IMAGE FORMING APPARATUS AND SHEET CONVEYANCE DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18473451 titled 'IMAGE FORMING APPARATUS AND SHEET CONVEYANCE DEVICE
Simplified Explanation
The abstract describes a patent application for a manual feed tray system in a printer. Here are the key points:
- Manual feed tray located on a side surface of the main housing
- Supply roller conveys sheets from the tray to the print engine
- Pressure plate moves between contact and separated positions
- Push-up cam moves the pressure plate from separated to contact position
- Controller intermittently drives the supply roller while maintaining the pressure plate at the contact position during printing on multiple sheets
Potential Applications
This technology could be applied in various printing devices that require manual feeding of sheets, such as specialized printers for cardstock or envelopes.
Problems Solved
This innovation solves the problem of ensuring proper feeding of sheets from a manual tray to the print engine without causing jams or misalignments.
Benefits
The benefits of this technology include improved print quality, reduced risk of paper jams, and increased efficiency in printing multiple sheets from a manual feed tray.
Potential Commercial Applications
Commercial applications for this technology could include high-volume printing operations, specialty printing services, and office printers that require manual feeding capabilities.
Possible Prior Art
One possible prior art for this technology could be manual feed trays with fixed pressure plates that do not have the ability to move between contact and separated positions.
Unanswered Questions
How does the controller determine the timing for intermittently driving the supply roller during printing?
The abstract does not provide details on how the controller calculates the timing for driving the supply roller intermittently. This aspect of the technology would be crucial for ensuring smooth and efficient printing operations.
What materials are used in the construction of the pressure plate and push-up cam?
The abstract does not mention the materials used in the construction of the pressure plate and push-up cam. Understanding the materials used could provide insights into the durability and longevity of the components in this system.
Original Abstract Submitted
A manual feed tray is located at a side surface of a main housing. A supply roller conveys a sheet on the manual feed tray toward a print engine. A pressure plate is movable between a contact position at which the sheet on the manual feed tray contacts the supply roller and a separated position at which the sheet on the manual feed tray is separated from the supply roller. A push-up cam pushes up the pressure plate from the separated position to the contact position. The push-up cam includes a contact portion configured to contact the pressure plate. A controller is configured to: when performing printing on a plurality of sheets, after moving the pressure plate from the separated position to the contact position, convey the plurality of sheets by intermittently driving the supply roller while maintaining the pressure plate at the contact position.
