Non-Billing Mode Job History Tracking in Image Forming Apparatus
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional image forming apparatuses lack a reliable method to track and prevent improper use of the non-billing mode, leading to potential unauthorized printing and billing issues when service engineers forget to cancel the mode or when users inadvertently or intentionally use it.
Innovation Solution
An image forming apparatus with a setting unit for enabling a non-billing mode and a storage unit to store the history of jobs executed during this mode, including the cumulative number of pages printed, allowing service engineers to detect and record improper usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the non-billing mode is enabled for service engineering operations, then the ease of operation is improved, but the reliability of billing control deteriorates due to potential unauthorized printing
Solution Approach 1:
The system performs preliminary actions by automatically storing job history and page count information before the non-billing mode is exited or abused. The control unit records the cumulative number of pages and job details in advance, so that when improper use occurs, the damage is already documented and can be recovered through billing adjustments.
Solution Approach 2:
The system implements feedback by providing the service engineer with visibility into the stored job history and page count data. This feedback mechanism allows the engineer to monitor non-billing mode usage, understand the impact of operations performed in this mode, and take corrective actions to prevent future unauthorized printing.
2Productivity
If the non-billing mode is used without tracking, then the productivity is improved by allowing free printing, but the loss of information occurs regarding billing accountability
Solution Approach 1:
The control unit performs preliminary recording of job information and page counts before the non-billing mode operations are executed. This ensures that even though printing occurs without immediate billing, all necessary information is captured in advance for subsequent billing calculations and accountability tracking.
Solution Approach 2:
The stored job history and page count data act as an intermediary between the non-billing mode operations and the billing system. This intermediary layer allows free printing to occur while maintaining a record that can be used to calculate billing later, thus preventing information loss while preserving productivity during the printing process.
3Ease of operation
If simple non-billing mode switching is implemented, then the ease of operation is improved, but the device complexity increases to prevent and track misuse
Solution Approach 1:
The control unit automatically performs the tracking and recording functions without requiring additional manual intervention from the service engineer. The system self-manages the storage of job history, calculation of page counts, and maintenance of billing information, eliminating the need for complex manual tracking procedures while maintaining ease of operation.
Solution Approach 2:
The control unit is designed to perform multiple functions: it manages the non-billing mode switching, stores job history, calculates page counts, and prepares billing information. By consolidating these functions into a single multi-functional component, the system avoids the need for separate complex tracking devices or procedures, thus maintaining operational simplicity while preventing misuse.

AI summary
An image forming apparatus includes a setting unit that sets a non-billing mode that is a mode of executing, without performing billing, a job that is set such that billing is performed for execution of the job, and a storage unit that stores a history of a job executed during a period in which the non-billing mode is set, wherein the stored history includes a cumulative number of pages obtained by printing performed by executing a job during a period in which the non billing mode is set.
