PRINTING DEVICE AND PRINTING METHOD - A simplified explanation of the abstract
This abstract first appeared for US patent application 18507133 titled 'PRINTING DEVICE AND PRINTING METHOD
Simplified Explanation
The patent application describes a print head with two nozzle groups, one for ejecting a less visible liquid and the other for ejecting a more visible liquid. A detection section identifies defective nozzles in the first group without printing a test pattern, while a control section prints a test pattern for the second group and information about the defective nozzles using the more visible liquid.
- Print head with two nozzle groups: The print head includes a first nozzle group for ejecting a less visible liquid and a second nozzle group for ejecting a more visible liquid.
- Defective nozzle detection: The detection section can identify defective nozzles in the first group without printing a test pattern on the medium.
- Test pattern printing: The control section prints a test pattern for the second group on the medium using the more visible liquid.
- Information printing: The control section also prints information about the defective nozzles detected by the detection section using the more visible liquid.
Potential Applications
The technology could be used in inkjet printers, 3D printers, and other printing devices where different liquids are used for printing.
Problems Solved
This technology solves the problem of identifying and addressing defective nozzles in a print head without wasting resources on printing test patterns for each nozzle.
Benefits
The benefits of this technology include improved efficiency in nozzle maintenance, reduced material waste, and enhanced print quality.
Potential Commercial Applications
Potential commercial applications of this technology include industrial printing, textile printing, and graphic design.
Possible Prior Art
One possible prior art could be a similar system for detecting defective nozzles in a print head, but without the capability to print information about the defective nozzles using a more visible liquid.
Unanswered Questions
How does this technology impact the overall printing speed of the device?
The patent application does not provide information on how this technology may affect the printing speed of the device. This could be an important factor for users looking to optimize their printing processes.
Are there any limitations to the types of liquids that can be used in this system?
The patent application does not address any limitations on the types of liquids that can be used in the print head. Understanding these limitations could be crucial for users looking to customize their printing materials.
Original Abstract Submitted
A print head has a first nozzle group that includes a plurality of first nozzles capable of ejecting a first liquid onto a medium, and a second nozzle group that includes a plurality of second nozzles ejecting a second liquid that is more visible than the first liquid onto the medium. A detection section is capable of detecting a first defective nozzle, which is ejection failure, from the first nozzle group without printing a test pattern indicating ejection state of each of the first nozzles on the medium. A control section causes a second nozzle test pattern indicating ejection state of each of the second nozzles to be printed on the medium using the second liquid, and information regarding the first defective nozzles detected by the detection section to be printed on the medium using the second liquid.
