Printer Paper Attribute Matching via Sensor Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional printers do not confirm whether the paper attributes registered by the user after a mismatch error match the actual paper attributes in the paper feeding unit, leading to unnecessary user input and potential incorrect paper exchange.
Innovation Solution
A printer system that compares the attributes of paper correlated to the paper feeding unit with those specified in the printing job and displays the appropriate paper feeding unit for paper placement, allowing for automatic attribute matching and reducing user intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the printer prompts user registration of paper attributes after a mismatch error, then the user can input paper attributes, but the printer cannot confirm whether the registered attributes match the actual paper attributes held in the paper feeding unit
Solution Approach 1:
The printer automatically detects paper attributes using sensors and updates the correlated attributes without requiring manual user input. The system serves itself by using sensors to read paper attributes directly from the paper feeding unit, eliminating the need for users to manually register paper attributes while ensuring accuracy through automated detection.
Solution Approach 2:
The printer uses sensors to detect actual paper attributes and provides feedback by comparing these detected attributes with the attributes correlated to the paper feeding unit. This feedback mechanism allows the system to confirm whether the registered attributes match the actual paper attributes, enabling automatic correction or prompts only when necessary.
2Device complexity
If the printer relies on user-registered paper attributes, then the system can operate with simple user input, but unnecessary user input is required and potential incorrect paper exchange occurs
Solution Approach 1:
The printer automatically detects paper attributes using sensors and updates the correlated attributes without requiring manual user input. The system serves itself by using sensors to read paper attributes directly from the paper feeding unit, eliminating the need for users to manually register paper attributes while ensuring accuracy through automated detection.
Solution Approach 2:
The printer performs preliminary detection of paper attributes using sensors before printing operations. By pre-detecting and correlating the actual paper attributes with the paper feeding unit, the system ensures that the attributes used for printing jobs are accurate and up-to-date, preventing incorrect paper exchange before it occurs.
3Measurement precision
If the printer uses sensors to detect and confirm paper attributes automatically, then paper attribute matching accuracy is improved, but the device complexity increases
Solution Approach 1:
The printer uses existing sensors that are already present in the printing system for multiple purposes, including detecting paper attributes. By making the sensors serve dual or multiple functions, the system achieves accurate paper attribute detection without adding separate dedicated hardware, thus limiting the increase in device complexity.

AI summary
A printer includes a printing unit, a plurality of paper feeding units, a storage unit and a control unit. The printing unit is configured and arranged to execute printing based on a printing job. The paper feeding units are configured and arranged to supply paper to the printing unit. The storage unit is configured and arranged to correlate and store the paper feeding units and attributes of the paper held in the paper supply units. The control unit is configured to compare the attributes of the paper correlated with the paper feeding units with attributes of the paper specified with a printing job, and when there is no paper feeding unit for which the attributes correlated therewith is consistent with the attributes specified with the printing job, to display on a screen one of the paper feeding units in which to place the paper specified with the printing job.
