Automated Offline Post-Processing in Printing Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional print on demand (POD) systems cannot independently utilize post-processing by an inline finisher, requiring users to physically move between the printing and post-processing apparatuses, leading to complex operations and inefficient workflow.
Innovation Solution
A printing system with a job execution unit capable of executing both inline and offline jobs, featuring a detection unit to confirm sheet presence in the paper feed unit and a control unit that automatically initiates post-processing for offline jobs, allowing for remote operation and reduced user intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If post-processing apparatus is located remotely from printing apparatus, then installation flexibility is improved, but user operation complexity increases
Solution Approach 1:
The patent merges the printing apparatus and post-processing apparatus into a unified printing system with integrated control. The control unit coordinates both apparatuses to work together seamlessly, allowing the system to function as a cohesive unit even when physically separated, thus maintaining installation flexibility while reducing operational complexity.
Solution Approach 2:
The control unit acts as an intermediary between the printing apparatus and post-processing apparatus. It receives print jobs, manages the printing process, and automatically transfers printed sheets to the post-processing apparatus, eliminating the need for users to manually intervene between the two remotely located devices.
2Adaptability or versatility
If user must move between printing and post-processing apparatus, then independent post-processing capability is achieved, but time loss increases
Solution Approach 1:
The system ensures continuous automated operation where printed sheets are automatically transferred from the printing apparatus to the post-processing apparatus without interruption. The control unit maintains continuous control over the entire workflow, eliminating idle time and manual intervention gaps between printing and post-processing operations.
Solution Approach 2:
The printing system performs self-service by automatically managing the transfer and processing of sheets without user intervention. Once a print job is initiated, the system autonomously coordinates between the printing and post-processing apparatus, feeding sheets through the conveyance path and executing post-processing tasks independently.
3Adaptability or versatility
If multiple post-processing apparatuses are connected, then processing versatility is improved, but system complexity increases
Solution Approach 1:
The control unit is designed with universal functionality to manage multiple types of post-processing apparatuses. It can identify, communicate with, and control different post-processing devices (such as staplers, binders, folders) through a unified interface, allowing the system to handle diverse processing tasks without requiring separate control mechanisms for each device.

AI summary
A control method for controlling a printing system that includes selectively executing an inline job and an offline job, where the inline job is for executing post-processing on a sheet printed by a printing apparatus by using a post-processing apparatus and the offline job is for executing post-processing on a sheet without executing printing by the printing apparatus by using the post-processing apparatus. The method includes detecting that a sheet has been set in a paper feed unit, setting whether to execute an offline job that uses the sheet if the sheet is detected as being set in the paper feed unit, and controlling the post-processing apparatus to automatically start post-processing corresponding to the offline job in a case where both the system is set to execute the offline job and the system detects that the sheet has been set in the paper feed unit.
