Inkjet Recording Apparatus Ink Level Detection and Notification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional inkjet recording apparatuses without ink sensors cannot detect the color or amount of ink in refillable ink tanks, leading to incomplete ink injection and potential ink exhaustion during printing.
Innovation Solution
Incorporating an ink sensor and controller in the inkjet recording apparatus to monitor ink levels, display inquiry information, and notify users when ink is low, ensuring proper ink injection and preventing printing issues.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If an ink sensor is added to detect ink levels, then measurement precision of ink amount is improved, but device complexity increases
Solution Approach 1:
The ink sensor provides feedback signals to the controller about ink levels in the ink chamber. The controller uses this feedback to determine when ink injection is needed and to monitor ink consumption, enabling automated ink level management without requiring complex manual monitoring systems.
Solution Approach 2:
The system performs self-monitoring of ink levels through the sensor and controller combination. The controller automatically tracks ink consumption based on sensor readings and can prompt users for refilling, reducing the need for external monitoring devices or complex manual tracking mechanisms.
2Reliability
If ink injection completion inquiry processing is implemented, then reliability of ink supply is improved, but loss of time increases
Solution Approach 1:
The system performs preliminary monitoring of ink levels before the ink chamber is completely depleted. The sensor detects ink levels in advance, and the controller prompts users to refill ink before exhaustion occurs, preventing printing interruptions while allowing users to complete tasks between refills.
Solution Approach 2:
The inquiry processing system provides feedback to users about ink status through the display unit. This feedback loop allows users to make informed decisions about when to refill ink, balancing reliability of ink supply with minimal interruption to printing operations.
3Productivity
If notification processing for insufficient ink is added, then productivity is improved by preventing errors, but device complexity increases
Solution Approach 1:
The notification system provides feedback to users when ink levels are insufficient, alerting them through the display unit before printing errors occur. This feedback mechanism prevents productivity losses from printing failures while using a simple notification approach rather than complex error correction systems.
Solution Approach 2:
The system takes preliminary anti-action by notifying users of low ink conditions before actual printing errors can occur. This preventive notification allows users to refill ink proactively, avoiding the harmful effect of printing failures and maintaining continuous productivity.

AI summary
An inkjet recording apparatus includes an ink tank, a recording head, an ink sensor, a monitor, an operation panel, and a controller configured to control operation thereof. The controller receives a completion signal indicating completion of ink injection, and receives a first signal or a second signal from the ink sensor based on whether a predetermined amount of ink is sensed in the ink chamber. Based on the completion signal and receipt of the first signal, inquiry information is displayed on the monitor regarding whether ink injection into the ink chamber is completed. Based on the completion signal and receipt of the second signal, a notification is displayed on the monitor that is based on the ink sensor not sensing the predetermined amount of ink.
