Inkjet Recording Device Liquid Receiving Surface Inclination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Inkjet recording devices face issues with ink mist formation and contamination during borderless recording due to ink ejected beyond the edge of the recording medium not being effectively absorbed, as the ink absorber's proximity to the medium is limited by the transport belt's design.
Innovation Solution
A liquid ejection device with a liquid receiving section positioned outside the transport belt, featuring a downwardly inclined liquid receiving surface that intercepts and collects ink ejected beyond the medium's edge, preventing contact and mist formation by guiding the ink to a collection tray.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the ink absorber is brought close to the recording medium to immediately absorb ejected ink, then ink mist formation is suppressed, but the protruding edge of the recording medium contacts the ink absorber causing contamination
Solution Approach 1:
The liquid receiving section is extracted from the traditional ink absorber position and relocated to the outside of the transport belt in the width direction. This separation allows the liquid receiving section to intercept ink without requiring close proximity to the recording medium, thus preventing edge contact while maintaining effective ink capture through the downwardly inclined receiving surface
Solution Approach 2:
The liquid receiving section acts as an intermediary element positioned between the recording medium and the ink ejector. It intercepts ink that would otherwise contact the recording medium or form mist, channeling it through the inclined surface to the collection tray without allowing direct contact with the recording medium edge
2Productivity
If the liquid receiving section is positioned close to the recording medium, then ink collection efficiency is improved, but the recording medium edge may contact the liquid receiving section
Solution Approach 1:
The liquid receiving section is positioned in the width direction (lateral dimension) rather than only in the height direction (vertical dimension). This spatial reconfiguration allows the receiving surface to intercept ink laterally without requiring vertical proximity that would cause contact with the recording medium edge
Solution Approach 2:
The liquid receiving surface is designed with a downward inclination specifically at the location where ink is ejected. This localized geometric feature enables efficient ink collection by guiding liquid downward into the collection tray, while the overall positioning maintains safe distance from the recording medium edge

AI summary
A liquid ejection device includes a liquid ejection head configured to eject a liquid onto a medium, a transport belt configured to attract and transport a medium at a position facing the liquid ejection head, and a liquid receiving section that is disposed to the outside of the transport belt in a width direction and that forms a liquid receiving surface that receives liquid ejected to a region separated from the medium, wherein the liquid receiving surface inclines downward from a position adjacent to the transport belt, toward outside in the width direction.
