US 10,120,316 B2 · Information processing apparatus capable of appropriately executing shutdown processing, method of controlling the information processing apparatus, and storage medium

Abstract

An information processing apparatus capable of recovering the apparatus from a state in which software operation is abnormal to a state in which the same is normal. The information processing apparatus is provided with a CPU for receiving an instruction for turning off power of the information processing apparatus. Upon receipt of the instruction, the CPU determines whether or not it is necessary to turn off the power of the information processing apparatus. When it is necessary to turn off the power of the information processing apparatus, the CPU controls the information processing apparatus such that the power thereof is turned off, whereas when it is unnecessary to turn off the power of the information processing apparatus, the CPU controls the information processing apparatus such that the power thereof is not turned off.

A printing apparatus of which power states include at least a normal state, a power saving state, a first turned off state, and a second turned off state, the printing apparatus comprising:

a switch used by a user to turn off the printing apparatus,
a storage device that stores a set of instructions;
and
at least one processor that executes the instructions to:
set one of at least two modes including an initialization mode and a resume mode,
wherein, in the initialization mode, the printing apparatus is started from an initialized state, and, in the resume mode, the printing apparatus is started from a resumed state,
wherein, in a case where the resume mode is set, the at least one processer executes following instructions to:
receive a turn off signal in a case where the switch is operated by the user to turn off the printing apparatus;
control to shift, in a case where no operation is performed in the normal state over a predetermined time period, the printing apparatus to the power saving state,
control to shift, in a case where a predetermined return factor occurs in the power saving state, the printing apparatus to the normal state, without an operation of the switch by the user;
control to shift, in response to the reception of the turn off signal, the printing apparatus to the first turned off state, at least under a condition that the printing apparatus is not in a predetermined state,
control to shift, in response to the reception of the turn off signal, the printing apparatus to the second turned off state, at least under a condition that the printing apparatus is in the predetermined state,
control to shift, in a case where the switch is operated by the user to turn on the printing apparatus in the first turned off state, the printing apparatus to the normal state, and
control to shift, in a case where the switch is operated by the user to turn on the printing apparatus in the second turned off state, the printing apparatus to the normal state,
wherein the predetermined state includes at least one of
a state in which a job to be executed by the printing apparatus is not executed properly,
a state in which an error has occurred on a software in a memory, turning off to the second turned off state being required to recover the image forming apparatus from the error,
a state in which update of a kernel of an Operating System (OS) is required,
a state in which change of the kernel is required, or
a state in which reboot of a module driver is required, and
wherein
power is supplied to the memory during the first turned off state, and
power is not supplied to the memory during the second turned off state,
wherein, in a case where the initialization mode is set, the at least one processor executes instructions to:
receive a turn off signal in a case where the switch is operated by the user to turn off the printing apparatus;
and
control to shift, in response to the reception of the turn off signal, the printing apparatus to the second turned off state so that the printing apparatus is initialized in the next start processing of the printing apparatus, irrespective of whether or not the printing apparatus is in the predetermined state.
