Post-Processing Apparatus Temporary Stop Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the commercial printing industry, existing systems fail to effectively manage the temporary stop of print processing by image forming apparatuses due to lack of communication and coordination with post-processing apparatuses, leading to productivity deterioration.
Innovation Solution
A system where the post-processing apparatus can transmit commands for temporary stops in print processing along with reasons to the image forming apparatus, allowing the latter to acquire and manage temporary stop times, enabling coordinated processing resumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the post-processing apparatus transmits only a temporary stop instruction without reason information, then the image forming apparatus can stop printing, but the image forming apparatus cannot recognize the post-processing apparatus status and timing to resume printing, resulting in productivity deterioration
Solution Approach 1:
The post-processing apparatus transmits feedback information including the reason for temporary stop to the image forming apparatus. This feedback mechanism enables the image forming apparatus to understand the status of the post-processing apparatus and determine the appropriate timing to resume printing, thereby maintaining system productivity while ensuring reliable coordination.
2Productivity
If the image forming apparatus continues printing without receiving stop instructions, then printing productivity is maintained, but the post-processing apparatus cannot handle the print products, causing system bottleneck
Solution Approach 1:
The post-processing apparatus provides feedback to the image forming apparatus about its processing status and capacity. This feedback loop enables the image forming apparatus to adjust its printing speed or pause accordingly, ensuring that printing productivity is maintained only when the post-processing apparatus can handle the output, thus preventing system bottlenecks.
Solution Approach 2:
The printing speed and operation mode of the image forming apparatus are made dynamic based on the real-time status of the post-processing apparatus. The system transitions between different operational states (printing, pausing, resuming) according to the post-processing capacity, allowing flexible adaptation to varying system conditions.
3Adaptability or versatility
If manual carrying or conveyor belt is used to transfer print products, then flexibility is maintained, but labor intensity increases and coordination efficiency decreases
Solution Approach 1:
The system implements automated coordination where the image forming apparatus and post-processing apparatus autonomously communicate and coordinate their operations through transmitted commands and status information. This self-service mechanism reduces the need for manual intervention in transfer coordination, improving operational ease while maintaining transfer flexibility.

AI summary
At least one embodiment of a post-processing apparatus performs post-processing on a product printed by a printing apparatus, and transmits a command for a temporary stop of print processing for a first job and information indicating a reason for the temporary stop to the printing apparatus. At least one embodiment of the printing apparatus receives the command for the temporary stop of the print processing for the first job and the information indicating the reason for the temporary stop, stops the print processing for the first job according to the command for the temporary stop, and acquires a period of time during which the temporary stop continues based on the received information indicating the reason for the temporary stop.
