Image Communication Apparatus Maintenance Mode Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image forming apparatuses fail to distinguish between service person and user inputted print data during a service mode, leading to unnecessary processing complications when performing FAX reception prints, as they do not prohibit facsimile reception and update charging counters incorrectly.
Innovation Solution
An image communication apparatus with a processor and memory that sets an operation mode for maintenance, prohibiting facsimile reception, storing received images in memory, and printing them only when the mode is released, and registering transmission sources to superimpose a pattern on unregistered FAX images.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If facsimile reception is allowed during maintenance mode, then the service person can receive FAX for testing purposes, but printing is performed without superimposing the specific pattern and the charging counter is updated incorrectly
Solution Approach 1:
The patent applies preliminary anti-action by proactively prohibiting facsimile reception during maintenance mode. The control unit is configured to prevent the facsimile reception function from operating when maintenance mode is detected, thereby preventing the harmful effect of incorrect charging counter updates and unauthorized printing before they can occur. This anticipatory prevention resolves the contradiction by eliminating the possibility of FAX reception causing charging errors during maintenance operations.
2Adaptability or versatility
If facsimile reception is allowed during maintenance mode, then FAX can be received for maintenance testing, but processing becomes complicated requiring separate recording of charging counter amounts
Solution Approach 1:
The patent applies the taking out principle by completely extracting the facsimile reception function from operation during maintenance mode. Instead of allowing FAX reception and then managing complex processing rules, the system removes the reception capability entirely when maintenance mode is active. This simplifies the processing by eliminating the need for separate recording logic, pattern superimposition rules, and charging counter management for maintenance-mode FAX prints.
3Quantity of substance
If the charging counter is updated during maintenance mode FAX printing, then revenue is recorded, but the user is incorrectly invoiced for maintenance activities
Solution Approach 1:
The patent prevents the harmful effect of incorrect invoicing by prohibitively blocking facsimile reception during maintenance mode before the charging counter can be incorrectly updated. The control unit detects maintenance mode status and prevents FAX reception operations, thereby eliminating the root cause of incorrect charging counter updates and subsequent invoicing errors. This approach is more effective than attempting to correct invoicing errors after they occur.

AI summary
Facsimile reception is prohibited when an operation mode in which a service person performs printing for the purpose of maintenance is set.
