Solution Overview
Problem
Ink jet recording devices face challenges in efficiently controlling the temperature of recording mediums, particularly those with low thermal conductivity or thick materials, requiring high power heating mechanisms to achieve the appropriate temperature for ink fixation.
Innovation Solution
The implementation of a conveyor system with a reverser and temperature regulators, where the ink is not ejected until the recording medium reaches an appropriate temperature, utilizing a combination of drum heaters and ultraviolet irradiation to maintain the temperature, allowing for flexible and convenient temperature control without increasing the heating mechanism's power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If heating is started immediately before the start of a recording operation, then the temperature control timing is optimized, but a very large heating mechanism with high power consumption is required to rapidly raise the temperature
Solution Approach 1:
The recording medium is heated in advance before the recording operation starts. The heating mechanism operates prior to ink ejection to bring the recording medium to the appropriate temperature, ensuring that when recording begins, the temperature is already suitable for ink fixation without requiring excessive power during the actual recording process
Solution Approach 2:
The heating mechanism's power output is dynamically adjusted based on the recording medium's properties and the current temperature state. The system modulates heating intensity to match the specific thermal requirements of different recording mediums, avoiding unnecessary high power consumption while ensuring adequate temperature control
2Temperature
If a heater is provided to maintain the temperature of recording medium, then the temperature control capability is improved, but the device complexity increases
Solution Approach 1:
The heating mechanism serves multiple functions: it heats the recording medium before recording, maintains temperature during recording, and can compensate for thermal losses after recording. This multi-functional approach reduces the need for separate heating systems and simplifies the overall device architecture while maintaining comprehensive temperature control
Solution Approach 2:
The system incorporates temperature sensing and feedback control to automatically adjust the heating mechanism's operation. Temperature sensors monitor the recording medium's temperature in real-time, and the control system adjusts heating power accordingly, reducing the need for complex manual control mechanisms and improving overall system simplicity

This approach allows for effective temperature control of the recording medium, ensuring proper ink fixation without the need for high power heating, thus reducing energy consumption and enhancing the flexibility of the ink jet recording process.
Implementation Method 1
a first temperature regulator that regulates a temperature of the recording medium in at least a part of a region from the second position to the landing position on the conveyance path
Implementation Method 2
a reverser that returns the recording medium from a first position downstream of a landing position of the ink, which is ejected from the recording operator, to a second position upstream of the landing position along the conveyance path

AI summary
An ink jet recording device includes the following. A conveyor conveys a recording medium. A recording operator ejects an ink to cause the ink to land on the recording medium in a middle of a conveyance path of the recording medium conveyed by the conveyor. A reverser returns the recording medium from a first position downstream of a landing position of the ink, which is ejected from the recording operator, to a second position upstream of the landing position along the conveyance path. A first temperature regulator that regulates a temperature of the recording medium in at least a part of a region from the second position to the landing position on the conveyance path. A hardware processor causes the recording operator not to eject the ink while the recording medium initially passes through the landing position.
