Printer Stapling Control via Sheet Type Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional printing apparatuses with a single staplable position face challenges in sheet discharge and paper jam issues due to the need for reversing sheets, which can cause creasing or breaking, especially with certain sheet types, leading to user inconvenience.
Innovation Solution
A printing apparatus and method that includes a controller unit connected to host computers via a network, which controls sheet conveyance and stapling by determining the sheet type and orientation, allowing for selective sheet type changes and stapling position adjustments to prevent paper jams and ensure proper sheet handling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If reverse printing is performed to enable stapling at different positions with a single staplable position finisher, then the number of staplable positions is increased, but sheet curvature and roller influence may crease or break the sheet
Solution Approach 1:
The system performs preliminary identification of sheet type before printing and stapling operations. Based on the identified sheet type, the controller pre-determines the appropriate stapling position and printing method (forward or reverse) to avoid sheet damage while achieving the desired stapling outcome.
Solution Approach 2:
The system creates a mapping between desired stapling positions and actual physical stapling capabilities. By copying the function of multiple physical stapling positions through software control and sheet type-based routing, the system achieves versatility without requiring multiple physical staplers.
2Adaptability or versatility
If sheets are reversed for one-sided reverse printing, then stapling can be performed, but paper jam may occur causing user inconvenience
Solution Approach 1:
The system uses sheet type information to copy the functionality of multiple stapling positions through software control. By mapping user-selected stapling positions to appropriate physical positions based on sheet type, the system maintains ease of operation while preserving stapling versatility.
3Ease of manufacture
If a single staplable position finisher is used, then cost is reduced, but the number of available stapling positions is limited
Solution Approach 1:
The finisher is designed with a universal single stapling position that can serve multiple stapling purposes through intelligent sheet routing and type-based control. The system makes the single physical position perform multiple functions by adjusting sheet conveyance paths and stapling timing based on detected sheet types.
Solution Approach 2:
The system changes operational parameters such as sheet conveyance direction, stapling position selection, and printing method based on detected sheet type parameters. This dynamic parameter adjustment allows a single stapling position to effectively provide multiple stapling capabilities.

AI summary
A control method for controlling a printing apparatus includes printing an image on a sheet, receiving a position subjected to post-processing from a user, controlling, in a case where the received position subjected to post-processing is a first position, to perform post-processing to the received position on the sheet without reversing the sheet on which the image is printed, and, controlling, in a case where the received position subjected to post-processing is a second position, to perform post-processing to the received position on the sheet after reversing the sheet on which the image is printed, and displaying, in a case where the type of the sheet subjected to image printing is of a type unsuitable for reversal, a screen for changing the type of the sheet to be used for printing.
