Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing printing devices do not fully optimize operations to achieve faster first printing after a request, as they primarily focus on drying mechanism warmup and neglect other operations that could enhance speed.
Innovation Solution
A printing device with a control system that implements a high-speed printing mode, omitting or reducing maintenance, micro-weave printing, and cutting operations, and adjusting heating and paper feeding processes to expedite the first print without compromising quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If maintenance operations are performed before printing, then printing head reliability is improved, but first printing speed deteriorates
Solution Approach 1:
The patent extracts the maintenance operation from the mandatory pre-printing sequence. The control section determines whether to perform maintenance operations based on printing history and conditions, omitting them when unnecessary (e.g., when a single image is printed or continuous printing is performed). This selective extraction of maintenance operations eliminates unnecessary delays while preserving reliability when needed.
2Manufacturing precision
If micro-weave printing operation is performed, then printing quality is improved, but first printing speed deteriorates
Solution Approach 1:
The patent applies local quality by selectively applying micro-weave printing only to specific regions of the image rather than uniformly to the entire image. The control section identifies end portions of the image in the conveying direction and performs standard printing on those portions while applying micro-weave printing only to central portions where high quality is critical. This localized approach maintains quality where needed while improving overall first printing speed.
3Manufacturing precision
If cutting operation is performed multiple times, then printing medium handling precision is improved, but first printing speed deteriorates
Solution Approach 1:
The patent applies partial action by performing fewer cutting operations than traditionally required. Instead of performing multiple cutting operations to ensure precise printing medium handling, the control section determines that a single cutting operation (or no cutting) is sufficient when printing conditions allow. This reduction in cutting operations eliminates unnecessary time consumption while maintaining adequate handling precision.
4Manufacturing precision
If standby operation is performed for heating temperature stabilization, then printing quality is improved, but first printing speed deteriorates
Solution Approach 1:
The patent applies preliminary action by pre-heating the heating section to a temperature close to the target temperature before printing begins. The control section monitors the heating temperature and determines when stabilization is sufficient, allowing printing to proceed without waiting for complete temperature stabilization. This preliminary heating action reduces the standby time while ensuring adequate heating quality for the print operation.

AI summary
A printing device includes a printing section including an inkjet head configured to eject ink onto a conveyed roll paper, a conveying section configured to convey the conveyed roll paper, and a control section configured to print an image on the conveyed roll paper with the printing section and the conveying section. The control section has a normal printing mode for printing the image with a plurality of operations based on the printing section and the conveying section and a high-speed printing mode for, during first print, printing the image while omitting or changing a part of the plurality of operations included in the normal printing mode according to the operation.
