Printer Setting Value Recognition Without Display Panel
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Printers without display panels, such as liquid crystal or organic EL panels, face challenges in allowing users to accurately set setting values for printing settings.
Innovation Solution
Incorporating an LED display section, a printing mechanism, an input section, and a memory system that allows for the storage and updating of current, initial, and default setting values, enabling the printer to print images representing these values on the print medium, allowing users to recognize and select the appropriate settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a display panel is used to show setting values, then users can accurately recognize setting values, but the device complexity and cost increase
Solution Approach 1:
The patent uses the printing mechanism to create a visual copy of the setting value information on the print medium. Instead of displaying values on a screen, the system prints representations of setting values (such as graphical icons or symbolic marks) on paper or other media, allowing users to view and recognize the settings externally. This transfers the display function from an electronic screen to a printed output, resolving the contradiction by eliminating the need for a display panel while maintaining setting value visibility.
2Device complexity
If an LED display section is used instead of a display panel, then the device complexity is reduced, but the information display capability is limited
Solution Approach 1:
The patent transitions from a two-dimensional electronic display surface to a three-dimensional printed output that can be physically handled and examined. By printing setting value representations on paper or other media, the system adds the dimension of physical tangibility to the information presentation. Users can view, hold, and reference the printed information as needed, compensating for the limited capability of LED indicators while maintaining system simplicity.
3Adaptability or versatility
If multiple setting values are stored in memory, then setting flexibility is improved, but the device complexity increases
Solution Approach 1:
The patent pre-stores multiple setting values (first setting value, second setting value, and subsequent setting values) in the memory before the user needs to make a selection. This preliminary preparation of multiple options allows the system to quickly present choices without requiring complex real-time processing or generation of setting options. The printing mechanism then displays these pre-prepared options, enabling flexible setting selection while keeping the memory system relatively simple.

AI summary
The processor of a printer prints a setting value settable in a setting item of one in which a setting value is set on a print medium on the basis of input to an input section in a setting mode for setting a setting value in the setting item of one. If the first setting value of the setting item of one is stored in a memory, the processor causes a printing mechanism to print a first image in association with the setting value corresponding to the first setting value of the setting item of one out of the setting values to be printed. If the first setting value is not stored, the processor causes the printing mechanism to print the first image in association with the setting value corresponding to a second setting value of the setting item of one out of the setting values to be printed.
