Image Forming Apparatus Jam Guidance Video Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing image forming apparatuses do not effectively guide operators through the solution process for a recording sheet jam, particularly when the cover is closed without completing the jam solution work, leading to confusion about where to start the troubleshooting process.
Innovation Solution
An image forming apparatus equipped with a display controller that continuously displays a guidance video sequence for solving a recording sheet jam, including sensors to detect the cover and recording sheet status, and a jam solution work progress managing unit to manage the solution work progress, ensuring the operator is directed to the first step when the cover is closed without completing the work.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the guidance video is displayed continuously in a process sequence, then the operator can view the complete troubleshooting procedure, but the operator may close the cover without completing the work and become confused about where to start
Solution Approach 1:
The system detects the cover open/close state via a cover sensor and provides feedback by controlling the display to repeatedly show the first process guidance video when the cover is closed without completing the work, ensuring the operator receives appropriate guidance based on their current state
Solution Approach 2:
The display controller is pre-programmed with the logic to detect when the cover is closed and the work is incomplete, automatically displaying the appropriate guidance video segment without requiring the operator to manually navigate or remember their progress
2Reliability
If the cover sensor detects cover closing and the system repeats the first process video, then operator confusion is prevented, but additional sensors and control logic are required
Solution Approach 1:
The cover sensor serves multiple functions: it detects both the open/close state of the cover and the progress status of the troubleshooting work, eliminating the need for separate sensors while maintaining reliable operation guidance

AI summary
An image forming apparatus includes a display, a display controller, a cover, a cover sensor, a recording sheet sensor, and a jam solution work progress managing unit. The display controller causes the display to continuously display a guidance video in a process sequence when the recording sheet jam occurs. The guidance video shows a work procedure constituted of a plurality of processes for a solution work for a recording sheet jam. The jam solution work progress managing unit manages a progress of the solution work for the recording sheet jam. When the jam solution work progress managing unit determines that the solution work for the recording sheet jam is not performed while the cover sensor detects closing of the cover, the display controller causes the display to repeatedly display a guidance video showing a work procedure for a first process in the solution work for the recording sheet jam.
