Printing Apparatus Dynamic Standby Mode Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Large-sized printing apparatuses require significant initialization time, leading to user wait times and inefficiencies due to varying actuation times influenced by installation environments and processes, necessitating a mechanism to start using the apparatus without prolonged delays while optimizing energy conservation.
Innovation Solution
A printing apparatus with a control unit that determines the most efficient standby mode (first or second standby mode) based on the time difference between the user's start time and the apparatus's shutdown time, automatically actuating the device before the user's start time to ensure stability by the start time, reducing wait times and energy idle periods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the printing apparatus is fully initialized before user start time, then the apparatus stability is improved, but the energy consumption increases due to extended actuation period
Solution Approach 1:
The patent implements dynamic standby mode selection that adapts to different time intervals. The control unit dynamically chooses between first standby mode (full initialization) and second standby mode (partial initialization) based on the calculated time difference between shutdown time and user start time, optimizing the balance between apparatus stability and energy consumption
Solution Approach 2:
The patent changes the initialization parameter (standby mode) based on the time interval. When the time difference is sufficient, the system uses first standby mode with complete initialization. When the time difference is short, the system switches to second standby mode with partial initialization, thereby adjusting the initialization depth according to available time
2Loss of energy
If the printing apparatus enters deep standby mode to save energy, then the energy conservation is improved, but the actuation time increases when user needs to use it
Solution Approach 1:
The system dynamically adjusts the standby depth based on the time interval calculation. The control unit evaluates whether to enter first standby mode (deeper, more energy-saving) or second standby mode (lighter, faster actuation) by comparing the time difference between shutdown and user start time against required initialization time
Solution Approach 2:
The system performs preliminary initialization actions in advance when the time interval allows. By entering first standby mode with sufficient time before user start, the apparatus completes full initialization beforehand, ensuring ready state without delaying user access
3Manufacturing precision
If the apparatus performs complete initialization, then the printing quality is improved, but the initialization time increases
Solution Approach 1:
The patent changes the initialization completeness parameter based on time availability. First standby mode executes complete initialization procedures ensuring high printing quality. Second standby mode executes partial initialization when time is constrained, accepting reduced quality for faster readiness

AI summary
A setting unit that can set the start time when a user starts using a apparatus and a control unit that can make the apparatus enter a non-operation state in either first standby mode or second standby mode where the apparatus can be actuated from the non-operation state in a shorter time than in the first standby mode are provided. The control unit performs control to determine to which of the first standby mode and the second standby mode when the apparatus enters the non-operation state, based on the time difference between a time when an instruction to turn off the apparatus is issued and the start time set with the setting unit.
