Quality Improvement

Epson engages in a variety of quality improvement activities to ensure that all of its products, services, production, and sales are trusted by customers and exceed their expectations.

Supplier Quality Assurance

While Epson manufactures core components such as inkjet printheads in-house, it also relies on suppliers to provide many of the parts necessary for the manufacture of its products. Therefore, Epson is working to improve quality not only within Epson quality assurance program but also with its suppliers, based on their understanding of Epson's approach to quality.
As an example of our activities, we have established Epson's basic approach to quality assurance and the items to be implemented in our Quality Assurance Standards and provide advice on how to improve quality and check the quality status at work sites.

Quality Control Improvement in Manufacturing Processes

The role of the manufacturing process is to create actual products from customer requirements reflected in planning and design. The manufacturing process produces products that are guaranteed to be of appropriate quality based on specifications. In this process, a number of quality control items are specified for the parts and processes that make up the product. Epson dispatches quality control engineers to manufacturing sites in Japan and overseas to ensure that the necessary quality control items are properly managed and quality is guaranteed.

Epson works with local engineers to promote logical problem-solving, human resource development, and quality improvement at Epson manufacturing plants around the world.

Global Sharing of Service & Support Information

Epson has established a service support system in each region of the world to ensure that customers can use its products and services with confidence. As part of its efforts to improve the quality of its service support, Epson holds an Epson Group Service Support Meeting once a year, where service support managers from overseas sales regional head office and some sales companies in each region around the world gather. At the meeting, the status of customer use of products and services and technical information on service support are shared, and discussions and measures for formulating medium- to long-term service support strategies are confirmed. The results of these activities are reflected in service support activities in each region.

Improvement of Employee Quality Control Skills

Training

To enable each and every employee to contribute to quality improvement, we provide quality control training for company-wide employees. After that, employees can systematically receive training in specialized areas necessary for their work and in matters related to E-KAIZEN activities.
In addition, to ensure that employees at overseas sites can receive the same training as employees in Japan, Epson has established a system to train and certify trainers for quality control education at each site, and to provide education and training at each site.
Epson aims to develop human resources capable of identifying and improving the essence of any difficulties or issues that may arise, so that we can realize and deliver products and services that exceed customer expectations.

Kaizen Activities

The entire Epson Group participates in continuous improvement activities. Called "E-Kaizen" at Epson, these activities are used by both teams and individuals to solve problems.
Epson holds an annual Worldwide Team Presentations conference at which the best teams from each of four blocs (Japan, China, Southeast Asia, and Europe/ America) present the results of their kaizen activities. Their accomplishments are judged, and the teams that report the most outstanding accomplishments are recognized with awards. In addition to sharing kaizen presentations within each bloc, Epson reports the best activities in the company newsletter and on the company intranet to motivate others to learn and make their own improvements.

A total of 14 teams presented at the 2025 Worldwide Team Presentations conference. There were four teams from three companies in Japan, four teams from three companies in Southeast Asia, four teams from two companies in China, and two teams from two companies in Europe and North America. After evaluating all the entries, the judges named "Jīn Gāng Zuàn,” a team from Epson Engineering (Shenzhen) Ltd. as the winner of the President’s Award, for their presentation on improving the first‑pass yield rate in first polishing for component flatness.

Awareness raising activities

November is CS & Quality Month across the global Epson Group. During the month, all personnel are encouraged to think about what a commitment to customer satisfaction, as enshrined in the Management Philosophy, means, and to look back on the quality of their own work.
The slogan for activities during the 2025 fiscal year was “Let’s get back to the basics of 5S and the QC story to enhance the quality of our work, solve customer issues, and earn even greater trust.”
We seek to strengthen the relationships we have with our customers and to earn their gratitude by solving their problems. To do so, it is essential that we ensure a level of quality that rewards their trust by practicing 5S and the QC story. Returning to these fundamental practices across the entire company will enhance the quality of our operations.  During the 2025 CS & Quality Month, the Epson Group president re-emphasized the importance of these practices, and recognition was further reinforced through workplace discussions.
Through activities like these, we strive to earn trust, not only by demonstrating a commitment to customer satisfaction but also by showing all stakeholders that Epson genuinely is a good company.
