IMAGE FORMING APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18602494 titled 'IMAGE FORMING APPARATUS
Simplified Explanation: The patent application describes a system that detects malfunctioning nozzles in an ejection unit by analyzing test patterns printed on a sheet. It then stores data about the malfunctioning nozzles and performs correction processes to improve printing quality.
Key Features and Innovation:
- Detection of malfunctioning nozzles based on density distribution of scanned test patterns.
- Lower resolution scanning compared to printing for efficient analysis.
- Storage of history data for identified malfunctioning nozzles.
- Addition of correction processes for previously identified malfunctioning nozzles.
Potential Applications: This technology can be used in various industries that rely on precise printing, such as printing presses, manufacturing, and 3D printing.
Problems Solved:
- Efficient detection of malfunctioning nozzles in ejection units.
- Improved printing quality through correction processes.
- Reduction of printing errors and waste.
Benefits:
- Enhanced printing accuracy and quality.
- Cost savings through reduced waste.
- Increased productivity and efficiency in printing processes.
Commercial Applications: The technology can be utilized in commercial printing services, manufacturing plants, and any industry that requires high-quality printing.
Prior Art: Readers can explore prior patents related to inkjet printing systems, ejection units, and printing quality control mechanisms.
Frequently Updated Research: Stay updated on advancements in inkjet printing technology, ejection unit design, and quality control methods for printing systems.
Questions about ejection malfunction nozzle detection: 1. How does the system differentiate between a malfunctioning nozzle and a properly functioning one? 2. What are the potential implications of not detecting and correcting malfunctioning nozzles in printing systems?
Original Abstract Submitted
An ejection malfunction nozzle detecting unit prints a test pattern on a print sheet using the recording head, and detects an ejection malfunction nozzle on the basis of a density distribution of a scanned image of the test pattern. Here, a resolution of the scanned image is lower than a resolution of the test pattern printed on the print sheet using the recording head. Further, a correction processing unit (a) stores into a predetermined storage device history data that indicates the ejection malfunction nozzle for which the correction process was performed, (b) refers to the history data and detects as an additional correction nozzle a nozzle included in the history data, among nozzles corresponding to a predetermined pixel range that includes a pixel corresponding to the detected ejection malfunction nozzle, and (c) performs the correction process for the detected ejection malfunction nozzle and the additional ejection malfunction nozzle.
