Display Error Detection and Alert for MFP Web Interfaces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing display screen control systems for image processing devices, such as MFPs, face issues when a heavy load is placed on web servers or networks, leading to incomplete or missing content on the operational panel, causing user confusion and interrupted operations, as users are unable to determine which content is missing and may waste time reacquiring unnecessary information.
Innovation Solution
A display screen control device and method that includes a browser, error detecting part, error determining part, and annunciation controlling part to detect display errors, determine if missing content is necessary for user operations, and control the display of alert images to prompt users to reacquire the screen, thereby minimizing user intervention and operation interruptions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the browser automatically acquires the display screen again when a display error is detected, then the user can continue operations, but unnecessary reacquisitions are made when the missing content does not affect user operations
Solution Approach 1:
The error determining part performs preliminary analysis of the display screen to identify which content is missing before triggering an automatic reacquisition. This preliminary action filters out unnecessary reacquisitions by determining whether the missing content affects user operations, thereby avoiding time waste while ensuring operation continuity when needed.
2Area of stationary object
If the display screen is displayed in the largest size, then the display area is maximized, but the tool bar and other instructional information are not displayed
Solution Approach 1:
The display screen is segmented into different regions: the main content area displayed at large size and the tool bar area containing instructional information. This segmentation allows both the maximized display area and the instructional tool bar to coexist, resolving the contradiction between display size and operational guidance availability.
3Ease of operation
If the user manually determines to reacquire the display screen, then the user has control over the process, but the user cannot know which content is missing and may waste time
Solution Approach 1:
The error detecting part provides feedback to the error determining part about which content is missing in the display screen. This feedback mechanism enables the system to automatically determine whether a reacquisition is necessary, providing the user with controlled information about missing content while maintaining user authority over the reacquisition decision.

AI summary
A display screen control device comprises: a communicating part for performing data communication with a web server; a browser for acquiring a display screen available for the user to make the entry operation from the web server via the communicating part and displaying the acquired display screen on a display part; an error detecting part for detecting whether or not a display error of a content contained in the display screen acquired by the browser is occurred with the display screen being displayed; an error determining part for determining whether or not the content in which the display error is detected is necessary for the user to continue the entry operation when the display error is detected by the error detecting part; and an annunciation controlling part for controlling displaying or not displaying an annunciation image to alert the user to again acquire the display screen on the display part.
