LIQUID EJECTION APPARATUS AND PRINT HEAD - A simplified explanation of the abstract
This abstract first appeared for US patent application 18476372 titled 'LIQUID EJECTION APPARATUS AND PRINT HEAD
Simplified Explanation
The liquid ejection apparatus described in the patent application includes a print head that ejects liquid and a drive signal output circuit that corrects the basic drive signal based on temperature information detected by the print head.
- The print head includes a temperature detection portion that detects temperature information.
- The drive signal output circuit includes an amplification circuit that outputs an amplification modulation signal, a smoothing circuit that outputs the drive signal, and a basic drive signal output circuit that corrects the basic drive signal based on the temperature information.
Potential Applications: - Inkjet printers - 3D printers - Industrial printing systems
Problems Solved: - Ensuring accurate and consistent liquid ejection - Preventing issues related to temperature fluctuations
Benefits: - Improved print quality - Enhanced reliability - Consistent performance
Potential Commercial Applications:
- Optimizing Liquid Ejection in Printers for Enhanced Performance
Possible Prior Art: There are existing patents related to temperature-controlled liquid ejection systems in printers and other similar devices.
Unanswered Questions:
- How does the amplification modulation signal affect the liquid ejection process?
The article does not delve into the specific impact of the amplification modulation signal on the liquid ejection process.
- Are there any potential drawbacks to correcting the basic drive signal based on temperature information?
The potential drawbacks or limitations of this correction method are not discussed in the article.
Original Abstract Submitted
A liquid ejection apparatus includes a drive signal output circuit that outputs a drive signal and a print head that ejects a liquid, in which the print head includes a temperature detection portion that detects temperature information, the drive signal output circuit includes an amplification circuit that outputs an amplification modulation signal, a smoothing circuit that outputs the drive signal, and a basic drive signal output circuit that outputs a basic drive signal that is corrected based on the temperature information, and a frequency of the amplification modulation signal when the temperature detection portion detects the temperature information used for the basic drive signal output circuit to correct the basic drive signal is higher than a frequency of the amplification modulation signal when the temperature detection portion detects the temperature information not used for the basic drive signal output circuit to correct the basic drive signal.
