous situation in which the image forming apparatus shifts to the power saving mode state as described below is known to the public. [0003] Specifically, in addition to the prescribed power-saving mode transition conditions, as the transition conditions for the printing apparatus to transition to the power-saving mode in a s...
