Image Forming Apparatus Display Update Logic
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In job processing systems, frequent changes to job settings or execution orders by the host computer lead to a high processing burden for display updates on the image forming apparatus, causing delays in job progress confirmation and cancellation processes.
Innovation Solution
Implementing a system where the image forming apparatus only updates its display when a predetermined condition is met after receiving a changed job register, rather than updating immediately, and using a notification system to manage job completion and deletion, thereby reducing processing burden and ensuring real-time job progress monitoring.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the image forming apparatus updates the display device every time the job register changes, then the job progress can be confirmed in real time, but the processing burden on the image forming apparatus increases significantly
Solution Approach 1:
The display device is updated periodically based on predetermined conditions (job completion, job deletion, job execution start) rather than continuously whenever the job register changes. This reduces the frequency of display updates while ensuring critical job status information is displayed timely, resolving the contradiction between real-time monitoring and processing burden.
2Productivity
If the display device is not updated frequently, then the processing burden is reduced, but the job progress cannot be confirmed in real time
Solution Approach 1:
The system implements feedback mechanisms where the display device is updated based on actual job execution status and completion notifications from the image forming apparatus. This ensures that display updates occur at meaningful moments (when jobs complete or status changes) rather than arbitrarily, maintaining reliability while reducing unnecessary updates.
3Adaptability or versatility
If the host computer frequently changes job settings or execution order, then the job processing flexibility is improved, but the display update burden on the image forming apparatus increases
Solution Approach 1:
The patent extracts the display update decision-making function from the image forming apparatus and relocates it to the host computer. The host computer determines when display updates are necessary based on job register changes, and only requests updates when appropriate. This separates the control logic for display updates from the image forming apparatus, reducing its processing burden while maintaining flexibility in job processing.

AI summary
A job processing system includes a host computer and an image forming apparatus connected via a network with each other, the host computer includes a job register acceptor that accepts a job register and a communication device that sends the job register to the image forming apparatus, the image forming apparatus includes a display controller and a job execution controller, the job execution controller controls sequential execution of a plurality of jobs shown in the changed job register in accordance with an execution order of the plurality of jobs, and the display controller keeps from making an update to cause a display of the changed job register immediately after a network interface device receives the changed job register, but makes an update to cause a display of the changed job register when a predetermined display updating condition is achieved after the receipt of the changed job register.
