Printer Toner Management IC Chip Read Failure Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing printing apparatuses face challenges in accurately initializing and managing the remaining toner amount due to issues with reading information from IC chips, such as positional deviations and electrical noise, leading to incorrect calculations and delayed notifications for consumable replacements.
Innovation Solution
The printing apparatus employs a management system that includes a toner bottle management unit to handle situations where IC chip information cannot be read correctly, using temporary identification and codes to manage the toner remaining amount accurately and prevent incorrect updates, ensuring proper tracking and timely notifications for consumable replenishment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the printing apparatus reads information from the IC chip to initialize the remaining toner amount, then the management of toner usage becomes automated, but reading failures occur due to positional deviations or electrical noise leading to incorrect initialization
Solution Approach 1:
The system performs preliminary actions by detecting IC chip reading status and preparing alternative initialization methods before actual initialization occurs. When reading fails, the system proactively switches to alternative methods rather than attempting repeated reading operations that would delay initialization.
Solution Approach 2:
The control unit acts as an intermediary between the IC chip reading process and the initialization process. It mediates by detecting reading failures and selecting appropriate initialization methods, preventing direct propagation of reading errors to the initialization result.
2Productivity
If the printing apparatus continues to use an incorrectly initialized remaining toner amount after IC chip reading failure, then the system maintains operation continuity, but incorrect toner usage calculations and wrong notifications are generated
Solution Approach 1:
The system implements feedback by continuously monitoring IC chip reading status and adjusting the initialization method based on reading success or failure. This feedback loop ensures that the initialization process adapts to actual reading conditions, preventing propagation of incorrect values while maintaining operational continuity.
Solution Approach 2:
The system changes the initialization parameter (remaining toner amount) based on reading status. When IC chip reading succeeds, the actual remaining amount is used; when reading fails, alternative methods determine the parameter value, ensuring accuracy is maintained despite reading issues.
3Ease of operation
If the printing apparatus prompts the user to reinstall the toner bottle after IC chip reading failure, then the user is notified of the issue, but the incorrect remaining toner amount may be updated in the IC chip during reinstallation
Solution Approach 1:
The system performs preliminary detection of IC chip reading status before prompting user action. By identifying reading failures in advance, the system can prepare appropriate responses and prevent incorrect data updates during subsequent user operations like reinstallation.
Solution Approach 2:
The system takes preliminary anti-action by preventing incorrect remaining toner amount values from being written back to the IC chip during reinstallation processes. This countermeasure stops the propagation of errors that would otherwise occur during normal reinstallation operations.

AI summary
In a case where reading of identification information of a toner bottle recorded in an IC chip included in an equipped toner bottle and information on a remaining amount of a toner is successful, a printing apparatus (102) notifies a management server (106) of a notification including the identification information of the toner bottle and the information on the remaining amount of the toner, obtains the toner usage amount used in printing processing according to an execution of the printing processing based on a print job, and updates the information on the remaining amount recorded in the IC chip according to a usage amount. In a case where the reading of the information of the IC chip fails, the updating of the information on the remaining amount recorded in the IC chip, according to the usage amount of the toner used in the printing processing according to the execution of the printing processing based on the print job, which is received when the reading fails, is suppressed, and a notification including information indicating that the reading has failed as the information on the remaining amount is transmitted.
