Print Quality Parameter Adaptation for Long Sheet Conveyance Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Printers that support both fixed-size cut sheets and continuous sheets, such as roll sheets, experience higher disorders like printing failures due to sheet conveyance issues compared to standard size cut sheets, particularly when printing long cut sheets or roll sheets.
Innovation Solution
An information processing apparatus and non-transitory computer-readable medium that obtain print settings, including sheet size, with parameters set to prevent sheet conveyance abnormalities. For sheet lengths longer than a certain length, the parameters are limited to higher effectiveness settings to prevent sheet skew and jam, while for standard lengths, all quality options are available, thereby optimizing print settings for reliable printing on long sheets.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If printing is performed using continuous sheets or long cut sheets, then printing versatility is improved, but sheet conveyance reliability deteriorates due to higher occurrence of disorders like sheet skew and jam
Solution Approach 1:
The system dynamically changes print quality parameters based on sheet length. For long sheets exceeding a threshold, the system automatically selects higher effectiveness print quality settings that prevent sheet conveyance abnormalities, while allowing standard settings for normal-length sheets. This parameter adaptation resolves the contradiction by adjusting printing parameters according to the specific sheet conditions.
2Reliability
If print quality settings are optimized for high effectiveness to prevent sheet abnormalities, then sheet conveyance reliability is improved, but printing productivity deteriorates due to restricted quality options
Solution Approach 1:
The system applies high effectiveness print quality settings selectively only when necessary - specifically when sheet length exceeds a predetermined threshold. For standard-length sheets, the system allows all quality options including lower effectiveness settings that enable faster printing. This partial application of the reliability-enhancing measure resolves the contradiction by avoiding unnecessary restrictions on productivity while ensuring reliability when needed.

AI summary
According to aspects of the present disclosure, a CPU of a PC is configured to obtain a print settings used for printing by a printer. The print settings includes an item for a sheet size including a sheet length and an item for a print quality. A parameter settable to the print quality includes a parameter (e.g., a normal or high speed) corresponding to a high conveyance speed of a sheet and a parameter (e.g., a high or the highest image quality) corresponding to a low conveyance speed. When the sheet length of the obtained print size is longer than a particular length, a parameter to be set to the print quality is limited to the high image quality or the highest image quality, and otherwise, the parameter is not limited.
