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.

Abstract

An image forming apparatus has a normal mode and an energy-saving mode. The image forming apparatus includes a plurality of components, a power supply which stops supplying electric power to supply-stop parts in energy-saving mode, a monitor which makes the power supply restart supply of electric power to the supply-stop parts when a recovery factor to normal mode occurs (an interrupt signal occurs), an automatic recovery signal generator which inputs an automatic recovery signal, which is a kind of interrupt signal, to the monitor after completion of transition to energy-saving mode, and an arithmetic processor which, when an error occurs during the transition period, performs recovery preparation processing to have the automatic recovery signal input to the monitor after completion of transition to energy-saving mode.

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...
