Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional printers require manual or wasteful calibration settings to communicate with sheets containing wireless tags, leading to inefficient operation when switching between different types of sheets with wireless tags.
Innovation Solution
A printer system that includes a scanner to read identification codes on sheets, a controller to determine the sheet type, and a wireless tag reader/writer, which uses acquired parameters to control the printing process, allowing automatic setting adjustments based on the sheet type.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual settings are performed for sheet type communication, then communication with wireless tags can be established, but user convenience deteriorates due to troublesome manual operations
Solution Approach 1:
The system automatically detects sheet type by scanning identification codes on the sheet packaging and self-configures communication parameters for wireless tag reading, eliminating the need for manual user settings while maintaining reliable communication
Solution Approach 2:
The system performs preliminary detection of sheet type information from packaging labels before printing begins, and pre-configures all necessary communication parameters in advance, so that when printing starts, the wireless tag communication is already optimized for the specific sheet type
2Extent of automation
If calibration is performed automatically using the first sheet after refilling, then sheet type settings can be configured, but sheet consumption increases due to waste of calibration sheets
Solution Approach 1:
The system extracts sheet type identification information from the packaging label rather than requiring a blank calibration sheet, thereby eliminating the need to consume sheets for calibration purposes while still achieving automatic configuration
Solution Approach 2:
The packaging label acts as an intermediary carrier that contains the sheet type identification information, allowing the system to detect sheet type without requiring physical calibration sheets, thus preventing sheet waste
3Measurement precision
If various sheet type settings are configured, then communication accuracy improves, but device complexity increases due to multiple settings and calibration procedures
Solution Approach 1:
The scanner and controller serve multiple functions: they detect sheet type information, identify the appropriate wireless tag communication parameters, and automatically configure the system, thereby reducing overall device complexity while maintaining high detection accuracy
Solution Approach 2:
The system replaces manual mechanical settings and physical calibration procedures with automated optical scanning and electronic parameter configuration, simplifying the overall system operation while improving detection precision

AI summary
A printer includes a cassette or tray for storing a sheet to which a wireless tag is attached, a conveyer configured to convey the sheet for printing, a wireless tag reader/writer configured to read and write information from and to the wireless tag when the sheet is conveyed for printing, a scanner, and a controller configured to: control the scanner to read a symbol, determine whether the symbol indicates an identification code that identifies a type of the sheet, upon determining that the symbol indicates the identification code, acquire parameters used for controlling the conveyer or the reader/writer corresponding to the type of the sheet, and control the conveyer and the reader/writer using the parameters when printing is performed on the sheet.
