Image forming apparatus, method of controlling the same, and storage medium

摘要

An image forming apparatus, and a method of controlling it. The apparatus performs, in a case where at least one function out of a plurality of functions of the apparatus ceases to be usable, degeneracy control for operating to provide functions other than the at least one function, and stores information indicating a degeneracy control state is entered. The apparatus controls so as to activate without initialization operation of an image forming mechanism in a case where it is determined that the activation is due to the return from a power saving mode and the information is stored and so as to activate with the initialization operation when the activation is due to a power of the apparatus being turned on.

主权项

1. An image forming apparatus comprising:
a printing unit configured to print an image on a sheet; an engine control unit configured to control the printing unit to execute a preparation operation of the printing unit; an error detection unit configured to detect an error of the printing unit; a function restriction unit configured to restrict a function based on the error detected by the error detection unit; and a power control unit configured to shift, in a state in which the function is restricted by the function restriction unit, the image forming apparatus from a standby state in which power is supplied to the engine control unit to a sleep state in which power is not supplied to the engine control unit; wherein the engine control unit does not control the printing unit to execute the preparation operation of the printing unit when the power control unit returns the image forming apparatus from the sleep state to the standby state in a state in which the function is restricted by the function restriction unit.
